88 Using the transmitter for the fi rst time
Preliminary notes
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.
Switching the transmitter on
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.

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.
