1.2.2.5 Timer The specialised timers were replaced by universal timers.
Three operating modes are available for each timer: frame, sum, and
interval
The counting mode can be selected: Up or Count down You can select to have the time announced within 5 minutes before an
alarm occurs or the zero point is passed.
The timers can be renamed as desired.

1.5 Basic safety instructions
The following basic safety instructions and warnings are an essential
component of these operating instructions and are fundamentally
important for device handling.
Read the instructions carefully!
Make sure that you have carefully read these operating instructions and the following safety instructions before setting up the device for operation.
Radio-controlled models are not toys in the usual sense. Assembly, installation, and operation of the RC system require technical knowledge, care, safety-awareness and responsibility. Errors or negligence can lead to considerable damage. Since the manufacturer or the seller does not have any influence and control over the proper setting up and operation of a model, such risks are expressly pointed out here and any liability whatsoever is excluded.
A model that goes out of control for whatever reasons can cause significant damage to property or personal injury. Be aware of safety at all times. Make sure to take out general liability insurance.
Do not modify the radio control system. Use only original accessories and spare parts.
If the device is operated in combination with third-party products, ascertain their quality and functional reliability. Each new or changed combination must undergo careful functional testing, including a range check. Do not operate the device or model if there appear to be any problems. First identify the error and troubleshoot it.
In particular, have the radio control transmitter and the receiver inspected at an authorised MULTIPLEX Service Centre (see section 10.1 "Specifications" on page 212) at regular intervals (every 2 to 3 years).
Operate the transmitter only in the permissible temperature range (see section 10.1 "Specifications" on page 212). Bear in mind that condensation may form in the transmitter due to sudden temperature changes (e.g. warm car, cold environment).
Page 17
Introduction
Page 14
PROFI TX
Moisture may impair the function of the transmitter and other components of the radio control system.
If moisture accumulates in electrical devices, immediately stop using the device, disconnect it from the power supply and allow it to dry in the open state as far as possible (up to a few days). Thereafter, perform a careful functional test. In case of major condensation, have the device inspected at an authorised MULTIPLEX Service Centre (see section "1.2" on page 9).
Operation of the radio control system is allowed without restrictions within EU territory and Switzerland.
Program a new model at home in peace. Make sure that the power system of the model cannot start up unexpectedly. Check all functions carefully. Completely familiarize yourself with the operation of the transmitter before putting the model in operation.

1.6 Safety instructions for the transmitter battery
The transmitter battery powers the device and plays an important role in operational safety. The charging circuit integrated in the transmitter matches the battery. Do not charge the battery outside the device.
Batteries are not toys: They must be stored out of the reach of children. Damaged or defective batteries must not be used and should be disposed of
properly (see section 1.12 "Disposal" on page 22).
Do not heat, incinerate, open or short-circuit rechargeable batteries, do not charge or discharge them at excessive currents, do not overcharge them, avoid deep discharge, and do not charge with reversed polarity. Observe of the permissible temperature range for the battery.
Mishandling the battery incurs the risk of combustion, explosion, chemical burns and fire.

1.7 ESD notes for electronic sub-assemblies
The sub-assemblies of radio control transmitters (main circuit board, modules) are fitted with electrostatically sensitive components. These parts can be destroyed, suffer imperceptible damage or have their useful life shortened if static discharges take place (potential equalisation through electro-static discharge) when the sub­assembly is touched.
The following protective measures are essential if you have to handle electrostatically sensitive sub-assemblies:
Before fitting or removing such sub-assemblies, equalise the electrical
potential difference between yourself and your environment (e.g. by touching a heating radiator).
Open the basic device and touch it over a large area in order to equalise
the potential relative to the base unit.
Do not remove any sub-assemblies from their conductive anti-static bags
until you have equalised the potential. Avoid touching electronic components or solder pads directly. Hold the sub-assembly by the edges of the circuit board only.
Once removed from the basic device, the sub-assembly should only be
stored in the conductive anti-static bag in which it was delivered. Never allow the sub-assembly to make direct contact with a conventional, non-ESD compatible container made of foam, Styrofoam or other plastic.

