Graupner Hendheld RC 2.4 GHz No. of channels: 5 33110 Manual Do Utilizador

88

In theory the Graupner HoTT system permits the simul-
taneous operation of more than 200 models.
However, in practice the mixed operation of different 
technical systems in the 2.4 GHz ISM band - as requi-
red by the approval regulations - reduces this number 
considerably. Generally, however, it will always be 
possible to operate even more models simultaneously 
on the 2.4 GHz band than on the 35 / 40 MHz frequency 
bands which we have used to date. However, the actual 
limiting factor - as it has always been - is likely to remain 
the size of the (air-) space available. The simple fact that 
no frequency control procedure is necessary - a great 
convenience in itself - equates to an enormous gain in 
safety, especially at fl ying sites where groups of pilots 
may be distributed over a large area, with nobody in 
overall control.

Battery charged?
When you take receipt of your transmitter, the battery 
will be in the discharged state, so you must fi rst charge 
it as described on page 81. Otherwise you will hear a 
warning signal and the Status-LED fl ashes fi ve times in 
quick succession when falling below a certain voltage to 
remind you to recharge it.
This warning threshold for the transmitter battery can be 
selected in the menu „TX“ of the optional the Smart Box, 
page 114.

After switching on the Status-LED glows constantly or is 
blinking to indicate the current transmitter mode.
See the following table:

Preliminary notes regarding the 

mx-10 HoTT transmitter

To change the mode, move the mode switch on the 
transmitter in the desired position, press and hold the 
BIND-button and then switch on the transmitter.
Note: after programming the „normal“ mode, the trans-
mitter is in fail-safe programming mode (see page 111), 
if you do not want to program anything here, turn off the 
transmitter again now.
The programmed mode is indicated with LED and 
buzzer signals after switching on the transmitter, see the 
table above.

Transmitter battery empty. Hit the battery warning 
threshold, 4.5 V as standard, set in the menu „TX“ of 
the optional Smart-Box, page 114

First select the transmitter mode „normal“, „teacher“ or 
„pupil“ by the transmitter mode switch on the left top side 
of the transmitter:

 

The transmitter is delivered in the mode „normal“. For 
normal operation you have to change nothing. In order 
to select the teacher or pupil mode, read the chapter 
„Trainer model“ on page 127.
