the operating instructions and the safety instructions lead to expiring the warranty.
Graupner constantly work on the advancement of all remote control systems; changes of the scope of
delivery in form, technology and equipment we must reserve ourselves therefore. Please have under­standing for the fact that from data and illustrations of this operating instructions no requirements can
be derived.

Please keep these instructions for further reference!

1. INTRODUCTION

Many thanks for purchasing the Graupner M-G1 HoTT 2.4 module. This module is a direct replacement
for the standard RF module fi tted to your mc-19/mc-19s and mc-22s transmitters.

Please read right through these instructions before you attempt to install and use the system.

Installation requirements

We recommend that you have the module installed by a Graupner Service Centre. It is possible for the
modeller to carry out the conversion himself provided that he has a certain amount of manual skill, but
the transmitter’s fi rmware needs to be updated for the fi rst time in order to integrate the telemetry display
(mc-19s/iFS and mc-22s/iFS only), and this can only be carried out by the Graupner Service Centre Ger­many. Please note that we cannot offer a guarantee for all failures which have been caused by incorrect
installation, if you carry out the conversion work yourself.

2. PREPARING THE SYSTEM

First remove your previous RF module. For details of this procedure please refer to the appropriate
chapter in the operating instructions supplied with your radio control system. If you have previously
used a 35 MHz system, you will also need to replace the telescopic aerial with the Graupner HoTT aerial
supplied in the set. This requires the use of the aerial conversion kit for tray-mounted transmitters, Order
No. 23049 - see Figs. 1 to 5.
If you have previously used a 2.4 GHz system such as Graupner iFS, all you need to do is unplug the
existing aerial from the module.

1. Position the aerial lead and the blue four-pin module plug as shown in Fig. 6.

2. Fig. 7 shows the white rectangular socket for the module plug, and the circular aerial socket.

3. Press the four-pin module plug into the socket on the module using light pressure. The connector sys­ tem is polarised: note the lateral lugs. Ensure that it engages fully (arrows), so that there is no chance
of it working loose in operation (Fig. 8).

4. Position the module in the mounting frame. Locate the loops at the top (marked black), fi t the M3
screws (supplied - marked yellow) and tighten them fully to secure the module (Fig. 9). The 14-pin
plug of the optional interface cable No. 33304 (needed for internal telemetry, only available after
transmitter update) which terminates the interface lead should now be plugged into the socket on the
transmitter circuit board (Fig. 9 - 1). The connector system is polarised: note the lateral lugs. Ensure
that it engages fully, so that there is no chance of it working loose in operation. Finally connect the
plug marked “MODULE” to the USB 1 socket (Fig. 9 - 2); the brown wire must be at the top.

5. Connect the aerial plug to the aerial socket on the module circuit board (Fig. 10). It is best to use
tweezers for this: push the plug into place as straight as possible, to avoid damaging the contacts.

6. Secure the aerial lead by applying a drop of adhesive at the point marked in Fig. 11.

7. Now attach the back panel to the transmitter again.

8. Finally go to the transmitter „basic setup model“ menu and choose „modulation“ PPM 18 (for max. 9
servos) or PPM 24 (for max. 12 servos). Also when using the channel mapping with more than 9
channels choose PPM 24. JOB DONE!

5. GENERAL NOTE

MULTIC 1 / 2

Multichannel 1 or 2 (Nautic-Expert-Module Order
No. 4108)

When switching on or adjusting the radio control system it is essential to keep the transmitter aerial at
least 15 cm away from the receiver aerials at all times. If the transmitter aerial is too close to the receiver
aerials, the receiver will be overloaded, causing the red LED on the receiver to light up. The transmitter
responds by emitting a beep once every second; the red LED also goes out. The radio control system
is now in Fail-Safe mode.
If this should occur, simply increase the distance between the aerials until the audible warning signal
ceases, and the red LED on the transmitter lights up again; at the same time the red LED on the receiver
should go out.

Please note: if you wish to switch the transmitter on again just after switching it off, please wait at least
fi ve seconds to ensure that the transmitter has time to shut down completely. If you neglect to do this,
there will be no connection between transmitter and receiver: you will hear a beep repeated about once
per second, and at the same time the red LED on the transmitter will go out, and the LED on the receiver
will fl ash red.

5.1. Transmitter Display (TX-Display)

The telemetry can be programmed directly on all HoTT transmitters whose telemetry menu is integrated
directly into the transmitter’s screen (this is possible with most models after a fi rmware update). If this
update is not carried out, programming is only possible using the SMART-BOX.

