Operating Instructions
Frequency band and Channel change
Change frequency band: The Transmitter can be
operated on different frequency bands by changing
the High Frequency module. The removable HF
module is held by four sprung pin fittings in the
centre of the Transmitter. Two cables must be
attached. Link 1 connects to the Transmitter circuit
board. Link 2 connects the HF module to the aerial.
8 General Section
Changes of the HF channels: The channel is
determined by the crystal. Only crystals of the
correct type and the appropriate frequency band may
be used (see page 98).
The Transmitter crystals "T" is put into the HF
module. Frequency band and channel number of the
crystal inserted must correspond with that in the
Receiver.
Installation the Module
The Transmitter case is pre-drilled for the installation
of the modules, like NAUTIC, Proportional and
Switch Module. The blanking caps in the holes of the
case can be removed pushing them outward with an
appropriate object. To complete the assembly of the
Proportional and Switch modules, Part. No. 4152 or
4151, they must be connected to the HF module.
The NAUTIC modules are installed by inserting the
controls through the pre-drilled holes in the case
(from the inside) (see next paragraph "fastening the
modules"). Ensure that the connection socket of
these modules points to the centre of the transmitter.