move smoothly and freely, and are not stalled even at maximum travel. Do not use the radio control to regularly limit servo travels. Preferable: Adjust control surface levers and pushrods mechanically and as thoroughly as possible. Avoid lost motion (sloppy linkages). Use configuration options on the servo side of the RC transmitter only for fine-tuning.
Observe the above-mentioned guidelines to make full use of the resolution (positioning accuracy) of your radio control system.
Provide effective protection from vibration to the receiver, battery, servos
and other RC and electronic components. Observe the advice included in the relevant operating instructions. Balance propellers and rotor blades before use and replace them at any sign of damage. Install I.C. engines on vibration-absorbing mounts and replace motors or motor parts which are damaged or do not run true.
Do not strain or bend cables; protect them against rotating parts. Keep servo cables as short as possible. Use cables with sufficient cross-section. Do not coil up or shorten the receiver aerial. Do not lay the aerial on or close
to electrically conductive components. Deploy aerials outside of fuselages with a shielding effect (carbon fibre, metallic painted finish).
Ensure that the receiver power supply is of adequate capacity. For servos up
to about 40Ncm torque you can estimate the required battery capacity using the following formula: Capacity [mAh] ≥ number of servos x 200 mAh. Use the next larger size of battery!
Take care to maintain sufficient distance between cables carrying heavy
currents (e.g. electric power system) and the RC system. Especially the cables between brushless electric motors and their actuators must be kept as short as possible (guide value: max. 10 to 15 cm).

Check the model regularly
Free movement and zero backlash of control surfaces and linkages. Stability and flawless condition of pushrods, linkages, hinge joints, etc. Carry out a visual check for fractures, cracks, possible shear points etc. on
the model itself, and in its components such as the RC and power systems.
Flawless condition and contact stability of cables and plug connections. Absolutely essential: Examine the power supply and its wiring, including the
switch harness, and the external condition of the battery.
This entails regular maintenance of the batteries and periodic checks of the voltage curve and capacity, employing a charge process and battery charger suitable for the type of battery in use.
Pre-flight checks
Charge the transmitter, receiver and power system batteries carefully to full
capacity, and verify their state of charge at regular intervals.
Ensure that the correct model memory is active on the transmitter. Carry out a range check (see section 2.6 "Range check" on page 46). Check the function and effect of all primary and secondary control systems.
If you discover any irregularities, do not fly. Locate the problem, eliminate it, and then check again.
When operating the model:
If you have never flown a radio-controlled model before, it is highly
recommended you consult an experienced model pilot when getting started. A trainer (buddy-box) system is ideal for taking the first steps in learning to fly.
Models should only be operated at suitable sites. Never fly or drive over or towards spectators. Do not carry out any high-risk flying or driving manoeuvres. Know your limits: do not over-estimate your abilities and skills. If you detect any sign of a problem or interference, land or cease operations
immediately.

2.4 Transmitter battery
The PROFI TX is powered by a robust and durable LiFePO4 battery. The battery is installed with the electronic system for battery management in a welded case. If the battery is new, the battery capacity of 4000mAh provides an operating time of more than 30 hours. Additionally installed components increase power consumption and shorten the operating time. If the device is exposed to temperatures below -10°C, the operating time is significantly reduced.
2.4.1 Charging the battery
The PROFI TX features two USB sockets at the front on the right-hand side of the case, which are protected by a sliding latch. The mini USB socket is used for charging (see section 2.1.5 "Connectors" on page 29).
The following options are available for charging the PROFI TX:
Via your PC or laptop Via the MULTIPLEX USB car plug-in charger 12V DC
(item no. 145533)
Via the MULTIPLEX USB plug-in charger 100-240V AC
(item no. 145534, see section 10.2, "Accessories" on page 213)
The transmitter must not be connected to a charger when no battery is in­stalled!
Without a consumer, the charger can provide unacceptably high output voltages. These voltages can damage the transmitter.

2.4.4 Battery management
The PROFI TX records the current during transmitter operation and while charging the transmitter battery. The available battery charge is calculated on the basis of the power meter reading, the temperature and the voltage. The remaining operating time (time to empty) is calculated from charge and current and is shown on status display #2 (see page 88). The calculation takes into account that current consumption slightly decreases with decreasing battery voltage.
Battery alarm
If the remaining operating time falls below a configurable threshold, the remaining operating time is announced with increasing frequency. The "TX-BATT." section on the left side of status display #2 flashes.
The factory setting for the alarm threshold is 60 minutes. This value can be changed in the Setup > Transmitter > Battery alarm menu (see section 4.3.9 "Transmitter" on page 114).
Self-discharge
If the transmitter is stored for a prolonged period, the available battery charge is estimated based on the idle voltage when the transmitter is switched on. For this reason, the displayed charge and time to empty are not initially very accurate. After one to two charge / discharge cycles the original accuracy is restored.
Under-voltage cut-off
If the operating voltage falls below 2.8V, the device is automatically switched off without further warning. If the voltage is below 2.9V, it cannot be switched on: The following message is briefly displayed on the screen: BATTERY DOWN!
Charge the transmitter battery!
If voltage is low, recharge the battery as soon as possible (within 1-2 days) to avoid damage due to deep discharge. Observe the notes on charging (see section 2.4 "
Transmitter battery" on page 40).