The SMART-BOX, Order No. 33700, must be used for programming if you are using any of the
following transmitters: mx-22, Order No. 4801 / 4802, mc-19, Order No. 4821, mc-22, Order No. 4818

and mc-18, Order No. 4835. The Smart Box is used instead of the interface cable connected to the
USB1 socket.The following instructions describe the method using the SMART-BOX; the table below
shows variations which apply to the Telemetry menu for the various models of transmitter:

Transmitter low-voltage warning (ALARM VOLT): you can adjust the low voltage threshold at which
the alarm (continuous beeping) is triggered; the available range is 4 - 15 V.
When the alarm is triggered, “VOLT-E” fl ashes at top right in the SMART-BOX transmitter display, and
the parameters ACTION VOLT and ALARM VOLT are displayed in inverse form.

Please note: the transmitter’s own low-voltage warning (beep), as set in the “General settings”
menu, is triggered independently of the value set under TX-Display!

Binding a receiver (RX BIND):

refer to chapter 6.1. Binding

SD card function (SD SAVE): refer to chapter 6.8. Data storage

Country selection (COUNTRY): The Country setting is present in order to cater for various directives

(FCC, ETSI, IC etc.). The HoTT 2.4 radio system features a restricted frequency band for France. If
you wish to use the RC system in France, the country setting on the transmitter must be set to “France”
mode, as described. It is essential not to use the Universal/EUROPE mode. Factory setting is GENE­RAL. See also point 6.4.

Range checking (RANGE TEST):
switches the range test on or off, the remaining time is displayed. The display also works if the range
check is started with the BIND / RANGE button on the transmitter. See also point 6.2.

Multichannel 1 / 2 (MULTIC 1 / 2: Multi-channel function for the use with the Nautic-Expert-Module
order no. 4108. Up to 2 multi-channel channels can be used, the appropriate channels must be set in
the display under MultiC. If no Nautic module is used, set MULTIC to 00.

Parameters which have different options in the Settings column of the table can be adjusted using the
SMART-BOX. If there are no options, the screen simply displays the parameter data. If you wish to carry
out an adjustment, you must use the INC or DEC buttons above the screen to select the desired para­meter (e.g. ALARM VOLT) by moving the arrow cursor (INC moves the cursor down, DEC moves it up).
Simultaneously pressing the INC and DEC buttons switches the parameter to be adjusted to inverse
video (white on black); this indicates that it can be programmed: pressing the INC button at this point
increases the value, pressing the DEC button reduces the value. When the adjustment is complete,
save the selected setting by pressing the INC and DEC buttons simultaneously; the dark background
now disappears in order to confi rm this action.

at the top right corner of the transmitter display (TX).
There may be a slight delay in the screen’s response to inputs using the top
buttons, since all the settings are transmitted directly to the receiver by wire­less means.

In the receiver data view display settings can not be made.

Receive performance (S-dBm): the receive performance is sent “live” to the SMART-BOX via the

receiver’s downlink channel. Note: the receive performance is shown as a negative value, i.e. a value
approaching zero is the maximum (= best reception); the lower the value falls, the worse the receive
performance.
This value is particularly important during the range-check procedure carried out before fl ying the mo-
del.
Please read the corresponding section in the RC system instructions relating to range-checking.
Carry out a range-check before every fl ight, simulating all servo movements which will occur in fl ight: the
range must be at least 50 m on the ground when the transmitter is set to range-check mode; to guaran­tee safe fl ying, the value displayed under S-dBm in the DATAVIEW display should be at least -80 dBm.
If the value is lower (e.g. -85 dBm) you should not even consider fl ying your model: check the receiver
installation and the power supply systems in your model and radio control system.
When operating your model this value should not fall below -90 dBm. If it does, you should reduce the
distance between yourself and the model. However, under normal circumstances the audible range
warning (see below) will be triggered before the value falls to this level, in order to ensure safe ope­rations.

Signal strenght (S-STR): indicates the signal strenght in %.
An audible range warning (continuous beeping at one-second intervals) is always emitted as soon

as the receiver signal in the downlink channel falls to the pre-set threshold. Since the transmitter has a
much higher transmitting power than the receiver, it is still possible to operate the model safely, but in
the interests of security you should always reduce the distance to the model until the audible warning
stops.

Receiver temperature (R-TEMP): it is important that the temperature of your receiver always stays
within the approved range under all fl ight conditions (ideally between 10 and 55°C; please refer to your
RC system instructions).

Manual Module M-G1 33300 06

The limit values for receiver temperature which trigger a warning can be set in the RX SERVO TEST
display under ALARM TEMP+ (50 – 80°C) and ALARM TEMP- (-20 – +10°C).
If the receiver temperature rises above the maximum value or falls below the minimum, the unit genera­tes an audible warning (continuous beeping). At the same time all the Smartbox receiver displays show
a fl ashing “TEMP.E” at top right, and the parameter R-TEM is shown in inverse form in the receiver data
display (RX DATAVIEW).

