GRAUPNER mx-20 Hott

200
Detail program description - Control adjust
Important notices:
Check that the model aircraft is operational •
and check that all functions issue the correct
commands BEFORE setting up trainer mode.
The ends of the trainer lead, usually marked as •
either "S" or "M", terminate in a three-pole TRS
jack. Do not insert these jacks into a DSC system
socket, as it is not suitable for this application.
The DSC socket is exclusively designed for a
trainer lead with 2-pole TRS jacks.
Checking functionality
Activate the assigned trainer mode switch:
The trainer mode system is working properly if the •
display now changes from "Teach" to "Pupil".
If the center LED rapidly fl ashes blue/red, however, •
and the unit beeps at the same time, then the pupil-
teacher transmitter connection has been lost.
The basic display also displays the following warning
notice …
No
pupil
signal
… and the left side of the screen display on the
"Teacher/pupil" menu changes to show "-Pupil".
In this case, all control functions are retained by
the teacher transmitter automatically, regardless of
switch position: this ensures the model is always
under control.
Possible faults:
Pupil transmitter not ready•
Interface in pupil transmitter not correctly connected •
in place of the RF module
Cables connected wrongly: see right for cable •
connections
Pupil transmitter not switched over to PPM (10, 18, •
24) mode
Other possible faults:
Teacher transmitter not properly "bound" to HoTT •
receiver in training model
