Operation Manual

CAUTION:
• This setting must be left unchanged all the time you are using
teacher/pupil mode. „PUPIL ON“ must remain active!
• Do not disconnect the teacher/pupil lead from either transmitter
while you are using teacher/pupil mode!
5. Ending the teacher/pupil mode
Press the 3D-digi-adjustor once. The cursor moves back to the upper line and
the teacher/pupil lead can be disconnected from the transmitters.
Note:
If the two transmitters are disconnected during operation
the pupil transmitter remains in pupil mode. When switched on the transmitter
does not show the operating screen (as usual), but the PUPILs menu set to ON. If
this happens press the 3D-digi-adjustor to quit the pupil mode and select the oper-
ating display.
10. Channel-Check gives security when you switch on
The Channel-Check module is a monitor receiver which checks the channel on
which your transmitter is operating. It can be installed in the transmitter at any
time.
Every time you switch the transmitter on, the monitor receiver is automatically acti-
vated and checks whether your channel is vacant. If the channel is already in use, or
is encountering interference, the indicator lamp on the transmitter glows red, and
the RF section stays switched off. This means that you do not run the risk of operat-
ing your own model, and you will not cause interference to the other model which
could already be flying within a radius of about 300 m from your location.
10.1. Installing Channel-Check
1. Fit a receiver crystal in the Channel-Check module as shown in
the drawing alongside.
Important:
The channel numer of the crystals for the Channel-Check
module and the receiver (in the model) must be identical.
MULTIPLEX receiver crystals are fitted with a yellow plastic
sleeve and are printed with the code letter „E“ before the
channel number.
2. Open the transmitter case (Fig. I)
3. Hold the module by the narrow sides and place it carefully on the Channel-
Check socket on the main circuit board (Fig. V)
Check that the two rows of pins on the main circuit board engage correctly in
the sockets.
4. Close the transmitter case
