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.
Please note: the labeling of the arrows of the following displays corresponds the top buttons on the
SMART-BOX.

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.

Signal quallity (S-QUA): shows the signal quality in %
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.
