Before use
Thank you very much for purchasing the Graupner mz-24 HoTT Pro transmitter.
The manual of this transmitter is made of two parts: The one named Part 1 quick guide is included in the package of the transmitter and this Part 2 in form of programming manual is always updated and is avail­able as download in the web page of the related item on www.graupner.de.
Read both manuals carefully to use the transmitter optimally und first of all to safely control your models. If you experience any trouble during operation, take the instructions to help or ask your dealer or Graupner Service Centre.
To make the research of important information eas­ier, the single paragraphs in this manual are marked with model type symbols. They are the same as the ones used in the transmitter and they show you which paragraph is related to your model type.
Furthermore you can find in many places in the man­ual numbers (page number) or strings in blue charac­ters, for example www.graupner.de. Clicking or tap- ping on brings you directly to the related target.

Starting up the transmitter
Preliminary remarks
Theoretically, the Graupner-HoTT system allows more than 200 models or remote-control systems to be op­erated at the same time. This number will be signifi­cantly less in practice since permits are required for combined remote operation within the 2.4 GHz ISM band. The ultimate limiting factor should be overall the dimension of the available field.
Battery charged?
Since the transmitter is delivered with a partially charged battery, you will need to charge it observing the charge instructions included in the Part 1 of the manual. Otherwise, a warning signal will sound af­ter a short time, and a related message will appear in the basic display after the voltage drops below a certain threshold which can be changed in the line "Batt warning" in the sub-menu "ETC. SET", within the system menu.
Transmitter startup
After the transmitter is switched on by a motor pow­ered fixed wing model the actual control impulse of the output 1 or by helicopter model the throttle ser­vo or rpm controller connected to the output 6 are checked. If this impulse is outside a specifically se­lected band width for idle and then there is the danger that the motor can start, the RF module remains off for safety reasons.
In all other cases by switching on the transmitter the RF module will be switched on too and in the center of the display it will appear the message:
At the same time, audible warning signals sound for a few seconds.
You now have the option of waiting a few seconds until the display disappears automatically or maintain­ing the HF transmissions by manually tapping the ON button, or switching them off by tapping the  OFF button.
You can turn off a receiver that is on and then first touch ON for demonstration purposes. You are then in the basic display of the mz-24 HoTT Pro transmitter:
The blue switch symbol at the top left between the green "TX" and the white "RX" means that the RF transmission of the transmitter is on. (Otherwise the symbol would be gray.)
The green "TX" and white "RX" on the left and right of this switch symbol mean that the currently active model memory has once been linked to a Graupner- HoTT receiver but is presently not linked.
Once this link exists, the field strength display ap­pears to the left of the green "TX" and to the right of the white "RX", and the numeric display underneath shows the current voltage of the receiver power sup­ply, for example:
If the transmitter is turned on while the RF transmis­sion is off, all of this information is not displayed, and the RF switch symbol is gray.
If the following warning appears in the display after the transmitter is turned on, ...
4 Starting up the transmitter
Page 5
... the currently active model memory is not linked to any receiver. Tapping on the SET button you accede immediately the under-menu »Transmitter setting«,
... where you can bind your receiver or, tapping on the
BACK button at the top left of the display to terminate
the procedure.
Tip
The basic procedure for initially programming a new model memory starts on page 42.
Notices
• With this mz-24 HoTT Pro transmitter it is possible to control up to 12 functions. Any servos which are connected to connections 13 and higher remain in their middle position by default and cannot be actuated by the transmitter as standard.
• For the sake of maximum flexibility and to pre­vent unintentional misuse, control channels 5-12 are initially not assigned to any control el­ements, and the servos linked to these chan­nels first remain in their middle position until an operating element has been assigned. For the same reason, nearly all mixers are inactive. Similarly you will find at the begin of the para­graph's description "CTL Set".
• When training, linking or adjusting the remote control, make sure that the transmitter anten­na is always far enough from the receiver an­tennas. If the transmitter antenna is too close to the receiver antennas, the receiver will overdrive, and the red LED on the receiver will shine to indicate that no signal is received. At the same time, the feedback channel will stop working, the field strength bar in the transmit­ter display will disappear, and the current re­ceiver battery voltage will be displayed as 0.0 V. In this moment the transmitter is in the so called Fail safe mode. That is, due to the loss of reception, the servos remain in the last cor­rectly received positions or after a short time in the preset Fail-Safe positions, until a new valid signal is received. In this case, move the two antennas away until the displays return to normal.
CAUTION
Never turn off the transmitter while oper­ating the model! If this nonetheless acci-
dentally happens, do not panic, and wait until the transmitter display goes dark which indi­cates that the transmitter is completely off. This will take at least four seconds. After this time, turn the transmitter on again. Otherwise, the transmit­ter may freeze directly after being turned on, and you will be unable to control the model any more. The transmitter may only be turned on again after it has been turned off and the described procedure has been correctly repeated.

The display is basically operated by touching the de­sired field with a finger or the provided stylus:
By touching the model memory field labeled "M 1" in the above display with a finger or the provided stylus, the "Model memory" selection menu opens.
In this sub-menu, you have the possibility for example to change the model memory by touching the desired model memory and then the SEL button.
Just as described on page , touch NEWto start pro­gramming a Programming a new model , or touch the field MODEL NAME 1 at the upper edge of the display to switch to the "Model name" entry menu, or touch BACK at the top left to return to the pre­vious menu item. In contrast, touch the button SW [Change page] (generally using the rotation method) which is also available in several menus to go to the next page. In the above display of the model memory, this would be to the display of model memories 07 … 12, etc.
Operating the display
Touching one of the three gear icons identified with "B", "F", and "S", special selection menus open on the bottom right from which you can switch to other sub-menus. Starting with the green BASE menu, the selection displaysappear as follows, ...
... it should be noted that the blue function menu de­scribed from page 120, Function menu contains model-type-specific sub-menus and for this reason in divided into a total of three paragraphs.
In the first paragraph starting on page 120 only the sub-menus for "Vehicles", "Copters" and "Boats" model types will be described. Because the same sub-menus are also included in the "blue" menus of the model type "Helicopter" and "Fixed-wing" mod­els, their description is valid for all the model types and for space reasons they will not be repeated in both other paragraphs:
In the second paragraph, beginning on page 154, exclusively the sub-menus related to the model type "Helicopter" will be described excluding the above mentioned "general menus":
And in the third paragraph, beginning on page 182 also excluding the previously described "general menus", exclusively the sub-menus related to the "fixed-wing" model type, in which the menus of a "motor powered model" …
... distinguishes from the menus of a "Glider" model:
The purple System menu which can be accessed tapping on "S" and whose description begins on page
220, is displayed as follows …

Warnings
In the display of the mz-24 HoTT Pro transmitter ap­pear different warning windows. These can be divided into two groups:
"Warning" display
These warning windows primarily appear after the transmitter is turned on and indicate certain operating states. In the following illustration, for instance, the red dot after "CH1-POS" indicates that the throttle servo connected to the output 1 in fixed-wing models, or the throttle servo and to output 6 on an helicopter model, is not in the idle position and there is the risk of a runaway engine. Until this state persists, the con­tent of the underneath field are obscured for safety reasons ...
... until the Throttle/Pitch control stick is not in the idle area:
Basically the it is the same for the warning option "Thr. HOLD", with the difference that the sub-men "WARN-
ING" of the system menu it can be selected, depend-
ing on the model, if the motor stop function on/off must be worn:
Notice
In no case you should use the possibility of the servo reverse of the channel 6 for helicopters and
channel 1 for other model types to reverse the direction in which the related control stick works. Be­cause the switch-on warning "CH1-Pos" as the "Thr.
HOLD" function do not follow this kind of reverse control
direction. To reverse the control direction use exclusively the possibility offered by the "Pitch curve" menu for helicopters models and "Throttle curve" for all the oth­er model types.
Touch SET with a finger or the provided stylus to go directly to the »TX ctl« display (Transmitter setting) in which you can link the receiver to the model memory as described in the related paragraph ...
Or touch the BACK button at the top left to terminate the procedure.
If instead by switching the transmitter, there is already a receiver bound to the model memory and inactive Thr.POS warning, the transmitter will switch on and the RF module will also be active. Otherwise in the middle of the display it will standardly appear the fol­lowing page and at the same time an acoustic warn­ing will be emitted.
You now have the option of waiting a few seconds until the display disappears automatically or maintain­ing the HF transmissions by manually tapping the ON button, or switching them off by tapping the  OFF button.
In the field between the two green lines, the message "RC signal" indicates that the transmitter is set to nor­mal remote control. Alternately, messages such as "TEACH signal" or "PUPIL signal" can appear here. Another – possible – variant is to display "SET F/S" as an indication that no fail-safe settings have yet been made.
Notices
• By default,only the monitoring of the "Warn -
ing" sub-menu is activated in the display of
the sub-menu "Warning"of the system menu.
• By selecting REV in the "Thr.HOLD" line of the "Warning" sub-menu the transmitter can remind you to switch this function safely on.
8 Warnings
Page 9
"Acute warning" display
You can open this display by touching mz in the mid­dle of the transmitter's basic display ...
Touch
... and touch the BACK button at the top left to close the display.
If acoustic warnings sound and the normal transmit­ter display is covered by this display, take note of the message in red. An example would be because the transmitter's supply voltage has reached the warning threshold set in the sub-menu "»ETC. SET" of the SYSTEM menu:
At the same time, the display contrast is reduced to 05 to save power.
This warning can be kept from reappearing by touch­ing the ON button at the top right then deleted by touching the BACK button at the top left in the dis­play. (In specific cases, stop operating the model as soon as possible and charge the transmitter).
The red number at the top right of each warning field shows the number of current warnings; in the above example, the warning is the fourth one. This count can be deleted by touching the CLR button at the top left. All other warnings in this display can be handled in the same way. However, in the case of a field strength alarm, you can also suppress other alarms triggered by the low field strength by touching the ON button under "STRENGTH ALARM" and switch it to OFF.
CAUTION
A switched OFF "Strength alarm" will not automatically be set to the "ON" position when the transmitter will be switched on
the next time.

3. In the sub-menu »TX ctl«, depending on the num­ber of channels used for the connected flight sim­ulator or for the Training mode, you can select in the line "DSC output" one of the following modes: PPM10, PPM16, PPM18 und PPM24. Default set­ting: PPM10.
Notice
Given the numerous flight simulators on the mar­ket, it is possible that the contacts on the jack plug or DSC module may have to be adapted by
Graupner Service.
Attention
When your transmitter is directly connected to a desktop computer or laptop by a connecting ca-
ble (DSC cable) and/or a computer interface is connected to your simulator, the transmitter may be de­stroyed byelectrostatic discharge. This type of connec­tion should therefore only be used if you protect yourself from electrostatic discharge while operating the simula­tor by wearing a commercially available grounding arm­band. Graupner therefore strongly recommends only using wireless simulators.
DSCsocket
The abbreviation "DSC" is from the initial letters of the original function, "direct servo control". With the HoTT system, "direct servo control" using a diagnostic ca­ble is not possible for technical reasons.
The standard two-pin DSC socket on the back of the mz-24 HoTT Pro transmitters functions as a TRAINER or PUPIL socket as well as an interface for flight sim­ulators or other external devices.
To ensure a correct DSC connection, observe the following:
1. Perform any necessary adaptations in the menu. To adapt to the transmitter to a trainer system,see
the description of the "Trainer" menu.
2. Connect the other end of the connecting cable to the desireddevice while observing the relevant op­erating instructions.
Tip
Make sure that all the plugs are securely inserted in the respective sockets, and only use the provided plug-in connections with a 2-pin jack plug on the DSC side.
The so-called DATA socket is found under the back cover of the mz-24 HoTT Pro transmitters:
This is for connecting the optional Smart Box ( order No. 33700) or alternatively for an external Bluetooth module (No. S8351).
Further information on the Smart Box and the Blue­tooth module can be found in the main Graupner FS catalogue and on the Internet at www.graupner.de for the respective product.
Data socket

