You can return to the basic display on both screens and
start the training session after carefully checking all of
the relevant functions.
If neither transmitter or only one transmitter displays
"ON", this means the binding process has failed: try
changing the positions of both transmitters and then
repeat the entire procedure.
Important notice:
Check that the model aircraft is operational and
check that all functions issue the correct commands
BEFORE setting up trainer mode.
During the ...
Training session
... the teacher and pupil can maintain a more "relaxed"
distance from one another. The "reach of signal"
(max. 50 m) should not be exceeded under any
circumstances, however, nor should anyone else be
standing between the teacher and the pupil, since these
204 Detail program description - Control adjust
persons could reduce the connection range of the return
channel used by the two transmitters. Furthermore, you
should remember that the return channel assigned for
wireless trainer mode functionality is normally used for
telemetry connections: accordingly, it will not be possible
to transmit any model telemetry data.
In this operating mode, the basic display of the teacher

transmitter is as shown below ...

... and the pupil transmitter's display will look something
like this:

If, however, the connection between the teacher and
pupil transmitters should be lost during the training
session, then the teacher transmitter will automatically
assume control of the model.
If the trainer mode switch is in the "Pupil" position when
connectivity is lost, then the center LED on the teacher
transmitter will fl ash blue/red while the signal is lost and
audible warning signals will also be given. The basic
display also displays the following warning notice:

If only the character string "HF –" starts fl ashing on
the transmitter's basic display, however, and (quieter)
audible warning signals are given, the pupil signal has
still been lost, but the trainer mode switch is set to the
"Teacher" position.
In both cases, your fi rst step should be to reduce the
distance between the two transmitters. If this does not
help, then you should land immediately and establish
the cause.
If both transmitters are operational and the receiver
system is switched off, then the teacher transmitter's
basic display will show the "familiar"
two icons . The antenna icon will also fl ash and an
audible warning signal will sound twice per second.
Resuming trainer mode
If you switch off one or both transmitters during the
session – for whatever reason – then the basic display
of the transmitter(s) shows the following question after
being switched back on:
Please select
trainer link?
ACT INH
If you either confi rm "INH" by tapping the center
key on the right touch pad, or alternatively wait for
approx. two seconds until the message disappears,
then you will reset the transmitter in question back to
its "normal" operating mode. You will then have to re-
establish a connection between the teacher and pupil
transmitters.