Data packets (L PACK TIME): indicates the duration of signal loss of the longest data packet during
transmission from transmitter to receiver, stated in msec. In practice this equates to the longest period
which the RC system has spent in fail-safe mode.

Operating voltage (R-VOLT): it is essential to monitor the operating voltage of the receiver constantly.
If it is too low, you must never launch your model or continue fl ying it.
The receiver low voltage warning can be adjusted in the RX SERVO TEST display under ALARM VOLT;
the available range is 3.0 to 6.0 Volt. If battery voltage falls to the threshold level, an audible signal
(continuous beeping) is emitted, and “VOLT.E” fl ashes at top right in all the Smartbox receiver displays.
At the same time the parameter R-VOLT is shown in inverse form in the receiver data display (RX DA­TAVIEW).

Minimum operating voltage (L.R-VOLT): displays the lowest receiver operating voltage since the last
time the receiver was switched on. If this voltage differs signifi cantly from the actual operating voltage
R-VOLT, it is likely that the servos are placing an excessive load on the receiver battery, resulting in vol­tage collapses. If this should occur, you should consider fi tting a larger or more robust receiver battery
in order to obtain maximum operating security.

Telemetry sensor 1 / 2 (SENSOR 1 / SENSOR 2): if these optional sensors are connected, their data
(Voltage / Volt and temperature / °C) is displayed live on the screen.

this display only affect the channel which you select at this point.

Servo reverse (REVERSE): sests the direction of rotation of the connected servo
Normal: REVERSE OFF
Reverse: REVERSE ON

Servo centre (CENTER): The “CENTRE” line displays the current pulse width in μs of the control chan-
nel selected in the “OUTPUT CH” line. The displayed value varies according to the current position of
the transmitter control which affects this control channel, and also its trim position. A pulse width of 1500
μs corresponds to the standard centre position, and therefore the usual servo centre setting.
To change this value, select the “CENTRE” line and touch the INC + DEC buttons simultanously. Move
the corresponding transmitter control to the desired position, and touch the INC + DEC buttons again to
store the current transmitter control position. This position is now stored as the new neutral position.

Trim position (TRIM): The purpose of the “TRIM” line is to provide fi ne adjustment of the neutral po-
sition of a servo connected to the control channel selected in the “OUTPUT CH” line. Adjustments are
made in 1 μs increments using the INC or DEC buttons. The value in the “CENTRE” line can be adjusted
over the range +/- 120 μs around the TRIM value set here.
Servo travel (TRAVEL +/-): this function is used to adjust the maximum servo travel (control surface
travel) of the connected servo. The adjustment is available separately for each direction
Cycle time (PERIOD): at this point it is possible to defi ne the speed of the servos’ response to move-
ments of the transmitter controls. This adjustment applies to all channels.
Note: if you are using analogue servos, you must set a value of 20 msec. If you are using digital servos
exclusively, 10 msec should be selected.

Output channel select (OUTPUT CH): this is where you select the desired channel; the remainder of

Input channel select (INPUT CH): channel mapping function
The control functions can be distributed over several receivers in any sequence; alternatively multiple
receiver outputs can be assigned to the same control function. For example, this is useful if your aircraft

Manual Module M-G1 33300 08

features two servos acting on each aileron instead of only one.
The SMART-BOX can be used to manage a maximum of sixteen transmitter channels. At this point
you can defi ne how the transmitter channels (INPUT) are assigned to the channels (OUTPUT) of the
receiver(s).
If your model is fi tted with multiple receivers, the Master receiver is the last receiver to be bound.
However, in subsequent operations only the receiver which was bound last is able to make a telemetry
connection to the transmitter. On the other hand, this also means that only the last bound receiver can
be addressed using the Telemetry menu.

Fail-safe mode (MODE): this function is used to select the fail-safe mode for the channel you have se­lected. You can select either a programmed fail-safe position (Fail Safe), hold-mode for the last position
(HOLD) or OFF.
But CAUTION: if the control signal is absent, analogue servos and many digital servos offer no resis­tance to the forces acting on the control surfaces, with the result that the model’s control surface posi­tions are more or less quickly lost.

Please read the corresponding chapter in the RC system instructions on this subject.

