Operating instructions

Manual Module M-G1 33300 16
• 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.
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 up-
dates 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.