The headphone connection is found left of center un­der the back cover of the mz-24 HoTT Pro transmit­ter:
The socket is for connecting commercially available ear buds or headphones with a 3.5 mmstereo jack. (Not included in the set.)
When headphones are plugged in, the transmitter's speaker is turned off and the stylized icon of a head­phone is depicted in color and not gray in the basic display.
In addition to acoustic signals from the transmitter, signals and messages associated with the "Teleme- try" menu are output via this connection. These mes­sages are in German by default. Further information can be found under "Announces" in the ""Teleme-
try"" section.
Ear phones port
Card slot
Micro-SD and micro-SDHC
Thecard slot for micro-SD und micro-SDHC memory cards is found on the right of center under the back cover of the mz-24 HoTT Pro transmitters:
In addition to the micro-SD memory cards that come standard with the mz-24 HoTT Pro, all convention­al micro-SD memory cards with up to 2 GB and mi­cro-SDHC cards with up to 32 GB memory can be used. The manufacturer recommends using memory cards with a maximum of 4 GB since this capacity is normally sufficient.
The memory card that is provided for the transmit­ter is inserted into the slot behind the cover with the contacts facing up and then locked in place. After the memory card is inserted, the transmitter cover can be closed.
After the provided memory card included in the mz- 24 HoTT Pro set or another memory card has been inserted in the transmitter at least once, the card is ready for use directly after the transmitter is turned on. If the transmitter is turned on after the memory card is inserted, the stylized memory card icon is displayed in color and not gray in the basic display. Otherwise, a few folders are first created on the memory card.
Removing the memory card
Open the cover on the back. Press the SD card slight­ly toward the card slot to unlock it and then remove it.
Capturing / saving data
The data memory on the SD card is linked to timer 1: Once this starts, data storage also starts assum­ing that an appropriate memory card is in the card slot and there is a telemetry link with the receiver. Data storage stops when the timer 1 is stopped. Timer 1 starts and stops as described in the section "Timer". The data writing on the memory card is remarked by an animation of the memory card symbol.
After data storage is finished, an (empty) "Models" folder and "LogData" folder appear on the memo­ry card. Finally, the log files are saved in subfolders called "Modelname" named according to the structure 0001_year-month-day.bin, 0002_year-month-day.bin. If in contrast a model memory is still nameless, the corresponding log files are saved in a subfolder en­titled "NoName" after the memory card is removed from the transmitter and inserted in the card slot of a desktop or laptop computer. The data can be eval­uated on a compatible computer using the programs found on the downloads page for the transmitter un­der www.graupner. de.
Notice
Please note that for technical reasons NO data representation is possible during the reproduc­tion of MP3 data.

Mini-USB connection
Located under the rear cover of the mz-24 HoTT Pro transmitter, there isa connection socket for software updatesas well as the date andtime settingfrom a desktop or laptop with one of the Windows operating systems (XP, Vista, 7 ... 10):
The USB cable that comes with the set is plugged into this socket. The procedure for obtaining software up­dates through a computer is described in the software package instructions.
The software that the computer needs as well as the appropriate USB driver can be found on the download page at www.graupner.de for the respective product.
After the required driver and software are installed, the transmitter can be updated as needed using this con­nection, or the date and time can be set.
Tip
In order to be aware of important software updates, you should therefore register at https://www.graupner.de/
de/service/produktregistrierung.aspx. This will allow you
to automatically receive updates by e-mail.
Importing and exporting model memories
To exchange data between transmitters of the same make or to backup data, model memories can be cop­ied to the inserted memory card, or from the memory card to the transmitter. More information can be found in the section "Import from SD card" or "Export to SD
card"..
Notices
• Some of the special characters used in mod­el names cannot be transferred to FAT and FAT32file systemsdue to the specific restric­tions of these file systems used by the mem­ory cardand are therefore replaced by a tilde (~) during the copying process.
• The model memories of the mz-24 and mz- 24 Pro transmittersare in principle compati­ble, BUT:
In order to import from an SD card in another a transmitter type, the desired model memory must be copied or moved to a corresponding directory on a desktop or laptop. For example from \\Models\mz-24 to \\Models\mz-24pro or vice versa.
More information on "import from SD card" After importing from an SD card,you always
need to check each and every model func­tion and in particular adapt the control and switch functionsto the respective transmitter.

Starting up the receiver
Preliminary remarks
Notice
With this mz-24 HoTT Pro transmitter it is possi­ble to control up to 12 functions. Any servos
which are connected to the receiver outputs 13 and higher remain in their middle position by default and cannot be actuated by the transmitter.
As described in the manual of the related receiver, after switching it on a LED indicates the missing re­ception, so long as "its" transmitter is out of range or switched off or simply the wrong model memory has been selected in the transmitter. This means that a link has not (yet) been established with a Graupner-HoTT transmitter.
To establish a connection with the transmitter, first the Graupner HoTT receiver must be "bound" to its model memory in its Graupner HoTT transmitter. This pro­cess is known as "Binding". This "binding" is however required only once for each receiver-model memory combination or, after changes have been made to one or more model memories (see page 39), only once for each transmitter-receiver combination . Therefore you need to perform a "binding" only after buying a new transmitter or other receivers or for example if you have changed model memory (and you can re­peat it at any time).
Notice
If the LED of your receiver indicates that it is ready
for use and the receiver does not react to the SET
button and to the control movements, then you would be better to check the polarity of your receiver power supply.
On-board voltage display
When a telemetry link exists, the current voltage of the receiver power supply appears in the transmitter display in white.
Temperature warning
If the receiver temperature falls below a threshold which can be set in the receiver (-10°C by default) or exceeds a top warning threshold (+55°C by default) which can also be set in the receiver, the receiver emits a warning in the form of a beep that repeats approximately once per second.
Note the installation instructions for the receiver, re­ceiver antennas and servos on page 16.
Notice
If you are using a speed controller with an inte­grated BEC* in addition to the receiver battery,
the plus pole (red cable) may have to be removed from the 3-pin plug depending on the speed controller. In this regard, take note of the related information in the speed controller instructions.
Use a short screwdriver to careful­ly lift the middle tab of the plug (1), remove the red cable (2), and use electrician's tape to protect against shorts (3).
Reset
To reset the receiver, hold down the SET button on the top of the receiver while turning on the power.
If the reset is performed while the transmitter is switched off or with a not bound receiver, the LED on the receiver indicates the actual status according to the description included in the package. If there is no different description, release the button after about 3 seconds.
If the reset is performed with a not bound receiver, you can then start a binding process at any time.
If a linked receiver is reset and the associated model memory is active in the turned-on transmitter, the LED indicates for about 2-3 seconds, accordingly to the description included in the package of the receiver, to indicate that your transmitter/receiver system is ready to use.
Note
Through a RESET ALL of the settingsin the re­ceiver are brought to the factory settings with the exception of the HoTT synchronization informa-
tion! If a reset is performed accidentally, all of these settings
that were made using the "Telemetry" menu in the re- ceiver should be restored.
Resetting is particularly recommendable when you want to switch a receiver to a different model. This makes it easy to keep settings which do not match from being transferred.

Channel mapping
The function of each channel is determined by the transmitter and not the receiver. The channel map­ping can be changed directly in the receiver program­ming the "Telemetry" menu and indirectly through the menu point "Transmitter output" of the base menu.
Installing the receiver
 WhateverGraupner receiver system you use, the procedure is the same.
For aircraft models, the receiver is installed behind a strongbulkhead or it is protected against dust and splash waterincar and ship models. When you install the receiver, make sure that it is not excessively air­tight to prevent it from overheating during operation.
The receiver may not directly touch the fuselage or chassis since they can directly transmit motor vibra­tion or impact from landing. When installing the re­ceiver in a model with a gas motor, all of the parts must be protected to prevent exhaust or oil from pen­etrating. This holds true in particular for the ON/OFF switch that is installed in the shell of the model in most cases.
Install the receiver so that the connecting cables for the servos and power supply remain loose, and so that the receiving antennas are at least 5 cm from all large metal parts or wires that do not directly originate from the receiver. This includes carbon fiber parts, servos, electric motors, fuel pumps, all types of ca­bles, etc. in addition to steel parts.
It is preferable to install the receiver away from all oth­er installed parts at an easily accessible location in the model. Servo cables may not be wound around antennas or run next to them.
Note that the cables can shift under the influence of acceleration during flight. You therefore need to make sure that the cables cannot move to be directly ad­jacent to antennas. Moving cables can interfere with reception.
Installing the receiver
Installing the receiver antennas
In case of single antenna, the orientation is not crucial. In the case of diversity antennas (two antennas), the
active end of the second antenna should be at a 90° angle from the end of the first antenna, and the dis­tance between the active ends should ideally be more than 125 mm.
If the fuselages are made of carbon fiber, the ends of the antennas should extend from the fuselage by at least 35 mm. If necessary, exchange the approx. 145 mm standard antennas for HoTT receivers with the 300 mm or 450 mm long antennas No. 33500.2 or 33500.3.
Servo connections and polarity
The servo connections of the Graupner-HoTT receiv­er are numbered. The supply voltage runs through all the numbered connections. The polarity of the plug-in system cannot be reversed. When inserting the plug, note the small bevels on the side. Do not apply force.
Attention
Do not reverse the polarity of these connections! This can destroy the receiver and connected de­vices.
Notice
In compact receivers like the GR-12L HoTT the outputs 1 … 6 are reverse of 180° if compared to
bigger receivers, for this reason we recommend to pay a very lot of attention while you connect any plug to the receiver. If applicable, use a V or Y cable (No.
3936.11).

Installing the switch
All of the switches must be installed so that they are not influenced by exhaust or vibration. The switch knob must be freely accessible over its entire oper­ating range.
Installing the servos
Always install the servos with the provided rubber vi­bration damper, see the following installing notices. This is the only way to protect them somewhat from excessive vibration.
• Install the servos on rubber grommets with tubular
brass spacers to protect them from vibration. Do not overtighten the fixing screws; this could coun­teract the vibration protection provided by the rub­ber grommets. The system offers both safety and vibration protection for your servos when the servo fixing screws are properly tightened. The follow­ing figure shows how to correctly mount a servo. The brass spacers are inserted from below into the rubber grommets:
... they should never be connected as follows:
• In contrast, the sequence for connecting the ser­vosdepends on the model type. Refer to the con­nection assignments for Helicopter models and
Fixed-wing models.
WARNINGS
• Technical defects of an electrical or mechanical naturemay cause motors to start without warning,or may gen­erate flying partswhich can cause sig­nificant injuryto you and others!
• Avoid every kind of short-circuit! Short-circuits can destroy parts of the remote control system and cause se­rious burns or explosions depending on the circumstances and the battery charge.
• All parts driven by the motor such as air and water propellers as well as he­licopter rotors, exposed gears, etc. always pose an injury hazard. Never touch these parts! A fast-rotating pro­peller can cut off a finger! Make sure that no other objects come into con­tact with driven parts.
• The servo arms must be freely movable throughout their operating range. Make sure that no linkage parts block the free movement of the servo.
• Connect the receiver's power supply cable(s) or the servo connecting cable to the receiver as fol­lows ...

Page 17
• Once the battery is connected or the motor is running, always maintain a safe distance from the hazard area posed by the propulsion system!
• During the programming process, make sure that a connected gas en­gine or electric motor cannot acciden­tally start. Disconnect the fuel supply or drive battery beforehand.
Notices
• Protect all equipment from dust, dirt, moisture and other foreign parts. All equipment must be protected from vibration as well as excessive heat or cold. The models may only be oper­ated remotely in normal outside temperatures such as from -10°C to +55°C.
• Avoid shock and pressure. Check for dam­age to the housing and cables. Devices that become wet or damaged may not be used anymore even if they dry out.
• Only use the components and spare parts that we recommend. Always use matching, original Graupner plug-in connections of the same design and material.
• When running the cables, make sure that they are not excessively tight, kinked, or severed. A sharp edge can also damage insulation.
• Make sure that all of the plug-in connections are tight. When disconnecting the plug-in connections, do not pull the cables.
• No changes may be made to the devices. This will void permission to use the device along with the warranty. If appropriate, send the relevant device to the responsible Graupner Service Center
Range and function test
Before every use, check the range and functioning. Firmly secure the model, and make sure that no one is nearby.
Perform at least one complete function test on the ground, and run through an entire flight simulation to determine if there are any problems with the system or the programming of the model. Always follow the instructions under Range test.
WARNING
If the range and function test as well as the flight simulation are not performed
completely and conscientiously, malfunc­tions may go unrecognized and reception may be lost which could cause a loss of control or even cause the model to crash. This canresult in major property damage and/or personal injury.