2.6 Range check
Regular range checks are necessary for ensuring the reliable functioning of the radio control system and for timely detection of changes in transmission properties. Always perform a range check after:
installing, modifying or rearranging components in the model, reusing components in the model that were involved in a crash, observing irregularities when operating the model.
The transmitting power can be significantly reduced for the range check, enabling short distances between transmitter and model.
While the range check is active the status displays #2 to #8 show the flashing message: RANGE! with the annular ring flashing red. A warning is announced every minute to alert the operator. The warning is only announced when your are not navigating in menus so as not to disturb you when performing configurations.
Recommended minimum distance: 40m to 100m, depending on receiver type. Refer to the receiver operating instructions for detailed information.
Always perform a range check before starting up the model. A second person must always be present for the range check to secure and
observe the model. Large metal objects within or in close proximity to the checking range (wire fences,
cars) affect the result of the range check.

Page 47
Procedure
1. If the model is fitted with a power system, switch it off!
2. Press and hold the §button on the transmitter as you switch the transmitter
on.
3. Switch on the receiver.
4. In the Servo > Test run menu, activate the test run for a control function,
e.g. Elevator. This allows you to check that the receive system responds to control commands with distinct, regular movements of the control surfaces.
5. Increase the distance between transmitter and model. You have reached the
range limit when the servos start to jitter.
6. Repeat the check with the power system running. Secure the model. Perform
the check using throttle positions that vary between idle and full throttle. In case of electric power systems, the most significant interferences occur at half throttle.
The range should not diminish significantly.
7. Otherwise, eliminate the cause of the interference (power system, installed
position of the receive system with power supply).
Factors influencing the radio range
The following factors have significant influence on the radio range:
Environmental conditions
Hilltops, ground characteristics, type of terrain, and the atmospheric conditions affect radio range.
Receiver technology and sophistication
Technically sophisticated receivers have a greater range than simple, cheap receivers.
Installation situation in the model
Installation position / arrangement of the aerials and the distance to batteries, power systems, servos, ignition systems, metal / carbon fibre parts influence the radio range.
Binding
The binding procedure binds the receiver with the transmitter. M-LINK uses "frequency hopping" and "spread spectrum". No fixed transmission channel is used for "frequency hopping", but all 39 channels
are used in a sequence that is defined by the transmitter.
Page 51
Transmitter
Page 48
PROFI TX
For "spread spectrum", every data bit is coded in 64 bits (spread). This procedure provides a high level of immunity to interference. During binding, the transmitter passes "hopping sequence“, "spreading code", and "response time" to the receiver.
Procedure
The binding procedure can be started in 2 ways: via the keypad during startup or via the menu.
Starting the binding procedure when the device is switched on:
1. Press and hold the ¡ button for the full duration of the transmitter startup
procedure. o The annular ring of the Power button is flashing in orange and the flashing
message "BINDING" is shown in the status displays #2 to #8.
2. Now, switch on the receiver while pressing and holding the Set button (connect
the power supply).
o The receiver LED is flashing rapidly.
3. The binding procedure is completed within a few seconds:
o The annular light returns to flashing yellow. o The receiver LED is flashing slowly. o The servos that are connected to the receiver can now be controlled.
Starting the binding procedure via the menu
1. Switch off the receiver and switch on the transmitter.
o Press the ¡ button to open the "Setup" menu. o Use the wheel to select the "M-LINK" menu item. Press the wheel. o Open the "Binding" menu item. Press the wheel . The input field OFF is
now highlighted.
o Turn the wheel to the right: The text "seeking.." is now displayed in the
input field and the annular light of the Power button is flashing in orange. The transmitter is searching for a receiver in binding mode.
o You can cancel the binding procedure at any time: Turn the wheel to the
left. The previous condition is restored.
2. Now, switch on the receiver while pressing and holding the Set button (connect
the power supply).
o The receiver LED is flashing rapidly.
3. The binding procedure is completed within a few seconds:
Page 52
Transmitter
PROFI TX
Page 49
o The input field briefly shows the text "OFF" and then indicates the
detected type: "RX", "RX-ID", "MultiFlight", "Teacher" or "Student".
o The annular light returns to flashing yellow. o The receiver LED is flashing slowly. o The servos that are connected to the receiver can now be controlled.
If the binding procedure does not complete automatically within a few seconds, move the transmitter front closer to the receiver aerial(s).