F.S.Pos. (Fail-Safe position):

For each OUTPUT CH (receiver servo socket) activate (highlight) the value fi eld by briefl y pressing the
INC + DEC simutanously, then use the INC or DEC buttons in the “F.S.POS.” line to set the servo posi­tion which the servo is to take up in “FAIL-SAFE” mode if interference should occur. The setting can be
entered in increments of 10 μs. Default setting: 1500 μs (servo centre).
Important note:
The “F.S.POS.” function is also signifi cant if the receiver is switched on, but is (not yet) receiving a valid
signal; this applies to all three modes “OFF”, “HOLD” and “FAILSAFE”: The servo immediately runs to
the Fail-Safe position previously set in the “Position” line. This can be exploited, for example, to prevent
the operation of a retractable undercarriage or similar function if the receiver is switched on accidentally.
However, during normal model operations the corresponding servo behaves in accordance with the set
“MODE” if interference should strike.

Fail-safe response time (DELAY): this point is used to select the delay time after which the servos run
to their selected position if interference affects the radio signal. This value is applied to all channels.

FAIL SAFE ALL (global fail-safe setting): This sub-menu can be used to defi ne the Fail-Safe position
of the servos simply by “pressing a button”; and is simple to use: Move to the “FAIL-SAFE ALL” line and
press the INC + DEC buttons simultanously to activate the value fi eld; “NO” is highlighted (black back-
ground). Now set the parameter to “SAVE” using the INC or DEC button. Use the transmitter controls to
move all the servos which you have assigned - or intend to assign later - in the “MODE - FAIL-SAFE”
line, to the desired fail-safe positions. In the extreme bottom line “Position” displays the current position
of the transmitter control for the channel you have just set.
After touching the INC + DEC buttons once more, the display reverts from “SAVE” to “NO”. This indica­tes that the position of all the servos affected by the procedure have now been stored, and have also
been adopted in the “F.S.Pos.” line. At the same time the position for the current OUTPUT CH (servo
socket) is immediately displayed on the screen.
Switch the transmitter off, and check the Fail-Safe positions by observing the servo movements.

Fail-safe position (POSITION): displays the Fail-Safe position for the channel set under OUTPUT
CH.

“Fail-Safe” in combination with “channel mapping”

It is clearly desirable that mapped servos - i.e. servos which are controlled by a common control channel
(INPUT CH) - should respond in the same way when interference occurs, so the corresponding settings
of the INPUT CH determine the behaviour of mapped servos.
For example, if receiver servo sockets 6, 7 and 8 are mapped together, i.e. if the same control channel
“04” is assigned to OUTPUT CH (servo sockets) 06, 07 and 08 then INPUT CH 04 determines the Fail-

09 Manual Module M-G1 33300

Safe behaviour of the three servos connected to control channel 4, regardless of the individual settings
of the OUTPUT CH for INPUT CH 04. This also applies, for example, if it is mapped in turn to INPUT
CH 01.
In this case servo socket 04 would respond in accordance with the Fail-Safe settings for CH 01. In con­trast, the response or delay time set in the “DELAY” line always applies uniformly to all channels which

CAUTION: if the receiver is switched on and you call up the fail-safe function again using the program­ming button on the transmitter, any settings previously programmed in the FAIL SAFE display using the

the test by simultaneously pressing the INC / DEC buttons (dark background disappears)

Receiver low voltage warning (ALARM VOLT): monitors the receiver voltage, and can be set to any
value within the range 3.0 to 6.0 Volt. If the voltage falls to the threshold value, an audible signal is
emitted (continuous beeping), and “VOLT.E” fl ashes at top right in all the Smartbox’s receiver displays;
at the same time the parameter R-VOLT is displayed in inverse form in the receiver data display (RX
DATAVIEW).

Receiver temperature monitor (ALARM TEMP +/-): monitors the receiver temperature. It is pos­sible to program both a lower limit value ALARM TEMP- (-20 – +10°C) and an upper limit value

ALARM TEMP+ TEMP (50 – 80°C). If the receiver temperature rises above the maximum value or falls
below the minimum, the unit generates an audible warning (continuous beeping). At the same time all
the Smartbox receiver displays show a fl ashing “TEMP.E” at top right, and the parameter R-TEM is
shown in inverse form in the receiver data display (RX DATAVIEW).

It is important that the temperature of your receiver always stays within the approved range under all
fl ight
conditions (ideally between 10 and 55°C; please refer to your RC system instructions). If the tempera­ture rises above maximum or falls below minimum an audible signal is emitted (continuous beeping)

Channel- (CH OUTPUT TYPE): at this point you can select how the receiver signals are sent to the
outputs.
ONCE: the receiver outputs are transmitted in sequence: recommended for analogue servos. This set­ting ensures that the servos are automatically operated using a 20 msec cycle - 30 msec in the case
of the twelve-channel receiver (Order No. 33512) - regardless of the value set and displayed in the RX

Manual Module M-G1 33300 12

SERVO display under the menu point ‘PERIOD’.