Servo noise filters for extension cables
No. 1040 The servo noise filter is required when using lon-
ger-than-usual servo cables. The filter is connected directly to the receiver output. In critical cases, a sec­ond filter can be placed on the servo.
Electrical ignitions
Ignition systems of gas engines also generate inter­ference that can impair the functioning of remote con­trols.
The power for electrical ignitions should always be from a separate source.
Only use interference-suppressed spark plugs and spark plug connectors and shielded ignition cables.
The receiver should be at a sufficient distance from the ignition system.
Model function
WARNING
• Neverfly the model over observersor other pilots. Never endanger people or animals. Never fly close to power lines. In addition, never operate your model close to locks and open nauti­cal traffic. Do not operate your model on open roads, highways, paths, pub­lic walkways, etc.
• Never turn off the transmitter while operating the model! If this nonethe­less accidentally happens, do not pan­ic, and wait until the transmitter dis­play goes dark which indicates that the transmitter is completely off. This will take at least three seconds. Af­ter this time, turn the transmitter on again.
Page 18
• Otherwise, the transmitter may freeze directly after being turned on, and you will be unable to control the model. The transmitter may only be turned on again after it has been turned off and the described procedure has been correctly repeated.
• When operating towed models, main­tain a minimum distance of approxi­mately 50 cm between the participat­ing receivers or their antennas. Using the satellite receiver is an option. Oth­erwise, malfunctions from the feed­back channel are possible.
Checking the transmitter and receiver batteries
Stop operation and recharge the transmitter battery at the latest when the transmitterbattery is running low, the message "Charge the battery!" appears in the display, andan acoustic warning sounds.
Regularly check the battery charge, especially of the receiver battery. Do not wait until the movements of the rudder are noticeably slower. Replace dead bat­teries in a timely manner.
Always follow the manufacturer's charging instruc­tions, and charge the battery for the indicated time. Do not charge the batteries without monitoring them.
Never attempt to charge dry batteries. An acute ex­plosion hazard exists.
All batteries must be charged before each use. To pre­vent short-circuits, first plug the banana plugs of the charging cable into the charger (make sure the poles are correct). Then plug in the charging cable plugs into the sockets of the transmitter and receiver battery.
If you are not going to use your model for a while, disconnect all power sources.
Never use rechargeable or replaceable batteries with damaged, defective or different cell types; that is, a mixture of old and new cells, or cells by a different manufacturer. Combinations of old and new cells or cells from different manufacturers.
Capacity and operating time
The following applies to all power sources: The capac­ity decreases with each charge. At low temperatures, the internal resistance increases while the capacity decreases further. As a result, the battery's ability to discharge and retain power is reduced.
Frequently charging and/or using battery care pro­grams can also gradually reduce the capacity. Never­theless, check the capacity of power sources at least every 6 months, and replace them if their performance is significantly low.
Only use original Graupner rechargeable batteries!

Personal notes
Page 20
To safely operate the model, a reliable power supply is required. If the receiver voltage shown on the trans­mitter display always drops or is generally (too) low even though the linkage moves freely, the battery is full, the cross-section of the battery connecting cable is sufficient, and the transition resistance at the plug­in connections is minimal, etc., observe following:
First make sure that the battery remains fully charged when initially operating the model. Make sure that the resistance of the contacts and switches is low. Mea­sure the voltage drop over the installed switch cables under a load since even robust, new switches cause a voltage drop of up to 0.2 V. This value can be sev­eral times higher due to aging and oxidation of the contacts. In addition, constant vibration and shaking of the contacts also gradually increase the transition resistance.
Furthermore, even small servos such as a Graupner/ JR DS-281 draw stall current to 0.75 A when you stop under a load. Four of these servos in a foam airplane can hence draw up to 3 A from the on-board power supply.
Furthermore, servos connected to a 2.4 GHz receiver receive control pulses more frequently than compara­ble receivers in the classic frequency range. This af­fects the power consumption of the receiver system as well as the characteristic of many modern digital servos of maintaining the last position specified by the last control pulse until the next pulse arrives.
You should not only therefore choose a power supply that does not fail under a permanent high load and always provides sufficient voltage. To calculate the re­quired battery capacity, add at least 350 mAh for each analog servo, and at least 500 mAh for each digital servo.
Using this method, a battery with 1400 mAh rep­resents the absolute minimum for supplying power to a receiver with four analogue servos. In your calcula­tion, also include the receiver which requires about 70 mA due to its bidirectional function.
Apart from the above considerations, it is generally recommendable to connect the receiver to the power supply using two cables. As usual, connect cable "1" to the "6+B" or "12+B-" output of a GR-16 or GR­24 receiver, and cable "2" to the opposite end of the connector strip labeled "1+B-" or "11+B-" of the re­ceiver. When, for example, using a switch or voltage regulator with two power supply cables leading to the receiver. Between the cable and receiver, you can use a V or Y cable (No. 3936.11, see figure) if one or both receiver connections also need to be connected to a servo, speed controller, etc. With the double connec­tion to the switch or voltage controller, you not only reduce the risk of a cable rupture but also ensure an even power supply to the connected servos.
If you connect a separate battery to each battery connection, be sure that each of the batteries have the same rated voltage and capacity. Never connect different battery types or batteries with strongly dif­ferent charges since this can cause an effect similar to a short circuit. In such cases for safety reasons, insert voltage stabilizing elements such as the PRX­5A receiver power supplies between the batteries and receiver:
For safety reasons, never used battery boxes or dry batteries.
The voltage of the on-board power supply is graph­ically represented, when the model is in use, in the upper right side of the display so as underneath in green numerically:
If the voltage falls below the warning threshold (nor­mally 3.8 V) which can be adjusted in the "RX SERVO
TEST" display of the "SETTING & DATA VIEW" of the
"Telemetry" menu, a visual and acoustic low-voltage warnings are generated.
Attention
Thebattery level should be checked regularly. Do not wait to charge the battery until the voltage decreases enough for a warning signal to be
generated.
Tip

Charging the receiver battery
The charging cable (No. 3021) can be connected di­rectly to the receiver battery to charge it. If the battery in the model is connected by a power supply cable (No. 3046, 3934, 3934.1 or 3934.3), the battery is charged via the charging socket integrated in the switch, or a separate charging connection. The switch for the power supply cable must be set to "OFF" for charging

NiMH battery packs with 4 cells
With a traditional 4-cell pack, you can reliably operate your Graupner HoTT system providing that the above conditions are observed, and assuming that the packs have a sufficient capacity and charge.
NiMH battery packs with 5 cells
Battery packs with five cells offer greater leeway in comparison to 4-cell packs.
You should note, however, that not every servo avail­able on the market can handle the voltage from a 5-cell pack over the long term, especially when the pack is freshly charged. Some of these servos audibly "growl" when operated with a 5-pack.
Notice
You should therefore note the specifications for your servo before you choose to use a 5-cell pack.
LiFe packs with 2 cells
Given the above considerations, these cells are the best choice.
LiFe cells are also available in a hard plastic housing to protect against mechanical damage. Like lithium polymer cells, LiFe cells can be charged quickly with suitable chargers and are comparably robust.
In addition, this type of cell can undergo significantly more charging/discharging cycles than conventional LiPo batteries. The comparatively high rated voltage of 6.6 V of two cell LiFe battery packs does not pose any problems to Graupner HoTT receivers or the ser­vos, speed controllers, gyros, etc. which are approved for operation with this higher voltage.
Attention
However, practically all of the previously market­ed servos, speed controllers, gyros, etc. as well
as many which are offered today have a permis­sible operating voltage range of 4.8 to 6 V. Stabilized voltage control such as the PRX (No. 4136) is therefore needed to connect them to the receiver. Otherwise, the connected devices may quickly become damaged.
LiPo packs with 2 cells
LiPo batteries are lighter yet they offer the same ca­pacity of NiMH batteries. LiPo batteries also come in a hard plastic housing to protect against mechanical damage.
The comparatively high rated voltage of 7.4 V of two cell LiPo battery packs does not pose any problems to Graupner HoTT receivers or the servos, speed con­trollers, gyros, etc. which are approved for operation with this higher voltage.
Attention
However, practically all of the previously market-
ed servos, speed controllers, gyros, etc. as well

Lithium-ion (LiIo) and lithium polymer (LiPo) batteries require special treatment. This is true when charging, discharging, storing and all other types of handling. Observe the following specifications:
Charging Graupner LiPo/LiIo batteries
• Since Graupner|SJ GmbH is unable to monitor whether the batteries are correctly charged and discharged, all warranties are voided upon incor­rect charging or discharging.
• Only use the approved chargers with the associ­ated charging cables to charge lithium ion/lithium polymer batteries. Any alterations to the charger and/or charging cables can cause serious dam­age.
• The maximum charging capacity must be limited to a factor of 1.05 of the battery capacity.
Example: 700 mAh battery = 735 mAh max. charging capacity
• To charge and discharge lithium-ion/lithium poly­mer batteries, only use the plug-in charger in the set, or the specially designed charger/dischargers by Graupner, see under www.graupner.de.
• Make sure that the number of cells, charging cut­off and discharging cutoff voltage are set correctly. Refer to the operating instructions of your charger/ discharger.
• Under these prerequisites, Graupner lithium-ion/ lithium polymer batteries can be charged with a maximum 2 C (1 C corresponds to the cell capac­ity) charging current. Starting at a maximum 4.2 V per cell, continue charging at a constant 4.2 V per cell until the charging current falls below 0.1... 0.2 A.
• Do not charge with more than 4.20 V per cell. This would permanently damage the cell and may cause a fire.
To keep from overcharging individual cells within the pack, set the cutoff voltage to between 4.10...
4.15 V per cell in order to extend the battery life.
• The permissible temperature range for charging and discharging lithium ion/lithium polymer batter­ies is 0... +50°C.
• Batteries as well as individual cells are not toys and must be kept from children. They must there­fore be stored out of the reach of children.
• Keep batteries away from infants and small chil­dren. If a battery is swallowed, immediately con­sult a physician or go to an emergency room.
• Never place a battery in a microwave or under pressure. This may cause smoke, fire or an ex­plosion.
• Do not disassemble lithium ion/lithium polymer batteries. Disassembling a battery can cause in­ternal short-circuits. This can result in the release of gas, fire and explosion, or other problems.
• The electrolyte and electrolyte vapors within lithi­um-ion/lithium polymer batteries are hazardous to health. Avoid direct contact with electrolytes. If the electrolyte comes into contact with your skin, eyes or other body parts, use a large amount of fresh water for rinsing and then consult a doctor.
• Before each use, make sure that the batteries are in a satisfactory condition. Defective or damaged cells or batteries may not be used.
• Cells and batteries may only be used in accor­dance with the technical specifications for the spe­cific cell type.
• Batteries and cells may not be heated, burned, short-circuited or charged with excessive current or with reversed polarity.
Safety and handling instructions
for lithium-ion (LiIo) and lithium polymer (LiPo) rechargeable batteries
• If handled improperly, there is a danger of fire, ex­plosion, irritation and burns. To extinguish a fire, use a fire extinguishing blanket, CO2 extinguisher or sand.
• If the batteries overheat, proceed as follows: Disconnect the battery, and place it on a non-flam-
mable surface (such as concrete) until it cools down. Never hold the battery in your hand due to the risk of explosion.
• Batteries from parallel-connected cells, and com­binations of old and new cells, cells of different makes, sizes, capacities, manufacturers, brands or type may not be used.
• Batteries which have been installed in a device should always be removed when the device is not being used. Always turn devices off after you have finished using them to prevent battery drain­age. Dead lithium-ion/lithium polymer batteries are considered defective and may not be reused.
• Be sure to charge the batteries in a timely manner. While they are being charged, the batteries must be placed on a non-flammable, heat-resistant and non-conductive surface. Combustible or highly flammable objects are to be kept away from the charging area.
• Batteries must be monitored while they are being charged. The maximum charging current specified for the respective cell type may not be exceeded.
• You may only charge a pack of series-connected lithium-ion/lithium polymer batteries all at once as long as the voltage of the individual cells does not deviate by more than 0.05 V, or if the differences in voltage are monitored and equalized by a balanc­er connection using a balancer or equalizer during charging.
22 Safety and handling instructions for lithium-ion/lithium polymer batteries
Page 23
The 1s lithium-ion battery in the set comes with a special safety shut off. The voltage differences be­tween individual cells are therefore not balanced by means of the usual balancer plug-in connec­tion.
• If the battery heats up above 60°C while it is be­ing charged, stop charging and let the battery cool down to approximately 30°C.
• The batteries may not be modified. Do not directly solder or weld the cells.
• To avoid deformation, avoid excessive mechanical pressure.
• Make sure to observe the charging and discharg­ing instructions.
Storage
LiIo/LiPo cells should be stocked with about 50% of their nominal capacity. If the cell voltage falls below 3 V during the stocking, the lithium ion/lithium polymer cells must be recharged to 50% of the full capacity. Otherwise, the battery will die during storage and be­come useless.
Special instructions on discharging Graupner LiIo/LiPo polymer batteries:
• A continuous current of approximately 1 C does not pose a problem for Graupner lithium-ion/lithi­um polymer batteries. If the current is higher, refer to the instructions in the catalogue. Bear in mind the maximum load for the plug-in system (see the maximum discharge current indicated on the bat­tery label).
• Discharging below 2.5 V per cell will damage the cells and should therefore be avoided at all costs.
• The batteries should never be short-circuited. Short-circuits generate a very high current which heats up the cells. This causes a loss of electro­lyte, gas formation or even explosions. Graupner LiIo/LiPo batteries should therefore be kept away from and not touch conductive surfaces due to the short-circuit hazard.
• The battery's temperature during discharging should never exceed +70°C. If this occurs, make sure that the battery is sufficiently cooled, or re­duce the discharge current. The temperature can be easily checked using the infrared thermometer (No. 1963). However, the battery may not be dis­charged using the transmitter's charging socket. This socket is not designed for this purpose.
Additional instructions on handling
• The battery capacity decreases each time it is charged and discharged. Charging when the tem­perature is too high or too low can also gradually reduce the battery's capacity. After 50 cycles, the battery capacity of models is only 50-80% of that of a new battery due to the occasionally high dis­charge current and induction current of the motor, even when all charging and discharging instruc­tions have been followed.
• Batteries may only be series-connected or paral­lel-connected in exceptions since the cell capacity and charge can differ. The battery packs that we supply are therefore preferable.
• The connections of lithium ion/lithium polymer batteries are not as robust as other batteries. This holds true particularly for the plus pole connection. The connections can easily break.
Cells connection
Attention
Direct soldering on the battery cells is impermis­sible. The heat from direct soldering can damage battery components such as the separator or
isolator.
Battery connections should only be created by spot welding in the factory. If the cable is missing or sev­ered, have it repaired professionally by the manufac­turer or dealer.
Replacing individual battery cells
Attention
Individually battery cells may only be exchanged by the manufacturer or dealer and not by the user.
Do not use damaged cells
Damaged cells may not be used. Indications of damaged cells include damaged hous-
ing packaging, deformed cells, the smell of electrolyte or leaking electrolyte. The battery may not be used in these cases.
Damaged or useless cells are considered hazardous waste and must be disposed of properly.
Contact with liquids
Batteries may not be immersed in liquid such astap water, sea water or beverages. Avoid all contact with liquids of any kind.