The Setup > M-LINK > Binding menu item indicates if and what type of receiver is currently connected to the PROFI TX.
The ID is displayed for ID receivers.
2.7 Trainer mode
The trainer mode (teacher / student) is the safest method for beginners to get started in model sport.
An experienced model pilot has control over the model as the teacher. The trainer can transfer control functions to the student by operating a button. Initially these will be individual control functions, and later all the main control functions will be transferred.
The PROFI TX can be configured either as a teacher transmitter or as a student transmitter. The teacher and student transmitters are inter-connected using a second M-LINK radio link.
If the radio link between the student and the teacher is lost, all the control functions are returned to the teacher.
Student mode
In Student mode, the control signals of the sticks and sliders are transferred via M­LINK to the teacher transmitter (without trim and travel settings).
A second PROFI TX with COPILOT module or another MULTIPLEX transmitter with trainer stick can be used as the teacher transmitter.
Page 53
Transmitter
Page 50
PROFI TX
Refer to "Training" on page 99 for details.
Teacher mode
A free switch on the teacher transmitter and the COPILOT module are required for the Teacher mode (see section 10.2 "Accessories" on page 213):
Refer to section 2.3.4 "Installing additional controls" on page 36 for
information on how to install a switch.
Refer to section 5.4.2 "Assign.Switches" on page 173 for information on how
to assign the switch to the trainer function.
Refer to section 2.3.5 "Installing additional modules" on page 39 for
information on how to install the COPILOT module.
In Teacher mode, the selected control functions can be controlled by the student transmitter. These control functions are selected in the Setup > Training menu. The selection list is only available in Teacher mode.
2.8 Digital trim
2.8.1 Overview
"Trimming" refers to the adjustment of the model aircraft to fly straight and level when you leave the sticks exactly at centre.
Digital trim has two essential advantages:
Digital trim buttons do not have any physical position corresponding to the
actual trim value (which is the case for conventional trim with trim sliders). The digital trim position is displayed on the screen, and any change to the trim values is stored in the model memory. If you switch model memories, there is no need to move the trim sliders to the correct position to suit the model. The correct trims are immediately available.
In models for which you have set up multiple flight phases each flight phase
has its own trim memory, i.e. it is simple to trim each flight phase accurately, and independently of the trims in the other phases.
Example
The model aircraft should fly straight and level when you leave the sticks exactly at centre. If this is not the case, the neutral point of the causal control function should be corrected / trimmed.
Page 54
Transmitter
PROFI TX
Page 51
Centre trim
The PROFI TX enables digital trim on each of the 4 stick axes. "Centre trim" is applied to the main control functions "Aileron", "Elevator", and
"Rudder". For "Throttle" you can choose between idle and centre trim. The centre trim only affects the control centre, but not the end-travels. Unlike standard trim, this offers the advantage that no control travel must be reserved for trimming: the servo travel is used fully.
Both servo end-points remain unchanged, regardless of the current trim position.
2.8.2 Trim buttons
On the PROFI TX, trimming is carried out using the trim buttons arranged below and to the side of each stick unit (see section 2.1.1 " Top view" on page 23).
Every time you press a button the associated control axis is trimmed in the direction in which the pressure is applied to the button. If you press and hold the trim button for more than about 0.8 sec., the trim value changes continuously until you release the button again (AUTO-REPEAT function). When the trim reaches the neutral position, the AUTO-REPEAT function stops briefly.
Each trim increment is accompanied by an audible signal. On reaching the neutral position or the end-point, specific audible signals are emitted.
As an option, the current trim value can be announced when the trim button is released. You can activate this announcement in the Setup > Transmitter >
Sounds menu (see section 4.3.9 "Transmitter" on page 114).
2.8.3 On-screen trim display
Graphic display
The trim positions are displayed as bars on both sides and at the bottom of the screen in the status displays #2 to #8:
Figure 7: On-screen trim display
Page 55
Transmitter
Page 52
PROFI TX
Starting from the centre position, the trim range is 20 increments in both directions. The trim increment (step, or adjustment rate) can be set to any of the following values: 0.5%, 1.5%, 2.5%, 3.5% (ControlFunctions > respective control function, Step size parameter, see section 4.4 "4.4ControlFunctions main menu" on page 118).
Switching the step size changes the trim value percentage since the number of stored trim increments remains the same. This means if you alter the trim increment size, you must remember to re-trim the model.
The design of the graphic trim display can be selected (Setup > Transmitter > Screen, Trim graph parameter, see section 4.3.9 "Transmitter" on page 114).