SAME: the receiver outputs are transmitted in parallel blocks of four, i.e. channels 1 to 4 and channels
5 to 8 receive the transmitter signal simultaneously in each case: recommended for digital servos. It is
particularly useful where multiple servos are used for a particular function (e.g. ailerons), so that all the
servos move absolutely synchronously.
It is also possible to connect analogue servos; in this case you must set 20 ms in the menu point ‘PE­RIOD’ in the RX SERVO display.

Note: if you select the SAME setting, it is especially important to install a high-capacity receiver power
supply system, as up to four servos are almost always working simultaneously, placing a greater load
on the battery.

SUMI (Sum signal Input): Input for satellite receiver
SUMO (Sum signal output): the receiver outputs are transmitted in sequence, whereby the highest

channel transmits the sum signal; this signal is required by certain optional devices. With this setting the
servos are automatically operated using a 20 msec cycle - 30 msec in the case of the twelve-channel
receiver (Order No. 33512) - regardless of the value set and shown in the menu point ‘PERIOD’ of the
RX SERVO display.
Ex: V-Stabiliser, teacher-student system, Microbeast, fl ight simulator and output satellite receiver

SATELLITE MODE

Two HoTT receivers are inter-connected using a three-core connecting lead (Order No. 33700.1 (300
mm) or 33700.2 (100 mm) by the highest-numbered servo sockets. For more details on this please visit
www.graupner.de on the Internet.
The HoTT receiver which is confi gured as SUMO (see below) is designated the satellite receiver, and
all its channels are transmitted in the form of a sum signal to the second HoTT receiver - the primary
receiver - if reception should fail; the primary receiver must be programmed as “SUMI”. Note that the
signal only ever moves towards SUMI.
The receiver outputs are addressed in sequence at a frame rate of 20 ms (30 ms with the GR-24 re­ceiver, Order No. 33512), even if you have set 10 ms in the “PERIOD” line of the “RX SERVO” screen
page. However, if the receiver programmed as the satellite (SUMO) suffers signal reception failure, the
servos connected to that receiver take up the Fail-Safe positions programmed in the satellite receiver,
regardless of the primary receiver.
This receiver confi guration is recommended in particular circumstances: for example, if one of the two
receivers has to be installed in an unfavourable position in the model, or if there is a danger that the
received signal will be weak in certain fl ight attitudes, perhaps due to a turbine, carbon fi bre in the
airframe, or a similar problem, with the result that sporadic range problems might be expected.
For this reason it is essential to connect the most important control functions to the primary receiver (the
one programmed as SUMI), so that interference to the satellite receiver (SUMO) does not cause the
model to go out of control. Telemetry data, such as the voltage of the airborne power supply, are only
sent to the transmitter by the satellite receiver (confi gured as SUMO), i.e. all telemetry sensors must be
connected to the satellite receiver (SUMO).
Each receiver should be connected to the shared power supply using its own power lead. If high cur­rents can be expected, duplicated power connections are recommended. However, if each of the two
receivers is to be powered by its own battery, then it is essential to withdraw the central (red) wire from
one of the two satellite lead connectors.
If you wish to carry out further programming, such as the Fail-Safe settings, disconnect the three-core
satellite connection between the two receivers, and switch on just the receiver you wish to address. Note
that you may also need to change the binding sequence.

6. FUNCTIONS

6.1. Binding

When you wish to use the Graupner HoTT 2.4 GHz receiver with a particular transmitter, the fi rst step
must always be to “bind” the unit to “its” Graupner HoTT 2.4 GHz RF module (transmitter). However,
the “binding” procedure is only required once for each receiver / RF module combination. Carry out the
following steps when necessary:

• Switch the transmitter and receiver on.

• Without Smart-Box or internal telemetry: Locate the BIND / RANGE button on the back of the mo-
dule, and hold it pressed in while you press and hold the SET button on the receiver. Both LEDs on
the back of the transmitter now glow constantly, and the red LED on the receiver fl ashes. Under
normal circumstances the fl ashing red LED on the receiver will cease to fl ash and switch to a con-
stant green within about ten seconds. This indicates that the binding process is complete. You can
now release both buttons, and your transmitter / receiver combination is ready for use.

With Smart-Box or internal telemetry:• At the Telemetry menu “TX” go to the RX BIND line, then
press the INC + DEC buttons on the SMART-BOX simultaneously (or push rotary): the screen
changes to BINDING, displayed highlighted (black background). Hold the SET button on the recei­ ver pressed. If the fl ashing red LED on the receiver goes out within about ten seconds, the green
LED glows constantly then the binding procedure has been completed successfully.

• However, if the red LED on the receiver continues to fl ash for longer than ten seconds, then the
binding process has failed. If this should occur, repeat the whole procedure.

