156 Program description: Trainer system
The Pupil transmitter must always be operated in •
PPM mode, regardless of the type of RF link be-
tween the Teacher transmitter and the model.
If the Pupil transmitter is connected using a DSC
•
socket, then you should ALWAYS leave the Pu-
pil transmitter’s On / Off switch at the “OFF” posi-
tion, as this is the only way to ensure that the Pu-
pil transmitter module does not generate an RF
signal even when the DSC lead is plugged in.
Trainer mode operations
Connect the two transmitters using the appropriate
lead; see the overview on the next page: connect the
plug marked “
M
” (Master) to the socket on the Teacher
transmitter, and the plug marked “
S
” (Student) (not
present on all leads) to the appropriate socket on the
Pupil transmitter.
Important notes:
It is essential to check that all functions are •
transferred correctly to the prepared model BE-
FORE initiating Trainer mode operations.
If you are using a Trainer lead with three-pole bar-
•
rel connectors, on no account connect one of the
ends marked “S” or “M” to a DSC system sock-
et, as it is not suitable for this purpose. The DSC
socket is only suitable for leads fitted with two-
pole barrel connectors.
Checking the system
Operate the assigned Trainer transfer switch:
If the screen display changes from „ •

T“ to „

P“, the
Trainer system is working properly.
However, if the central LED flashes blue / red at a
•
high rate, and at the same time the transmitter emits
audible signals, then there is a problem with the con-
nection between Pupil and Teacher transmitter.
At the same time the following warning appears in
the base display …
no
student
signal
… and in the “ Trainer ” menu the display changes to
“-P” on the left. If this should happen, note that all the
functions automatically remain under the control of
the Teacher transmitter, regardless of the position of
the Trainer transfer switch; this ensures that the mod-
el is not out of control at any time.
Possible errors:
Pupil transmitter not ready •
The interface in the Pupil transmitter, which replaces •
the RF module, is not connected correctly
Incorrect cable connection: see next section for cable
•
selection
Pupil transmitter not set to PPM (10, 18, 24) mode.
•
Further possible errors:
Teacher transmitter and HoTT receiver in trainer •
model not correctly “bound”.
