19 Description of transmitter
Note:
Whenever you intend to work on the interior
of the transmitter, remember to disconnect the
transmitter battery from the power socket.
Take great care not to touch soldered joints with
any metallic object, as this could cause a short-
circuit.
It does not matter which way round you connect the
external switches.
Reversing the orientation of the control connector
simply reverses its direction of effect.
Synthesizer RF module:
The channel is selected in the software when you
switch the transmitter; see page 22.
For safety reasons the RF module can only be swit-
ched from the 35 / 35B MHz to the 40 / 41 MHz band
(or vice versa) by an authorised
GRAUPNER Service
centre.
