User's Manual

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”
2.5. Low voltage warning
If the transmitter voltage falls below 8.0 V, 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.
2.6. 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.
2.7. Firmware update or SMART-BOX connection
The SMART-BOX is connected to the DATA socket on the back of the transmitter.
Firmware updates for the transmitter RF module can be transferred via the DATA or telemetry interface
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.

3. Receiver
3.1 Connections
Plug the servos into the row of sockets on the right-hand end of the receiver. The connector system is
polarised; note the small chamfer on one edge. Never use force - the plugs should engage easily and
fully. The socket polarity is also marked on the case: brown wire (-), red (+) and orange (signal).
The servo sockets of the Graupner-HoTT 2.4 receiver are numbered. The socket marked “- +/B” is
intended for the battery. If necessary, a servo can be connected to this socket in parallel with the power
supply; a Y-lead (Order No. 3936.11) is required for this.