Definition of terms
Control function, control, function input, control channel, mixer, switch, control and logical switch
To make it easier to use the Part 2 of the manual, we offer a few definitions of terms that appear repeatedly in the manual.
Control function
A control function is understood as the signal for a specific control function independent of the signal within the transmitter. In fixed-wing models set e.g. the control signals would be throttle, rudder or aileron; in helicopter models, these would be e.g. pitch, roll or nick.
The signal of a control function can be transmitted directly into one control channel or through a mixer to several control channels. A typical example of the latter are separate aileron servos, or the use of two roll or elevation servos in helicopters. The control function includes the influence of the mechanical control path on the corresponding servo. This can be spread or concentrated and modified from linear to highly ex­ponential.
Controls
Controls are the control elements on the transmitter that are activated directly by the pilot that control the connected servos, speed controllers, etc. on the re­ceiver. These include:
• The two control sticks for control functions 1 to 4, including the related trims. These four functions in all the six model types (vehicle, boat, copter, helicopter, motor airplane and glider) can be ex­changed using the mode setting in the software, such as throttle left or right. Throttle/brake or throt­tle/pitch left or right. The control stick function for Throttle/brake flap control for fixed-wing models or throttle/pitch control in helicopters is frequently identified as the THR control (channel 1).
• the four proportional dials (DV1 … DV4)
• The two side proportional rotary controls SL1 and SL2 mounted on the bottom.
• Switches S1 … S8
• the INC/DEC buttons DT1 and DT2
With the type DV and SL proportional controls as well as the INC/DEC buttons, the servos directly follow the control position, whereas only a two or three-stage adjustment is possible with a switch.
The assignment of the controls and switches to the servos 5 …12 is freely programmable.
Function input
This is an imaginary point in the signal flow and should not be confused with the control connection on the printed circuit board. The selected control mode and the settings "TX OUT SET" line of the ""CTL Set"" sub-menu (transmitter setting) of the base menu influ­ence the sequence beyond the physical connecting points and this can generate differences between the number of function inputs and the number of subse­quent control channels.
Control channel
From the point at which a signal contains all control information necessary for a particular servo, whether directly from the control or indirectly via a mixer, the term control channel is used.
For example, the "aileron" control function of a fixed­wing model for the model type "2AILE" is divided into control channels for the left and right aileron. Analo­gously,the "Roll" control function for the helicopter model "3Sv(2Roll)" governs the controlchannels for both the left and right roll servo.
This signal is only influenced by the settings made in the sub-menus "E.P.A" (servo path/servo limit), "REV/
SUB" (servo direction reverse/delay) and "Sub-Trim"
(servo middle and neutral position) to adjust the ser­vo, and possibly the settings in the sub-menu "Out.
Swap" (transmitter output) and is then transmitted by
the transmitter through the RF module. Once it arrives in the receiver, this signal may be modified by settings saved in the "Telemetry" menu, after which it controls the associated servo.
Mixer
The transmitter program contains a variety of mixing functions. These allow a control function to influence several control channels and as final result several servos or even many control functions to influence the same one servo.
In this context, you can refer to the numerous mixing functions.
Switch
The series of toggle switches S1 … S8 can also be in­cluded in the control programming. The switches are however generally also intended to switch program options such as to start and stop the timers, turn mix­ers on and off, as trainer switches etc. Each of the switches can be assigned any number of functions.
Related examples are listed in the manual.
Control switch
Since it is occasionally practical to automatically switch a timer or a function on or off when a control is in a specific position (a stopwatch turns on/off to measure engine operating times), the program for the mz-24 HoTT Pro transmitter also allows you to pro­gram control switches.
24 Definition of terms
Page 25
With these program switches, all you have to do is specify the switching point along the control path in the direction of switching. More detailed information are easily available in the paragraph "Controls and switches assignment".
Logical switch
Through this option two switches, controls and/or logical switches or the favorite combination of them, can be interconnected in an "AND" or "OR" switch. A total amount of 8 logical switches "L1 … L8" can be programmed, see description in the "Logical switch" menu.
25
Definition of terms
Page 26
Control and switch assignment
Basic procedure
In many places in the program, you can actuate a control function with a freely selectable control (ST 1 … 4, DV1 … D4, DT1 and DT2, SL1 and SL2), switch (S1 … 8), or switch between settings with a switch (S1 … 8), control or logical switch (see below). In both cases, multiple assignments are always possible. (The distinction between a control and switch is explained in the section "Definition of terms").
Notice
It should be noted however that incorrect re­sponses may arise from functional overlaps such
as using the same physical switch as a switch to switch between Phase switch and as a control for Phase trimming. Change also your switch assignment.
Since the same method is used to assign the controls, switches control and logical switches in all relevant menus, the basic procedure will be explained at this point which will allow you to focus on the specifics in the detailed menu descriptions.
Control and switch assignment
In the sub-menu "CTL Set" (control and switch as­signment) you can …
… assign transmitter inputs 1 … 12 to operate ser­vos of the mz-24 HoTT Pro transmitter as well as any control stick (ST1 … ST4) and controls identified as "DVx", "SLx" or "DTx", or any switch identified as "S1 … S8".
The following window appears in the display af­ter touching the corresponding button, such as the NONE button to the right of "CH 5" in the second page of the display of this menu, with a finger or the provide stylus, and the following window will appear:
Actuate the desired control (control stick 1 … 4, DV1 … DV4, SL1 … SL2, or DT1 … DT2) or switch (S1 … S8), such as the right proportional rotary control SL1:
Note
The controls are only recognized after a specific path. Therefore move the control to the left or
right, forward or backward until the assignment appears on the display. If the length of travel is insuffi­cient, move the control in the opposite direction.
Deleting controls or switches
After the switching or control assignment has been activated as described, touch the CLR button.

Control or switch assignment interruption
After the switching or control assignment has been activated as described, touch the N button.
Notice
In few menu positions you can assign only phys­ical controls or switches, that is the reason why in the pop-up windows that appear in those posi-
tions the LOGIC button is not available, for example:
This is not an error.

Assigning logical switch or control
• Switch assignment
The places in the program where a switch, a logical control or switch can be assigned are marked with "CTL". So as for example as marked with a red cir­cle in the penultimate line of the following picture of the Dual Rate / Expo displays:
As soon as you tap on NONE , on the right near CTL …
touch
... the window in the display will ...
... appear. Actuate the desired switch, for example the front left 3-way switch S5:
Thus completes the assignation of the switch for this menu.
• Switch setup
In other menus, in which the switches can be as­signed, for example the "PHASE" menu, …
... an accessory display will appear immediately af­ter the switch assignation.
Completely independently from the yellow arrow, which only indicates the actual position, you can confirm in this display by touching the related but­ton, in which position di selected phase should be "ON", for example:
It has to be logically matched with the other switch positions.
Notice
The phase 1, the "normal phase", is then al­ways active when none of the assigned phase switch is on the "ON" position.
If you choose the 2-stage switch SW 6 instead of the 3-stage switch SW 1, the display appears as follows:
Select the desired switching direction as above.

The yellow arrow to the right of the bar diagram illustrates the current control position which can be accepted by touching the ENT button as the switching point in the value field to the right of "POS". Reverse the switching direction by touch­ing REV in the line "DIR(ection)".
In the "MODE" line, the switching function of the control switch can be changed from on/off like a 2-stage switch to the switching behavior of a 3-stage switch.
Notice
In this case, be sure to specify a switching po­sition that is not "000". Otherwise, you risk
switching continuously back-and-forth be­tween the two switching states while the relevant control is in the middle control position.
• Assigning logical switch
After the switching or control assignment has been activated as described at the beginning of this sec­tion, touch the LOGIC button:
touch
In the new window appears a list with the eight logical switches "L1 ... L8" so as 8 inverted logi­cal switches.
As soon as you tap on the desired switch, it will be assumed in the output menu, for example:
Notice
Therefore do not forget to program the related selected logical switch in the "Logical sw" sub-menu!
Tips
Through the logical switches, see sub-menu "Logi-
cal sw", you can logically interconnect two switch-
es and/or also control switch in a "AND" or "OR" switch.. A total amount of 8 logical switches "L1 ... L8" (so as 8 accessory logical switches with reversed switch direction) are available.
The result of one of these logical switch functions can also be used as switch function in another logi­cal switch. For more specific details, see the related menu.
• All of these switches can be given multiple assign­ments. Make sure that you do not accidentally as­sign competing functions to a switch. It is recom­mendable to write down the switching functions.
Practical examples:
• Turning an on-board glow plug heater on and offwhen a idling switching pointfor the THR con­trol stick is exceeded or undershot. The switch for the glow plug heater is controlled at the transmitter by a mixer.
• Automatically turning the stopwatch on and off to measure the actual flight time of a helicopter by means of a control switch on the throttle limiter.
• Automatically turning off the mixer "AILE RUDD" when the brake flap extends to adapt the landing position of the model to the ground contour when landing on a slope without affecting the direction of flight by rudders which are otherwise involved.