6.1.1. Binding multiple receivers in one model

If required, it is also possible to bind multiple receivers to the transmitter for a particular model. The fi rst
step is to bind each receiver individually using the procedure already described.
When the system is in use, the receiver which was switched on fi rst, is the Master receiver. Any teleme-
try sensors installed in the model must be connected to this unit, as only the Master receiver transmits
sensor data using the downlink channel. The second and all further receivers operate in parallel with the
Master receiver but in Slave mode, with the downlink channel switched off.
The control functions can also be distributed amongst multiple receivers; this is carried out using the
Channel Mapping function of the SMART-BOX (Order No. 33700). In the same way it is possible to as­sign one control function to multiple receiver outputs; a typical example would be the use of two servos
for each aileron instead of only one, etc.

6.2. Range checking

The method of checking the effective range of the Graupner HoTT 2.4 GHz system is described below.
We recommend that you ask a friend to help you with this procedure.
After binding the receiver to your transmitter, switch the transmitter and the receiver on, and wait until
the green LED on the receiver lights up.

• Install the bound receiver in the model in its fi nal intended position.

• Switch the RC system on, so that you can observe the movement of the servos.

• Set up the model on a fl at surface (pavement, closely mown grass or earth), and ensure that the
receiver aerials are located at least fi fteen cm above the ground. This may require a support for the
model.

• Hold the transmitter at hip-height, away from your body, but do not point the aerial directly at the
model; instead turn and / or angle the aerial tip so that it stands vertical, and keep it there for the
duration of the range check.

• Start the range check mode in the Telemetry menu; the transmitter starts beeping evenly, and the
red and green LEDs next to the BIND / RANGE button fl ash alternately.

• Walk away from the model, operating the transmitter sticks constantly. If you detect an interruption
in the link within a range of about fi fty metres, stand still and attempt to reproduce it.

• If the model is fi tted with a motor, switch it on in order to check whether the power system is gene-
rating interference.

• Continue to walk away from the model until you reach the point where perfect control is no longer
possible.

• Now press the BIND / RANGE button on the transmitter once more; this terminates range-check
Manual Module M-G1 33300 14

mode manually, and the model should respond normally to control commands. If this does not occur
with 100% reliability, the system should not be used. Contact your local Service Department of
Graupner GmbH & Co. KG.

• Range-check mode is usually terminated manually when the user presses the BIND / RANGE but
ton, but it terminates automatically after about ninety seconds in any case. The red LED now glows
constantly again, while the green LED either glows constantly or fl ashes continuously, according to
the Country setting.

• We recommend that you check effective radio range before every fl ight. While you are carrying
out the check, simulate all the servo movements which will take place when the model is in fl ight.
The ground range must always be at least fi fty metres in order to ensure safe, reliable model con-
trol.

Note:

Range-check mode is usually terminated manually when the user presses the BIND / RANGE button,
but it terminates automatically after about ninety seconds in any case.

CAUTION:

During normal operations (i. e. when controlling a model) never press and hold the programming
button on the transmitter module!

6.3. Fail-Safe function (RX Failsafe)

In its default state (as delivered) the receiver is set to “Hold” mode, i.e. if a fail-safe situation occurs, all
the servos connected to it maintain the last position detected as valid. In this mode the red LED on the
receiver lights up when interference occurs, and the red LED on the transmitter goes out. The transmit­ter also starts beeping about once per second as an audible warning.
You can exploit the safety potential of the fail-safe option by at least programming the throttle channel to
respond to a fail-safe situation: the throttle channel of an engine-powered model should be set to idle,
the throttle channel of an electric-powered model to “stop”, and the throttle channel of a model helicop­ter to “Hold”. You can program the fail-safe function either in the Telemetry menu under “RX Failsafe”
(5.2.3), or on the transmitter module: repeated brief presses of the BIND / RANGE button on the trans­mitter module cycle through the fail-safe modes (fail-safe on / off, hold-mode, or standard).

• Fail-Safe mode: when you press the BIND / RANGE button, the transmitter beeps once; the red
and green LEDs glow constantly.
It is now possible to program positions to which the servos will move in a Fail-Safe situation; this
occurs after a “Hold” period of 0.75 seconds: move the corresponding transmitter controls (sticks,
rotary knobs, INC / DEC buttons etc.) to the desired Fail-Safe positions SIMULTANEOUSLY, then
hold the BIND / RANGE button pressed in for three to four seconds. When you release the button,
both the red and green LEDs should light up constantly, and the transmitter should not emit an au­ dible signal: the transmitter now reverts to Control mode. If this does not occur, repeat the procedu­ re.