2.9 microSD card
2.9.1 Replacing the microSD card
Open the transmitter. Use a finger nail to carefully pull the metal card bracket (top part of the
socket) towards the transmitter centre to release the card bracket.
Flip up the card bracket and remove the card. Insert a new card into the card bracket (terminals facing to the back and
down).
Fold down the card bracket. Push the bracket with the card slightly back
until it snaps into place.
2.9.2 microSD card from a different transmitter
When inserting a card that was used in different transmitter, you must briefly remove the transmitter battery before switching on the transmitter. This erases the copy of the last model memory from the microcontroller RAM. Erasing the model memory prevents the transmitter from using the RAM copy further and accidentally overwriting the model memory with the same number on the new card when the transmitter is switched off.
2.9.3 New microSD card
Switch on the PC. Open the "Computer" or "My Computer" pane in the file
explorer.
Switch off the transmitter. Connect the transmitter to the PC via the
USB socket. After a few moments, you see an additional drive. That is the SD card in the PROFI TX.
o Right-click the new drive to open the context menu. o Select "Format". Make the following selection in the next menu:
file system: FAT; allocation unit size: 32 kilobytes; quick format
o Click "Start".
Rename the card to "PROFI TX":
o Right-click the new drive to open the context menu. o Select "Properties". o Enter the text "PROFI TX" in the input field.
Page 57
Transmitter
Page 54
PROFI TX
o Click "OK".
Now, copy the directory structure to the PROFI TX that is described below.
A zip file containing this directory structure is available in the Downloads section of our home page.
2.9.3.1 Directory structure on the microSD card The microSD card must contain the following 3 folders in the root directory:
AUDIO
Contains the 3 subdirectories DE, EN and FR. The subdirectories contain sound and speech output files for each language.
DATA
The model memories are stored in this folder. The file names are written in capitals and start with "PTX" followed by the model number (3-digit with leading zeros). The file name extension is .MDL.
UPDATE
Updates are placed in this folder. If the transmitter detects an update file during startup, the update procedure is started. The file is deleted upon successful completion of the update procedure.

Switch assignment
In the PROFI TX, all the switches can be installed and connected as needed. For this reason, switched functions that are usually assigned to dip-switches or buttons cannot be pre-set in the model templates. You have to configure these assignments yourself according to the existing switches.
Using timers
The Frame, Sum, and Interval timers are only functional if a switch has been assigned to them. The same control that is used for the Throttle control function is assigned to the sum timer in all model templates. For this reason, this timer is immediately functional. You activate the other timers by assigning a switch to them.
Control mixers (Ctrl.Mix)
The Ctrl.Mix control mixers are not initialised in the templates.

3.1.1 BASIC model template
This model template is designed for simple power or glider-type models and for models without aileron.
This model template should also be used for model flying simulators.
Servo assignment
If you install a second aileron servo to provide separate linkage for the ailerons, simply assign the Aileron function to a free servo (see "Assign" starting from page 149). Would you like to raise the ailerons as an airbrake? In that case, assign the AILERONS+ mixer to both aileron servos at the same position. The extended airbrake will cause major load distribution changes: Change the elevator to ELEVATOR+. It is then possible to compensate for the effects of Throttle and Spoiler (airbrake).

3.3 Templates for land- or water-based models and tracked vehicles
3.3.1 CAR / TRUCK model template
This model template is suitable for all types of vehicle models. The control functions Support Legs, Ramp, Light, and Aux-1 to Aux-4
provide the Slow function. This allows operating support legs and ramp at a realistically slow speed. Smooth transition for Light is also possible.
Flight phase switching originates from model flying, as the names suggests. This function has been left activated for vehicle models. Smart modellers will have good ideas for practical application.
Control function assignments and names can be changed as required. This template does not contain pre-defined mixers. To personalise control,
4 mixers on the control side and 7 mixers on the servo side are provided, each with eight inputs.