So that when you are programming you will only have to concern yourself with the related menus.
Connection notices
For vehicle and boat models there are basically four different ways of assigning the control functions for­ward/backward and left/right of both control sticks. The options that are chosen depend on the individ­ual preferences of the model pilot. The compatibility with the Control modes 1 … 4 ways is however rec­ommended, connect the control function 1 with the forward/backward function and the control function 4 with the direction function:
Also for copters there are basically four different ways of assigning the four control functions of roll, nick, yaw and throttle/pitch of both sticks. The options that are chosen depend on the individual preferences of the model pilot. The compatibility with the Control
modes 1 … 4 ways is however recommended to take
the following occupation as example:

HoTT synchronization methods setting
As already mentioned in the paragraph "Starting up the
receiver", if both receiver and RF module are switched
off each preferred of the total 30 model memories of the mz-24 HoTT Pro transmitter can be switched from the standard memory specific HoTT-Synchronization to transmitter specific and vice-versa. It is possible to recognize the model memory with active HoTT-syn­chronization method from the yellow "G" which is dis­played on the right near the selection button which is near the model name.
WITHOUT "G" on the right near the button = memory specific bound
WITH "G" on the right near the button = transmitter spe­cific (global) bound
In the following representation the model memories 1, 2 and 3 are left as example on memory specific HoTT-Synchronization and the memories 4, 5 and 6 have been switched to transmitter specific HoTT-Syn­chronisation.
Switching the HoTT-Synchronization
Switch the RF module of your transmitter off. Tap on the actually in use model memory, for example
model memory 3:
Touch
The color of the field switches from black to blue:
Now tap on the model type icon, ...
Touch
... here it will appear a selection window, where the se­lection buttons are always indicated with the descrip­tion of the method, through which you can switch. In this example from memory specific to transmitter spe­cific. Subsequently the button is actually described with the synonym "GLOBAL" for transmitter specific:
Touch NO to terminate the procedure. Touch­ing  GLOBAL switches the selected model memory to "global", that means transmitter specific HoTT-Syn­chronization:
39
Base menu - Model selection
Page 40
If you want to switch a model memory, which is actu­ally set to GLOBAL, to model specific HoTT-Synchro­nization, then the selection button will appear with the description MODEL:
Touch NO to terminate the procedure. Touch­ing MODEL switches the selected model memory back to model memory specific HoTT-Synchroniza­tion:
• As conclusion of the switching process for one or more model memories all the involved receivers must be bound again.
• "GLOBAL", then transmitter specific, bound re­ceivers react to the signals of all of the global bound model memories of "their" transmitter, this explains why for safety reasons a model memory change is only possible after switching off the re­ceiver system!
CAUTION
A receiver system, switched on acci­dentally after a model memory change,
reacts to every control movements of the model memory bound in global mode as soon as a valid signal is emitted from "its" transmitter.
• "MODEL" specific bound receivers react exclu­sively to the signal coming from the specifically assigned model memory. An accidental use thor­ough a non specifically assigned model memory is NOT possible. A receiver which has eventually been switched on after a model memory change will pass to the Fail-safe mode during all the time in which the aforementioned situation lasts.
Tip
Information about HoTT-Synchronisation after copying or exporting/importing a model memory can be found in the related following section.

The previous section described the basic manual programming of a fixed-wing model. In the following, the assistant-controlled programming of a helicopter model will be described. As the manual programming, also the assisted programming follows always a pre­defined program procedure.
Tip
Some of the following described sub-menus offer theo­retically the possibility of phase-specific settings. Each one indicated on the upper left side by the green colored phase name "PHASE 1", for example:
Because within the assisted programming only settings in the "Phase 1" (the normal phase) are possible, in this context it will not be told much more about "phase spe­cific settings". More about this point is explained in the description of the single menu point.
As described under NEW in the section "Model se-
lection", to set up a new model, select a free model
memory or model memory that has already been as­signed but is no longer required.

Since at this juncture we want to program a "helicop­ter model", touch the Heli button:
Touch
After selecting the basic model type, the following ap­pears in the display...
"Swashplate type"
... in which you can specify the number of swashplate servos by touching the corresponding selection field:
• "1 Servo"
You are using a flybar system, or the swashplate is tilted by a roll and nick servo. One separate servo is used for the pitch control.
(Since helicopter models with only one pitch servo that have three swashplate servos for pitch, nick and roll also operate without a mix of functions in the transmitter as is usually the case with flybar
systems, the menu item "Swash", page , normally does not appear on the multifunction menu.)
• "2 Servo"
The swashplate isshifted axially for the pitch con­trol by means of two roll servos; the nick control isdecoupled by means of a mechanical compen­sation rocker.
• "3Sv (2Roll)"
Symmetrical three-point control of the swash­plate by means of three articulations pointsoffset by 120°, by means of which one nick servo (front or rear) and two roll servos (to the left and right side) are connected. All of the three servos of the swashplate shift axially for pitch control.
• "3Sv (140)"
Asymmetrical three-point control of the swash­plate by means of three articulations pointsoffset, by means of which one nick servo (rear)and two roll servos (to the left side and right front) are con­nected. All of the three servos of the swashplate shift axially for pitch control.

• The possibility to reverse the direction of the servos connected to the output 6 (C6) in a helicopter model and the output 1 (C1) in the other types is only offered to match with the different building cases. Otherwise the switch­on warning will react not properly. For this rea­son a change in the value field is only possible after confirming the "SURE?" warning.
• Independent of trim controls and any mix settings, the neutral position can be shifted around ±125% within the maximum servo travel of ±150%. The servo is always adjusted directly independent of all other trim and mix settings.
Note that if the neu­tral position is ad­justed strongly, ser­vo travel on one side may be restricted since the total travel is limited to ±150% for electronic and mechanical reasons.
Tap on the WIZ. button at the top left to go to the next option ...
• "3Sv (2Nick)"
Symmetrical three-point axis as before, but rotat­ed 90°; one roll servoon the side, and twonick servos, front and rear.
• "4Sv (90)"
Four-point control of the swashplateby means of two roll servos and two nick servos.
Directly after you make your swash plate selection, the following display appears ...
"Propulsion type"
... where you specify whether your helicopter is driven by an electric motor or ICE engine:
After you select the propulsion mode, the assistant takes you to the first model-dependent settings in the following display...
"REV/SUB" (Servo reverse/Servo sub trim)

Once all you have adjusted all of your servos, touch the WIZ. button at the top left to switch to the next adjustment phase:
"D/R,EXP"
The dual rate/expo function allows you to switch or influence the control deflections and characteristics for the control functions of roll, nick and tail rotor, i.e. control functions 2 … 4 through switch.
Dual Rate acts, as the control setting in the sub­menu "Ctl.SET", directly on the related Control func- tion, independently from the fact that the function is associated to a single servo or i actuated thorough a complex mixer or coupling function by many different servos.
The control deflections can be set for each switch position between 0 and 125% of the normal control travel.
EXP allows a more sensitive control of the model in the central position of the respective control function (roll, nick and tail rotor) for values greater than 0% without having to do without the complete deflection in the end position of the control stick.
Conversely, the effect of the control around neutral position increases for values less than 0% and de­creases in the direction of the full deflection. The pro­gression can be set from -100% to +100%; 0% cor­responds to the normal linear control characteristic.
The EXP setting always acts directly on the corre­sponding control function independent of whether it affects the individual servo or several servos by means of complex mixing and coupling functions.
By default, the dual rate and/or expo values are set for each control side. After switching the option "SYM" from OFF to …
Touch
... to ON, a symmetrical, that is joint, setting of both control sides is possible.
In the graphic of the display, the curve characteristics are shown directly.
Tip
After having completed the program assisted model pro­gramming and the setting of the phases in the "PHASE" sub-menu of the functions menu all the options con­tained in the Dual rate/Expo phase specific menus can be programmed.

Tip
After having completed the program assisted model programming and the setting of the phases in the "PHASE" sub-menu of the functions phase specific menus can be programmed.
Basic operating steps
• Button ST OFF / ST ON
Touch this button to turn the graphic and nu­meric display of the control stick position on and off, for example:
With the control element (gas/pitch control stick), a vertical green line is moved synchro­nously in the graph between the two endpoints "L" and "H". The momentary control stick po­sition is also displayed numerically in the line "IN"(put) (-100 % to +100 %). The intersection of this line with the curve is identified as "OUT­"(put) and can be varied at the support points between -125% and +125%. The control sig­nal which is changed in this way then affects all of the following mixing and coupling functions.
ENT button
Touch the button at the bottom right of the dis­play to set up to 5 additional points between the two endpoints "L" and "H".
In the following example, the control stick is ex­actly between the middle and end of its path, at +50% of the control path, and generates an output signal that is also +50% due to the lin­ear characteristic.

Once the support point number appears along with the associated value in the line "POINT" and the point is red (see the screen-shot be­low), you can delete it by touching the ENT button, for example:
Touch
Changing the support point value
X-axis button (X-axis)
Activate this function by touching the button at the bottom edge of the display.
You can then move an active (red) point to the right with the + button, and to the left with the – button, for example:
Touch the X-axis button again to deactivate the function.
Tips
• If you move the red pointhorizontally away from thecurrentcontrol position, the point becomesgreen after a short while, and a "?" appears in the Point line. This question mark does not relate to the point which has been moved but rather indicates that another point can be set at the current control position.
• Remember that the percentages in the "IN"(put) and "OUT"(put) line always refer to the momentary position of the control stick and not to the position of the point.
Y-axis button (Y-axis) Activate this function by touching the button
at the bottom edge of the display. You can then move an active (red) point to
the top with the + button, and to the bottom with the – button, for example:
Touch the Y-axis button again to deactivate the function.
Between the two endpoints "L" and "H", up to 5 additional support points can be set, and the distance between neighboring support points may not be less than approximately 25%.
Move the control stick. As long as a ? is next to the "POINT", you can set the next support point by touching the ENT button. At the same time, the "?" is replaced with a number:
The sequence in which the up to 5 points be­tween the end points "L" and "H" are generat­ed does not matter since the support points are automatically renumbered sequentially from left to right after one support point is set or delet­ed, for example:
Deleting a support point
In order to delete the set support points 1 to 5, move the vertical line with the control stick next to the relevant support point.

The throttle curve can be specified by up to 7 points, the so-called support points, along the entire control stick travel:
Support points can be set, changed and deleted in the same manner as described in the previous sec­tion, "Pitch curve". First specify the throttle curve us­ing three points, that is, the two end points "L" and "H", as well as the other set point "1" in the control center in order to harmonize the motor performance curve with the pitch curve.
Tip
The value shown in the top left "throttle limit" line indi­cates basically the status or the position of the throttle limit.

• "Gyro Suppression" line
Notice
This option maynormally not be used for cur­rent standard gyro systems. You therefore
need to consult your gyro setting instructions since otherwise you may make it impossible to fly your helicopter. Nonetheless, this sub-menu was re­tained to satisfy all requirements and conventions.
This option can influence the effect of the gyro sensor (gyroscope) as the tail rotor control stick is moved, assuming that a gyro system is used in which the gyro's effect can be set by the transmit­ter using an additional channel, channel 7 in the Graupner remote-control system. The gyro sup- pression reduces the gyro's effect in a linear man­ner in proportion to the deflection of the tail rotor control stick corresponding to the set value. If the gyro has not been suppressed (at a value of 0%), the gyro's effect remains independent of the con­trol stick deflection.
The gyro's effect can however be additionally var­ied smoothly between a minimum and maximum using a control assigned in the "Gyro" line in the "CTL Set" menu, for example with one of the pro­portional dials DVx. More on this subject can be found in the section "Gyro/governor".
• "Gyro Gain" line
Most of the current gyro systems can be adjust­ed for a smooth, proportional effect; you can also choose between two different modes of action by the transmitter.
If the gyro that you are using also has one of these options, the alternative offset setting enables both the normal gyro gain and "heading lock mode" as well as flying with maximum stabilization in normal, slow fights within this selected mode, and reduc­ing the gyro gain in fast roundtrips and aerobatics.
Values up to ±125% are possible, for example:
Based on these phase specific settings (offset) the gyro gain can also be proportionally varied with a control assigned in the line "C7" in the sub-menu "CTL Set", as for example the proportional dial DVx.
Attention
• You therefore need to consult your gyro setting instructions since otherwise you may make it impossible to fly your helicop­ter.
• Note that the offset values enteredin this optionas well as in the line "CH 7" of the sub-menu "CTL Set" add up! For the sake of clarity, make sure to only enter or change an offset value in one of the two options.
• "Governor ACT" line
In contrast to speed controllers that only regulate performance like a carburetor, governors maintain a constant speed in the system that they are mon­itoring by independently regulating the provided output. Like the cruise control in cars, a governor controls in case of ice engine helicopter the throt­tle servo in the same way as the speed controller of an electric motor helicopter. Governors there-
fore only require a speed setting and not a classic throttle curve. A deviation from the set speed oc-
curs when the required output exceeds the maxi­mum available output.
To change the current value, touch the desired button in the "Governor ACR" line. The display switches from "OFF" to "ON" and vice versa, for example:
• "Governor RATE" line
In the "GOVERNOR" line, in case you have switched on the function "Governor at CH8". In the "Governor RATE" line, enter the appropriate offset value for the desired rotor speed. The value to be set depends on the governor that is used as well as the desired target speed, and can of course be varied for specific phases, for example:

With a control assigned in the "C8" line of the sub­menu "CTL Set", for example the proportional dial DVx, this value can also be proportionally varied.