• Hold mode (recommended for model helicopters): when you press the BIND / RANGE button,
the transmitter beeps twice; the red LED lights up constantly, and the green LED goes out (factory
default setting).
If interference occurs, all servos programmed to “Hold” remain at the last position detected by the
receiver as correct; this situation is maintained until such time as the receiver picks up a new, valid
control signal.
You can save your selection by holding the BIND / RANGE button pressed in for three to four se­ conds. When you release the button, both the red and green LEDs should light up constantly, and
the transmitter should not emit an audible signal: the transmitter now reverts to Control mode. If this
does not occur, repeat the procedure.

• Fail-Safe OFF: when you press the BIND / RANGE button, the transmitter beeps three times; the
green LED glows constantly, the red LED goes out.
You can save your selection by holding the BIND / RANGE button pressed in for three to four se­ conds. When you release the button, both the red and green LEDs should light up constantly, and
the transmitter should not emit an audible signal: the transmitter now reverts to Control mode. If this
does not occur, repeat the procedure.

• Standard mode (suitable for fi xed-wing model aircraft only): when you press the BIND / RAN-
GE button, the transmitter beeps four times; both LEDs are off.

15 Manual Module M-G1 33300

In this mode the throttle servo (channel 1) moves to the Fail-Safe position, i.e. the position you have
programmed for a Fail-Safe situation, while all the other channels remain at “Hold”.
Move the throttle stick to the desired position, then hold the BIND / RANGE button pressed in for
three to four seconds. When you release the button, both the red and green LEDs should light up
constantly, and the transmitter should not emit an audible signal: the transmitter now reverts to
Control mode. If this does not occur, repeat the procedure.

6.4. Country setting (COUNTRY)

The Country setting is present in order to cater for various directives (FCC, ETSI, IC etc.). The HoTT

2.4 radio system features a restricted frequency band for France. If you wish to use the RC system in
France, the country setting on the transmitter must be set to “France” mode, as described. It is essenti-
al not to use the Universal/EUROPE mode. If you select the “France” setting on your transmitter, you
MUST select it again every time you alter the Fail-Safe settings using the programming button.
You can either program the Country setting in the Telemetry menu “TX COUNTRY” (5.1.) or on the
transmitter module: To select a Country setting, you must fi rst switch the transmitter off, then insert the
(FRANCE / GENERAL) programming plug (supplied) in the DATA socket on the back of the transmitter.
Switch the transmitter on: you can now toggle between the “GENERAL” and “France” settings by briefl y
pressing the BIND / RANGE button, always starting with the current setting.

• GENERAL/EUROPE: the transmitter beeps once when you press the BIND / RANGE button, and
the green LED lights up constantly.
Default setting: approved for use in all countries with the exception of France.

• France: the transmitter beeps twice when you press the BIND / RANGE button, and the green
LED fl ashes continuously.

• Once you have selected the Country setting, save it in the transmitter by holding the BIND / RANGE
button pressed in for about three seconds. When you release the button, the transmitter emits a brief
confi rmation tune, and the beeps cease.

• Switch the transmitter off, and remove the programming plug. Do not under any circumstances use
the radio control system with the programming plug inserted!

• If you subsequently wish to check the current Country setting for the transmitter, observe the green
LED on the back of the transmitter when it is switched on:

green LED glowing constantly = “GENERAL”
green LED fl ashing constantly = “France”

6.5. Low voltage warning

If the transmitter voltage falls below 8.0 V (the voltage can be programmed in the Telemetry display
“TX” or with the Smart-Box), the RF module generates an audible low voltage warning in the form of a
steady series of beeps at intervals of around one second. This occurs independently of the transmitter
software.

6.6. Range warning

If the receiver signal in the down-link channel becomes too weak, the transmitter always generates an
audible range warning in the form of a beep emitted about once per second. Since the transmitter’s
output is much higher than that of the receiver, you will still maintain full control of the model, but in the
interests of safety you should fl y the model back towards you until the warning signal ceases again.
If the audible range warning signal does not cease when you reduce the distance, then the transmitter
or receiver low voltage or temperature warning is active! In this case you must land the model and cease
operations without delay.

6.7. DATA socket - Firmware update or SMART-BOX connection

The SMART-BOX is connected to the USB1-socket on the back of the transmitter, also Firmware up­dates for the transmitter RF module can be transferred via the USB1-socket in conjunction with a PC
running Windows XP, Vista or 7. For this you also require the USB interface, Order No. 7168.6, and the
adapter lead, Order No. 7168.6A, which are available separately.
The programs and fi les required for this are available from www.graupner.de in the Download area for
the corresponding products.
See also chapter 7.

Manual Module M-G1 33300 16

6.8. Data Storage

micro-SD and micro-SDHC

the transmitter can be switched on again.