3.3.3 TRACKED V. model template
This model template is suitable for tracked vehicles. Control function assignments and names can be changed as required. Completed tracked vehicle models typically contain a functional building block that
combines "Throttle" and "Steering" for the two power systems. If you are using 2 separate speed controllers, it is recommended to change the
servo assignment for Steering and Throttle to TRACK+ (page 149). TRACK+ stands for a mixer that combines "Throttle" and "Steering". You configure
the required settings in the £ Mixer menu (page 132). Set a small deadband value in the mixer for Steering. If "Steering" and "Throttle" are assigned to the same stick unit, opening the throttle often involves a small steering movement. Applying a deadband to "Steering" solves this problem.
To personalise control, 4 mixers on the control side and 6 mixers on the servo side are provided, each with eight inputs.

4 The menus
The PROFI TX software is divided into status displays and menus that are structured in several levels.
4.1 Status displays
The 8 status displays provide information about transmitter, model and sensors. The status display is shown after transmitter startup or when exiting the main menus.
Press the + or – buttons or use the central wheel to toggle between screens. Every clockwise increment on the central wheel cycles to the next status display (see also section 5 "Operating the transmitter" on page 164).
Status display #2 is always active when the device is switched on or when a different memory is selected.
4.1.1 Status display #1
Turn the wheel to the left. Status display #1 provides an overview of the current battery and device status:
The device name is shown in the first line. The text can be edited (menu:
Setup > Transmitter > User data > Name parameter, see section
4.3.9 "Transmitter" on page 114).
The left half of the screen provides information about the battery, e.g. battery
voltage, remaining operating time (time to empty), etc.
The right half of the table provides information about the device, e.g. serial
number, total uptime count, etc.

These displays start to flash when the remaining operating time (time to empty) reaches the set alarm time (menu: Setup > Transmitter > Battery alarm parameter, see section 4.3.9 "Transmitter" on page 114). From then on, the remaining operating time (time to empty) is announced. Towards the end, the predicted operating time reduce quickly since additional power is consumed by the announcements. For this reason, we have included a small buffer.

If the sensor reports an alarm:
The sensor value starts to flash. The appropriate warning light for the sensor group below the screen
starts to flash (see section 2.1.1 " Top view" on page 23).
The device also starts to vibrate if the vibration alarm is activated
(see section 4.3.5.2 "Announce & Alert" on page 103).
If the sensor clears the alarm the value stops flashing. The vibration alarm and warning light remain active until they are cleared by pressing the
ENTER button. Notice: In other status displays the ENTER button has different
functions.

4.3.1 Volume
The general volume and the volume of the variometer tone are configured separately.
The figure below illustrates the default configuration of a newly created model memory. The following options are available:
Assign.Contr.: You can use any freely assignable control as volume
actuator. This also includes virtual switches (MagicSwitch and flight phases). The assigned control is used when the fixed value is set to OFF.
Fixed value: The setting range is OFF to 25.
The default setting is 16. When OFF is selected, volume control is transferred to the assigned control. If no control is assigned the device remains muted.
Special features:
General volume: When the volume is switched on using a control, the
announcement sequence of the sensor data is restarted.
Variometer tone: When the volume is switched on using a control, the
altitude is announced once.
PROFI TX 16 only: Servo 16 can be used as volume actuator. Complex
volume control scenarios can be implemented using mixers, e.g. the variometer tone can be muted when pushing/pulling and opening the throttle.

The menus
Page 96
PROFI TX
4.3.2 M-LINK
The radio link functions are set in the M-LINK menu.
Range check
When performing a range check, the transmitting power is significantly reduced to allow shorter distances between transmitter and model (see section 2.6 "Range check" on page 46).
Set Failsafe
The current servo positions are stored in the receiver. If Failsafe positions were stored in the receiver, the servos return to these
positions after 0.5 seconds.
o Use the respective PROFI TX controls to move the servos
(control surfaces) of your model to the desired positions.
o Set the value to ON. After a few moments, it reverts to OFF. o Check the Failsafe function by switching the transmitter off.
FastResponse
FastResponse reduces the transmission cycle from 21ms to 14ms. This reduces the response time for control commands. Only 12 servos can be controlled when FastResponse is active.
Not all servos work properly with FastResponse. Incompatible servos may vibrate excessively in idle position. Check your servo before starting off on the first flight.
FastResponse has a noticeable effect only on extremely agile models that are equipped with ultra-fast servos.

4.3.3 Flight phases
It is useful to have different settings and trims for specific flight phases when flying models. The flight phases technology in the PROFI TX provides an easy and convenient way to realize this. You can copy settings for one flight phase to another, disable flight phases if they are not needed, assign switches to flight phases, etc.