Page 63
Notice
In contrast to the "CTL Set" sub-menu, all the settings of this sub-menu refer to the relevant
servoindependent of where the control signal for the servo comes from , i.e., either directly fromthe con­trol element orfrom mix functions.
Example
The rudder servo of a model is directly controlled by the rudder control stick and also through an accessory "Ai­leron Rudder" mixer. For model-specific reasons, this servo can only follow a maximum servo travel of 100% since for example the rudder would contact the elevator if the allowed mechanical travel was more than 100%.
As long as only the rudder is used, this is not a problem. It becomes a problem, however, if the signals add up to a total travel of more than 100% when simultaneously using the rudder and the aileron. The linkages and ser­vos can be subject to an extreme load...
To prevent this, the path of the relevant servo has to be limited individually. In the case of the rudder servos used here as an example, this would be slightly less than 100% since we are assuming that the rudder is already traveling 100%.

Setting of the servo direction and neutral position
Servo direction and neutral position
In both these displays in the left column can be set the direction of each servo and in the right column the related neutral position.
Notices
• First of all start by setting basically the direc­tion in which the servos have to move before you start setting other parameters!
• The numbers for the servos refer to the servos connected to the corresponding receiver out­putsproviding that thetransmitter and receiv­er outputs have not been switched. A change in the control mode therefore does not influ­ence the numbering of the servos.
1. Setting the servo direction
With this option, the direction of servo rotation is adapted to the specifics in the particular model so that, when the control linkages and articulations are installed, the servo's rotational direction does not have to be considered.
The direction of travel is reversed by touch­ing the corresponding value fields labeled NOR and REV, such as:
As soon as the travel direction of CH6 in a helicop­ter model type or CH1 in the other model types is going to be changed, a warning will be displayed:
Touch NO to terminate the procedure. Touch YES to confirm the procedure which changes the direc­tion of travel of the servo connected to CH1 or CH
6.
64 Base menu - Servo reverse/Servo center
Page 65
Notice
In no case you should use the possibility of the servo reverse of the channel 6 for helicopters and
channel 1 for other model types to reverse the direction in which the related control stick works, only use this possibility for situation adaptation. Because the switch-on warning "CH1-Pos" as the "Thr.HOLD" func­tion do not follow this kind of reverse control direction. To reverse the control direction use exclusively the pos­sibility offered by the "Pitch curve" menu for helicopters models and "Throttle curve" for all the other model types.
2. Setting of the neutral position
The servo middle position is for adapting servos that are not standard (servo middle position with a pulse length of 1.5 ms or 1500 μs ) as well as for minor adaptations, for example fine adjustment to the neutral position of control surfaces on the model.
Independent of trim controls and any mix settings, the neutral position can be shifted around ±125% within the maximum servo travel of ±150%. The servo is always adjusted directly independent of all other trim and mix settings.
Notice
Note that if the neu­tral position is ad-
justed strongly, ser­vo travel on one side may be restricted since the total travel is limited to ±150% for electronic and mechani­cal reasons.
Notice

The speed controller or the throttle servo only as­sumes the set position if a freely selectable switch has been activated ...
• By moving the selected switch to the ON posi­tion the speed controller or the governor will be reduced to the value which has been input in the "SET" line, independently from the actual position of the throttle/brake or throttle/pitch control stick.
... and in models with ICE engine also this passage must be performed:
• If the set percentage in the "SET" line is less than the current servo position, that is, the currentservo position represented by the green arrow to the left of the bar graphic is above the switching threshold represented by the red arrow in the bar graphic, the speed controller reduces the motor speed, or the throttle servo closes the carburetor as speci­fied in the "SET" line once the servo position falls below the switching threshold of -66% when the switch is in the ON position.
• If the control stick position, represented by the green arrow on the left of the bar graphic, is actu­ally under the red arrow on the right of the graph­ic, the speed controller or governor increases the motor speed or the throttle servo opens the car­buretor as specified in the "SET" line, after moving the switch to the ON position as soon as the con­trol stick moves over +66% or under -66% of the switch threshold if the motor OFF position is set in the plus side.
• In this motor OFF position, the speed controller or the governor are disabled until the selected switch is not moved again.
The preset value of the field in the "SET" line of the idle or "motor off" position is -100% of the throttle/ brake or throttle/pitch control stick travel:

BIND ON/OFF
To establish a connection with the transmitter, the Graupner HoTT receiver must first be "bound" to at least one model memory in "its" Graupner HoTT transmitter. This process is generally called "binding" and it can be repeated all the times it is needed. This binding of a receiver is normally performed always model memory specifically, but it can be changed in every moment to transmitter specific, for every mod­el memory of the same transmitter in the sub-menu "Model selection". A detailed description of this pro­cess is available in the "HoTT synchronization meth-
ods setting" section:
MODEL memory specific synchronized receivers react exclusively to the signal coming from the specifically assigned model memory. An acciden­tal use thorough another non specifically assigned model memory is then basically NOT possible. A receiver which has eventually been switched on will pass to the Fail-safe mode during all the time in which the aforementioned situation lasts.
GLOBAL, transmitter specific, synchronized re­ceivers react to the signals of all of the global bound model memories of "their" transmitter, this explains why for safety reasons a model memory change is only possible after switching off the re­ceiver system!
WARNING
A receiver system, switched on acci­dentally after a model memory change,
reacts to every control movements of the model memory bound in global mode as soon as a valid signal is emitted from "its" transmitter.
• The HoTT synchronization process of a copied or imported model memory depends on many differ­ent factors. More about this point can be found on page 54 and 58.
Notices
• As conclusion of the switching process for one or more model memories all the involved receivers must be bound again.
• When binding, make sure that the transmit­ter antenna is always far enough away from the receiver antenna. Maintain a distance of 1 meter to be on the safe side. Otherwise, you risk endangering the connection with the feedback channel and causing malfunctions.
• Make sure that the receiver power supply is correct. If the power supply is too low, the receiver LEDs will react, as described in the included receiver manual, in response to your binding attempt, but the HoTT synchroniza­tion will not be performed.
• When binding to other receivers, note that other switched-on receivers already bound to the transmitter (and hence not directly af­fected by the binding process) enter fail safe mode while the transmitter is binding.

Page 69
Binding several receivers per model
If desired, several receivers per model can be bound. In the related programs of the mz-24 HoTT Pro re­ceivers, you can directly manage up to two receivers bound to each active model memory and use a menu to distribute the 12 transmitter control channels be­tween the two receivers (see below in this section). First bind the two receivers one by one as described below.
During subsequent operation, only the receiver es­tablishes a telemetry link to the transmitter that was either last bound to the active model memory, or was selected in the "RECEIVER SELECT" line inthe "Te­lemetry", for example:
Telemetry sensors eventually installed in the model have to be connected to this receiver, because the transmitter will indicate only the values coming from the back channel of the receiver selected in this line. The second receiver (and all other receivers) run inde­pendently at the same time in slave mode.
Tip
• To RX2 can only be bound a receiver if there is al­ready a bound receiver on RX1.
• If for any reason the binding of the RX2 should fall, also the RX1 will be set to OFF . The binding of a receiver to RX1 has to be renewed firstly and of course before a new binding can be attempted to RX2.
"Binding"transmitter and receiver
Turn off the power supply to your receiver at this time(at the latest).
• GR-16 and GR-24 and similar receivers
The red LED flashes on the receiver. Hold down the SET button on the receiver until, af-
ter about 3 seconds, the flashing red LED flashes red/green for around 3 seconds. Then release the SET button on the receiver. As long as the LED is flashing red/green, the receiver is in binding mode.
Within this 3 second window, start binding the re­ceiver to the current model memory by touching the RX1 button in the "BIND ON/OFF" line with a finger or the provided stylus, for example.
Touch
The writing in the button will change from "OFF" to "CHK":
Binding is complete once (within a period of ap­proximately 10 seconds) the flashing red receiver LED shines green continuously. Your model mem­ory/receiver combination is now operable. At the same time, instead of CHK, an abbreviation of the receiver type such as 12CH appears for the re­ceiver GR-24 HoTT receiver which comes stan­dard:
At the same time, RF transmission is turned on (see the line "RF ON/OFF" in the following display).
If the red receiver LED continues to flash for more than 10 seconds, the binding process was unsuc­cessful. At the same time, OFF appears again in the line "BIND ON/OFF". Change the positions of the associated antennas and try the entire proce­dure again.
• GR-12L and similar receivers
The red LED on the receiver shines. Hold down the SET button on the receiver until,
after about 3 seconds, the red LED goes dark for around 3 seconds. Then release the SET button on

the receiver. As long as the LED is dark, the receiv­er is in binding mode.
As described above, within this 3 second win­dow, start binding the receiver to the current mod­el memory by touching one of the two buttons in the "BIND ON/OFF" line with a finger or the provid­ed stylus, for example.
Binding has been successful if the receiver LED remains dark and the receiver display switches to
6CH .
If the red receiver LED shines red again, the bind­ing process was unsuccessful. At the same time,
OFF appears again in the line "BIND ON/OFF".
Change the positions of the associated antennas and try the entire procedure again.
Out.Swap (receiver output) As mentioned in the introduction to the section "Bind-
ing receivers", the mz-24 HoTT Pro transmitter allow you use this menu item to distribute the transmitter control channels within a receiver as desired, and you can also distribute the 12 receiver control channels to the two receivers as preferred. This distribution will be termed mapping or channel mapping in the following.
Touch the receiver (such as "RX1") to be mapped in the line Out.Swap:

• If there is no other reaction than a "beep", the RF module is switched off. Switch the RF module on and repeat the process.
• If a pop-up display appears with the warning text ...
... the RF module of your transmitter is switched on but there is no connection with the receiver. Then switch the receiver system on and/or bind correct­ly the receiver and repeat the process.
Channel assignment within a receiver
Like the channel mapping described in "Channel
Mapping" (also termed "channel mapping" in the "Te-
lemetry" menu), you can easily distribute transmitter
control channels at the receiver inputs to the outputs, or servo connections, of the selected receiver, for ex­ample:
Touch
After selecting the desired output the respective servo output of the receiver to map by tapping on the relat­ed channel button, the color of the selected button changes from black to blue:
Repeatedly touch + or – to select the desired input channel related Transmitter output (see page ), for ex- ample:
Touch the RES button to reset a changed output to the default mapping.
The value modified by touching one of the three later­al +, RES or – buttons will be automatically trans­mitted to the related receiver.
Use the same procedure to switch other control chan­nel/receiver output combinations.
Notice
If for example you entered "2AILE" in the basic settings for a model, the transmitter assigns con-
trol function 2 (aileron) to control channels 2+5 for the left and right aileron. The corresponding transmitter outputs (= receiver inputs) to be mapped would in this case be channels 2+5 (see the examples below).
70 Base menu - Transmitter setting
Page 71
Touch the BACK button at the top left of the display to return to the "Transmitter setting" sub-menu.
Examples
• On a large model, you want to control each aileron flap using two or more servos:
Assign the same input (control channel) to the rele­vant outputs (servo connections). In this case, as­sign one of the two default aileron control channels 2 + 5 as an input depending on the left or right wing.
• On a large model, you want to control the rudder using two or more servos:
Assign the same input (control channel) to the rele­vant outputs (servo connections). In this case, de­fault rudder channel 4.
Notices
• The maximum number of available lines (out­puts) corresponds to the maximum number of servos that can be connected to each receiv­er.
• You can use the "Transmitter output" op­tion, of the mz-24 HoTT Pro transmitter to switch the transmitter control function as de­sired, or assignthe same control function to several outputs. For the sake of clarity, it is strongly recommended to only use one of the two options.
Assigning one channel to tworeceivers
As mentioned above, you can use the "receiver out­put" option to distribute the 12 control channels of the mz-24 HoTT Pro transmitterto two receivers as desired.
The numbering of the outputs (servo connections)and the maximum number of available lines (outputs)cor­responds to the maximum number of servos that can be connected to the respective receivers. Follow the same procedure as above.
RF ON/OFF
In this line, you can manually turn the transmitter's RF transmission off and back while the transmitter is cur­rently turned on, For example to be able to chance model memory or to change model type .
Notice
The next time the transmitter is turned on or a model is switched, theOFF setting is reversed.
To manually turn the high-frequency transmis­sion of your transmitter on or off, touch the corre­sponding button in the "RF ON/OFF" line:

RANGE TEST
The integrated range test reduces the transmitter out­put so that you can perform a function test at a dis­tance of less the 100 m.
Perform the range test for the Graupner-HoTT system according to the following instructions. It is useful to have an assistant to help you with the range test.
1. Install the receiver(s) already bound to the trans­mitter into the model as described.
2. Switch the transmitter on and wait until the receiv­er/s indicate/s a correct function connection. You are now able to monitor servo movements.
71
Base menu - Transmitter setting
Page 72
3. Place the model on a flat surface (concrete, mowed lawn or ground) so that the receiver antennas are at least 15 cm above the ground. It may therefore be necessary to place a support underneath the model during the test.
4. Hold the transmitter at hip level at a slight distance from your body. Do not point the antenna direct­ly at the model; rotate and/or bend the transmitter antenna so that is it is approximately at a right an­gle to the model.
5. Activate the range test mode by touching the but­ton to the right of "RANGE TEST" with a finger or the provided stylus, ...
Touch
... whereupon a safety query appears:
Touch NO to terminate the procedure. Touch YES to start the range test.
When the range test starts, the outputof the trans­mitter decreases significantly. At the same time, the illuminated company name Graupner below the two middle proportional dials starts to flash.
Simultaneously, the time display in the transmit­ter display starts to count backwards and emits 2 beeps every 2 seconds.
5seconds before the range test ends, 3 beeps ev­ery second. After the 99-second range test, the transmitter switches back to full output, and the Graupner logo shines continuously.
6. During this time, move away from the model, and also move the transmitter's control elements. If you detect an interruption in the link within a range of about 50m at any time, attempt to reproduce it.
7. If the model has a motor, turn it on to also check interference resistance.
8. Move further away from the model until it does not respond perfectly.
9. At this location, wait for the remainder of the test period with the still operable model. The mod­el should still react properly to control commands once the range test is finished. If this is not 100% the case, do not use the system and contact your Service at Graupner/SJ GmbH.
10. Perform a range test before each flight, and simu­late all servo movements that could occur during the flight. In order to guarantee a safe model oper­ation, the range must always be at least 50m on the ground.
WARNING
Never start a range test on the transmit­terduring normal model operation!
DSC OUTPUT
To set the modulation of your transmitter at the DNC output, touch the button with the current setting in the "DSC Output" line (repeatedly if necessary) un­til the desired modulation appears. Four types of modulation are available in this sequence: "PPM10", "PPM16", "PPM18" and "PPM24":
Touch
The selected modulation primarily influences the band width and the number of available control channels at this DSC socket and hence a flight simulator or train­er system connected to this socket. If "PPM10" is selected, the channels are 1 … 5; with "PPM16", the channels are 1 … 8, with "PPM18", the channels are 1 … 9, and with "PPM24", the control channels are 1 … 12.

Fail Safe
In comparison to classic PPM technology, the sys­tem-related greater reliability of the HoTT system is because the microprocessor in the HoTT receiver can process both undistorted signals from its transmitter as well as distorted control signals. Only when the sig­nals are excessively distorted or garbled, for example from noise, the processor replaces them with control signals that are saved in the receiver depending on the settings described below (hold or fail safe mode). This allows intermittent disturbances such as drops in field strength, etc. to be overlooked which would otherwise lead to familiar "wobbles".
Fail Safe
What to do in case of a malfunction
Therefore the "Switch-on fail safe" function ensures that as far, after switching the receiver system on, no valid signal from the transmitter is received, all the servo outputs are provided with pre-definable signals so that e.g. a retractable landing gear will not close unexpectedly or other unwanted things happen.
Function description
The "Fail Safe" function determines the response of the receiver both by directly switching on the receiver system and when there is an interruption in transmis­sion from the transmitter to receiver.
The servos connected to the receiver outputs 1 to max. 12 can then ...
• ... after the receiver is powered on and until there is no signal from the transmitter, take the positions saved in the receiver. Completely independently from receiver settings "hold" or "pos".
Notice
The standard setting, until a change occurs, is the central position.
• ... in case of interference ...
1. ... maintain the current position ("hold").
In case of transmission interruptions, all servos programmed to "hold" remain at their position which was last identified to be correct until a new, correct control signal is received by the receiver.
2. ... after the preselected "failsafe delay" move to
a selectable position ("pos").

Finally, in the bottom line "Delay", repeatedly touch the value field to choose the desired delay from among the four delays (0.25 s, 0.5 s, 0.75 s and 1 s), for example:
Notice
After having set the fail-safe positions so as the proper delays, the settings saved on the trans­mitter must be transmitted to the receiver. Other-
wise the settings could not be used in case of fail safe.
Switch at least now the receiver on and transmit the selected F/S values to the receiver by tapping on the
STO button, so that the setting can be recall in case
they will be needed.
Touch
The successful storage of the data is shortly con­firmed in the display an at the same time the F/S value fields will be unmarked again.
Otherwise check the correct radio transmission be­tween your transmitter and receiver systems and re­peat the process.
Tip
By tapping on the needed F/S button in the "MODE" column the stored fail safe position can be recalled and changed as described. Unchanged F/S values will be unmarked as soon as the sub-menu has been left.
WARNING
• The fail safe settings stored in the transmitter will not be automatically transmitted to the receiver during the operation! Their transmission must be manually performed within a radio connection by tapping on the STO but­ton!
• The fail safe settings stored in the transmitter should be restored after changing a receiver and should be de­leted in the previous receiver by Re-
set.
• Use this safety option to program a Fail Safe for at least the motor throt­tle position in gas models while idling, or to program the motor function to stop with electric models, or to hold with helicopter models. This makes it more difficult for the model to operate independently after switching on the receiver system or in case of malfunc­tions and cause property damage and injury. If necessary, ask for assistance from an experienced pilot.

The display switches to the "green" base menu. Touch the menu item "Trim Step".
Touch
The two control sticks come with digital trimming. With each click, briefly touching the trimming control moves the initial position of the control stick by a cer­tain value. If it is held, the trimming moves in the cor­responding direction with increasing speed.
The current trimming positions are displayed in the main display, and adjustments are audible. It is there­fore easy to find the middle position during model use without looking at the display: When you pass over the middle position, a brief pause is inserted.
The current trimming values are automatically saved when the model memory is switched.
For factory setting the mz-24 HoTT Pro transmitter original trim is saved in relation to the model memory but you can change this setting by assigning to each flight phase a different trim setting.
Phase depending settings
The here mentioned sub-menu offers the possibility to store phase specific values. Recognizable on the top left side of the display in green color is displayed the phase name. As standard is displayed the name of the phase 1, which is indicated by the name "NORMAL" or "PHASE 1". As soon as you will have defined one or many other phases in the "PHASE" menu, you will be able to switch among thosse phases. Activate the corresponding switch or switches if desired to switch between the phases.
CO / SE option buttons (global/phase)
The setting of CO (global) or SE (phase) is performed in the top left side of the display, where the trim of the throttle/brake or throttle/pitch control stick, generally also called control function CH1 (channel 1), is set as "global", which means phase dependent.
Touch this button at the top left of the display …

... sets the trim of the control function 2 ... 4 from phase influencing (CO (global)) to phase specific (SE (phase)) and vice versa.
"STEP" line (trimming step) With each click, the four digital trimming controls shift
the neutral positionof the respective control stick by an increment adjustable between "01" and a max. of "10" in each direction. The maximum trimming pathis always approximately ±30 % of the control path in­dependent of the selected number of trimming steps.
Notice
This setting is always "global" independent of the setting CO (global) or SE(phase).
To change the current step of a trim control, touch the corresponding value field in the "STEP" line, for example:

Tip
The numbering of the trim controls T1 … T4refers ex­clusively to the assignment of control channels 1 … 4. Whether aspecific name relates to a trim control of the left and right control stickdepends on the control mode selected in the "ST mode" sub-menu of the system menu.

"POS" column. (The trimming range is about ±30 % of the entire control path.) They can appear as follows for example:
"SET" line (saving trimming positions) This option allows you to optionally save the current
position of the four digital trimmings so that they can be returned to the visual middle position. After a mod­el memory is changed or after long periods between flights, the last safe trimming positions are available in the middle positions of the respective trimming dis­play of the control functions 1 … 4.
Say for example you have landed your model and trimmed it. The current trimming positions are displayed white in the "POS" line approximately in the middle of the display. (The trimming range is approx­imately ±30 % of the overall control path.) The value fields in the "SET" line underneath display the saved trimming and, since no values have yet been saved, the value fields all contain 000%. The display there­fore appears e.g. as above in the section "POS" line.

AUTO TRIM
The "AUTO TRIM" function offers you the possibility to trim a model easily and quickly, for example during the first flight or after (bigger) reparations or similar.
During such kind of "first flights" the previous set­tings of the model performed on the ground may not fit 100% with the flight requirements, in those cases you usually need to move the control sticks in order to correct the model attitude until it flies straight and at the same time you have to move the trim controls to obtain the same effect.
Exactly here is the "AUTO TRIM" function useful: after having reached the required flight attitude through the control functions 2 ... 4 this function is activated mov­ing ONCE an intermittent switch previously assigned, normally a self neutralizing switch. For example the 3-position switch S8, which push function after the assignation is declared as ON position. (For safety reasons - see what follows in the "Notice" - is strictly recommended not to use a switch with a permanent "ON" position):
As consequence of pushing the switch, the deviation of the control sticks positions 2 ... 4 from the related neutral positions are stored as trim value, within max­imum ±30 %, in about 1 second. At the same time the control sticks can be released to the normal position, for example:
Notices
• For safety reasons never use the "AUTO TRIM" option if you have set "0" as trim step.
• Be sure that the control sticks 2 ... 4 are in their neutral position while the switch is as­signed. Otherwise the deviations from the neutral position will already be stored in the trim memory as trim values.
• EACH activation of the AUTO TRIM switch acts cumulatively, that is why for safety rea­sons is strictly recommended to use the switch only once and to deactivate it after the "AUTO TRIM flight" has finished. Otherwise there is the risk that the "AUTO TRIM" function might be inadvertently activated.
• Never assign a "normal" position holding switch to the "AUTO TRIM" function or always affordable bring the switch to the "OFF" posi­tion after each AUTO TRIM process. OTHER­WISE EVERY ACTIVATION OF EVERY OTHER SWITCH WILL INHIBIT THE FUNCTION OF THE AUTO TRIM PROCESS.
• The storage of the trim values from the "POS" line in the "SET" line so as the reset of the values is performed as described at the begin­ning of this paragraph.

Near the gimbal sticks for the control functions 1 ... 4 and their trim controls the mz-24 HoTT Pro trans­mitter is provided as standard with other control ele­ments:
• 1 two-position switch with long handle (S6)
• 1 three-position switch with long handle (S3)
• 4 three-position switches with a short handle (S1, S4, S5 and S7)
• 2 one-side, self-neutralizing three-position switch­es with long handle (S2 and S8)
• 2 INC/DEC buttons (DT1 and DT2)
• 2 rear proportional sliders (SL1 and SL2)
• 4 proportional dials (DV1 … DV4)
In contrast to the two control sticks that immediately act on the servos connected to receiver outputs 1 ... 4 with a newly initialized model memory and for an heli­copter model also for the servo 6, the aforementioned control elements are initially inactive.
Consequently, only the servos controlled by the two control sticks can be moved when these systems are initially delivered and a new model memory is initial­ized and bound to the receiver to be installed. In con­trast, the servos connected to different slots remain in their middle position.
Even though this may initially appear to be inconve­nient ..., it is the only way to freely select from the "other" control elements of your transmitter and avoid the deactivation of unnecessary control elements. A not needed control element, erroneously actioned, also has then no influence on your model if it is not ac­tive, it means when it is not assigned to any function.
As needed, you can therefore assign all of the afore­mentioned control elements within the "CTL Set" sub-menu addressed here to any function input with­out restriction, . This also means that each of these control elements can also be simultaneously assigned several functions as needed. For example, the same toggle switch that is assigned to an input in this menu can also be assigned as a timer on/off switch in the "Timer" menu, etc.
Notices
• It should be noted that incorrect responses may arise from functional overlaps such as using the same physical switch as a switch to switch between Phase switch and as a control for Phase trimming. Change also your switch assignment.
• In contrast to setting servotravel, setting the control travel affects all outgoing mixing and coupling functions and hence all servos that are activated by the relevant control element.