Data recording / saving

Data storage on the SD card automatically starts after a telemetry connection of the receiver exists, as­suming that a compatible memory card is installed in the card slot - and will stop automatically 2 seconds
after the receiver was turned off.
Note: After switching on the receiver a beep will sound after about 2 seconds and the display „SD card
log“ changes to ON - Data recording starts. After switching off the receiver the beep will sound again
after about 2 s and the display changes to OFF. Then switch off the transmitter so that the log data is
stored. If you turn off the transmitter before the beep / display OFF appears, no log data is saved!
By default, always the transmitter and receiver data (with integrated telemetry) or transmitter only (wit­hout integrated telemetry) are recorded. To log the connected sensor or receiver, go to Start Recording
in the menu „Model Select“ of the Smart-Box and select the connected sensor - with built-in telemetry
transmitters, turn the Rotary from the basic display to the right.
After concluding a data save process you will fi nd a folder entitled “LogData” on the memory card. This
folder stores log fi les which are named according to the following scheme: 0001, 0002.bin etc. (sequen-
tial numbers) in the folder named “No-Name”. The data can subsequently be analysed on a compatible
PC using the PC programs which can be found on the download page for the associated transmitter at
www.graupner.de.

Any standard commercial micro-SD memory card with a capacity of up
to 2 GB can be used, and also any micro-SDHC card of up to 32 GB.
However, the manufacturer recommends the use of memory cards with
capacities up to only 4 GB, as these are completely adequate in all normal
circumstances.
The memory cards for which the transmitter is intended are familiar from
their use in digital cameras and mobile telephones. Place the card in the
slot with the contacts facing to the outside, and push it in until it locks. Now,

6.9. Earphone socket

The vario tones are activated as follows:

- The Vario output can be switched ON or OFF via the transmitter in the „TX“ display under the menu
item „VARIO TONE“ - select ON here.

- Go to the menu „Model Select“ of smart box and select the connected sensor - with built-in telemetry
transmitters, turn the Rotary from the basic display to the right.

The “EARPHONE” socket is designed to accept standard earphones or
headphones fi tted with a 3.5 mm barrel connector (not included).
Signals associated with the Telemetry menu, such as the audible Vario
output, are present at this socket in addition to the transmitter’s audible
signals.

7.1. Update procedure

Ensure that the adapter lead is confi gured as shown in the illustrations, and is connected correctly to
the transmitter or receiver.

Start the Graupner Firmware Update Utility.

Under [COM Port Setup] select the correct COM
port, i.e. the one to which the USB lead is connec­ted. If you are not sure of this, press the button
„Search“ and select in the pop-up window „Silicon
Labs CP210x USB to UART Bridge“ and press „OK“.
Baud Rate: 19200.

Under [Interface Type] click on Signal 2:Vcc3:Gnd.
Now click on the “Browse” button and select the fol­der containing the previously loaded fi rmware fi le
ending in *.bin. If everything is correct, the fi le will
appear in the corresponding window.
The fi rmware fi les are encoded in product-specifi c

form, i.e. if you accidentally select a fi le which does
not match the product (e.g. transmitter update fi le instead of receiver fi le), then the pop-up window “Pro-
duct code error” will appear, and you will not be able to start the update procedure.
Press the “Program” button in the software. Wait briefl y until you see movement in the progress bar. This
may take up to fi ve seconds, depending on the computer.

Transmitter: press the BIND / RANGE button, and switch the transmitter on while you hold it pressed
in.

After a few seconds the Status screen displays the message “Found target device…”; you can now

Manual Module M-G1 33300 18

release the button, and the fi rmware update process commences.
If the device is not recognised, if the pop-up window “Target device ID not found” appears, or if the
process fails before 100% is reached, you must restart the update procedure. Repeat all the steps as
described above.

The Status display and the Progress bar show the progress of
the fi rmware update. The update is completed when the mes-
sage “Complete…100%” or “Complete!!” appears.

During the update process both LEDs on the transmitter glow
constantly. When it is complete, the red LED goes out and you
will hear a brief confi rmation melody. Both LEDs on the receiver
also light up; when the process is complete, the green LED
goes out, and the red LED starts fl ashing.

Switch your transmitter / receiver off, and disconnect the ad­apter lead.

Caution: after completing an update process, you must in­itialise the device before using it, i.e. reset it to the factory
default values.

Initialisation:

To initialise the transmitter, or to reset it to the factory default settings, press and hold the BIND / RAN­GE button on the module while you switch the transmitter on, then release the BIND / RANGE button
again.

Please note:

When initialisation is complete, the transmitter will be in Fail-Safe set-up mode. You can therefore imme­diately continue by programming your fail-safe settings.
If you previously set your transmitter’s Country setting to “France” mode, you must also re-enter the
Country setting.