After the initialization of a new model memory with the model type "helicopter" in the transmitter mz-24 HoTT Pro the input "12" is provided with the "throttle limit" function. This function is standardly deactivat­ed and remains so until NO control is assigned to the input 12:
Notice
The throttle limit is deactivated until the input "12" is free! This input cannot be used for any other use!
By assigning a control, for example the momentary proportional dial DV2 on the top left side of the trans­mitter, the following described "throttle limit" function will be activated again and it can be set according to the following description.
Throttle limit function
With this setting and the assignation of a control to the input 12, it is unnecessary to program two phases (THR.HOLD and no THR.HOLD) that is frequently the usual approach with other remote control systems.
As opposed to THR.HOLD, increasing the system speed below hovering is much more flexible and can be adjusted more precisely with the options offered by the they mz-24 HoTT Pro transmitter.
Meaning and use of throttle limit
In contrast to fixed-wing models, the performance of the power unit for helicopters cannot be directly controlled with the CH1 control stick; it can only be indirectly controlled by the gas curve settings made in certain helicopter menus of the function menu, or by a governor if the model has one.
Tip
For different phases,you can of course also adjust indi­vidual gas curveswhen programming the phases.
Both methods of controlling the output prevent carbu­retor motors of a helicopter from approaching idling during normal flight which allows them to be reliably started and stopped without additional intervention.
The gas limit function elegantly solves this problem by limiting the position of the throttle servo or the per­formance of a motor control unit: This makes it pos­sible to optionally turn down the throttle to idle with the throttle limit control, upon which the trim control of the throttle/pitch control stick assumes control, or to directly turn off an electric drive. Conversely, the throttle servo or motor control unit can only reach its full throttle position when the throttle limit control also releases the entire travel.
The set value on the (right) plus side of the "Travel" column of the function menu, therefore has to be large enough so that, when the throttle limit control is at its maximum position, the full throttle setting achievable by the throttle curve settingsis not limited. Normally, a value between +100 % and +125 % is set.
The value on the (left) minus side of the "Travel" col­umn should be set to allow an electric drive to be reliably turned off with the throttle limit control, or to allow a carburetor to be closed enough so that the ICE engine can also be turned off in conjunction with digital CH1 trimming. This value should therefore be left at +100%.
This variable limitation of the throttle travel allows the drive to be comfortably started and stopped, and generally this approach is significantly safer. Imagine what could happen if for example you carried a heli­copter to the takeoff site while the motor is running and accidentally activated the CH1 control stick.
If the carburetor or motor control unit is open to much, a beep sounds when you turn on the transmitter or after a model change, and the following message ap­pears in the main display:
94 Base menu - Control/switch setting | Throttle limit function
Page 95
At the same time as long as the automatic switch on of the RF module is inhibited, until the throttle limit or the throttle/pitch control stick let the output signal of the channel 6 be out of the idle range.
Tip
View the "Servo monitor" to monitor the influence of the throttle limit control. Be sure to remember that servo output 6 controls the throttle servo in the mz-24 HoTT Pro transmitter.
Idle basic settings
Open the throttle limit until the end point. Move the throttle/pitch control stick to the maximum pitch posi­tion and, in the sub-menu...
»Throttle curve«
... of the function menu, make sure that the standard gas curve is active.
If the standard gas curve has already been changed after a model memory has been initialized, reset it (at least temporarily) to "POINT L = 0%", "POINT 3 = +50%" and "POINT H = +100%":
Notice
Since the throttle trimming lever does not work when the throttle limiter is open, its position is ir­relevant in this case.
Without starting the gas engine, adjust the throttle servo (preferably mechanically), and if desired addi­tionally by adjusting the travel of servo 6 in the sub­menu "E.P.A." of the base menu to completely open the carburetor.
Then completely close the throttle limiter, for exam­ple by turning the proportional dial "DV 2" all the way clockwise. Use the trimming control of the throttle/ pitch control stick to move the marking of the trim­ming position into the motor OFF position.
Notice
The position of the throttle/pitch control stick is irrelevantwhen the gas limiter is closed. It can
therefore remain in the maximum pitch posi­tion as long as you can switch between full throttle (throttle limiter open) and "Motor OFF" (throttle limit­erclosed) using just the throttle limiter when adjusting the carburetor linkage.
While the gas limiter is closed, adjust the carburetor linkage so that the carburetor is completely closed. Make sure that the throttle servo does not mechan­ically over-travel in the two extreme positions (full throttle/motor OFF).
To conclude this basic setting, match the setting range of idle trimming with point "L" of the gas curve. Adjust point "L" of the "throttle curve" display to ap­proximately +15 to +18%, for example:
To precisely adjust a seamless transition from idle trimming to the throttle curve, move the pitch control stick back and forth slightly at the minimum stop while the throttle limiter is closed and idle trimming is com­pletely open. The throttle servo should not move. Any subsequent adaptation of the gas curve must be done later during flight.
The motor should always be started with the throttle limiter completely closed. Adjusted the idle only with the trimming control of the throttle/pitch control stick, and turn off the motor with digital trimming.

The throttle servo is as­signedto transmitter output "6", and the pitch servo is assigned to output "1". You may wish to keep the pre­vious configuration. In this case, switch channels 1 and 6 so that (as described above) (control) channel 6 is at output 1 and vice versa.
Notice
By using the receiver-side channel assignment functioncalled "Channel Mapping" which is inte-
grated in the "Telemetry" menu of the mz-24 HoTT Pro transmitter,the 12 control channelsof these transmitters can be distributed as desired within one re­ceiver as well as to several receivers.

In addition, several receiver outputs can be assigned the same control function. For the sake of clarity, it is strongly recommended to only use one of the two op­tions.

Telemetry
Settings and displays
Receiver settings and the displays and settings of the connected telemetry sensors can be retrieved and programmed in real time in the "Telemetry" menu. The connection to the receiver is maintained by the feedback channel integrated in the HoTT receivers.
Up to four sensors can be connected through a V or Y cable at the telemetry connection of the HoTT receiv­ers provided with actual firmware.
The ability of these and future receivers to be updated by the user keeps the associated "Telemetry" menus current and allows additional functions or languages to be added.

Notes
• These instructions are based on the functions available at the time at which this manual was drafted.
• As already noted in the section "Binding sev-
eral receivers" on page , if desired several re-
ceivers per model can be bound. In the related programs of the mz-24 HoTT transmitter, you can directly manage one or two receivers and use a menu to distribute the 12 transmitter control channels between the two receivers.
During subsequent operation, only the receiv­er selected in the line "RECEIVER SELECT" of the "Telemetry" menu can establish a telem- etry connection with the transmitter. As stan­dard it is the last bound one.
Conversely, this also means that only these receivers can be addressed by the "Teleme- try" menu. The selection therefore may have to change before settings can be made to a specific receiver, because the second and all the other receivers work in parallel in the so called "slave mode"!
• The exchange of telemetry data between transmitter and receiver takes normally place only after each four RC data-packs or even after even bigger distance, see next page. Therefore also the reaction to control buttons or setting changes has normally within a te­lemetry connection a delay. This does not constitute an error.
• When adjusting the remote control, make sure that the transmitter antenna is always far enough from the receiver antennas. Maintain a distance of 1 meter to be on the safe side. Otherwise, you risk endangering the connec­tion with the feedback channel and causing malfunctions.
• All settings that have been made using the "Telemetry" menu (such as fail safe, reversal of the direction of servo rotation, servo travel, mixer and curve settings, etc.) are only saved in the receiver and are therefore transferred to other models when the receiver is switched.
You therefore need to reinitialize your HoTT receiver if you want to use your receiver in an­other model (see "Reset" on page Reset).
You should therefore only program the rota­tional direction of servos, servo travel, mixer and curve settings, etc. in a model specified standard menu of the respective transmitter. Otherwise, the settings will overlap each other which at least will cause a lack of clarity and, at worst, will cause problems in subsequent operation.
• By using the receiver-side channel assign­ment function called "Channel Mapping" which is integrated in the "Telemetry" menuof the mz-24 HoTT Pro transmitter,the control channelsof these transmitters can be distrib­uted as desired within one receiver as well as to several receivers. In addition, several receiver outputs can be assigned the same control function. For example, this is useful if you wish to actuate each aileron with two servos instead of just one, etc. Also here it is strictly recommended to pay maximum atten­tion during programming.
WARNING
• When operating towed models, main-
tain a minimum distance of approxi­mately 50 cm between the participat­ing receivers or their antennas. Using the satellite receiver is an option. Oth­erwise, malfunctions from the feed­back channel are possible.

• The model or sensors may only be programmed when the model is on the ground. Only perform settings when the motor is turned off or the drive battery is disconnected. Otherwise, unanticipated reactions may occur.
A servo test that is accidentally ac­tivated in the receiver, for example, could cause the model to crash and cause injury or property damage.
• In addition, consult the safety instruc­tions contained in the Part 1 of the manual included in the transmitter package.
Telemetry The menus that fall under the generic term of "Telem-
etry" can be accessed from the "free" function menu
of the mz-24 HoTT transmitter. You can open this function menu by touching the gear icon labeled "B":
Touch

Tap on the "Telemetry" icon to open the first page of the telemetry display:
Basic operation
Basically the "Telemetry" menu corresponds to the other menus of the mz-24 HoTT Pro transmitter: The few deviations are described below:
If you have bound a receiver as RX1 or also as RX2 in the sub-menu "TX ctl", then you can declare one of the two receivers as "Telemetry-receiver" by tapping on the standardly RX1 labeled value field. As stan­dard it is the last bound one. To change the standard setting ALWAYS on the right according to your pref- erence, tap on the value field. The color of the value field changes from black to blue:
Set the desired value with the + or – button at the right edge.
Value Explanation
ALWAYS The transmitter reacts standardly
to the back-channel of the selected receiver.
4x / 8x The transmitter reacts to the
back-channel of the selected receiver with the related delay.
OFF The transmitter telemetry functions
are switched off.
Notice
Actually the use of settings different from the standard value  ALWAYS is only suggested if
two receiver, which are not connected to each other and which are bound to two different transmitters, are intended to use in close distance and therefore there are oft disturbs in the back-channel of one of both re­ceivers.

Specifically if there is the possibility of reciprocal interfe­rence of the back-channels, as for example in a camera drone with separate camera and copter control or a to­wing model for model-parachute.
Touch the RES button to reset a changed value in the blue (and hence active) field to the default value.
Switch between the individual pages of the "Telem- etry" menu by touching the ENT button (forward) and ESC (reverse or) with a finger at a provided sty­lus. Corresponding pointers indicating direction can be found on each page of the display at the top right in the form of angled brackets "
" or " ", such as:
If there is only one angled bracket, you are on the first or last page. You can then only change pages in the displayed direction.
Menu lines in which parameters can be changed are indicated by a preceding angle bracket (see screen­shot above). Touch the INC or DEC button to move the "
" pointer one line up or down. Lines which can-
not be jumped cannot be changed. To change a parameter, touch the SET button at the
right edge of the screen. The selected parameter is represented in white.
Then use the INC or DEC buttons to change the selected value within the possible range; the changed value is confirmed and stored in the receiver memory by touching one more time the SET button.
Touch the ESC button at the top right of the display to return to the previous page and touch the BACK  button at the top left of the display to return to the initial position:
Notices
• If however the following message appears instead of the desired sub-menu, then there is no connection with the receiver. Switch on your receiver system or bind the correspond­ing receiver or activate it in the "RX SELECT" line as described before.
• If, however, you have opened one of the sub­menus described below and this is unex­pectedly replaced by, as the selection menu shown below, then the connection to your receiving system is lost. Then switch on the receiver system again or solve find the origin of the connection failure.
Touch the button of the desired sub-menu.
