12 INSTALLATION
12.1 Physical installation
The RS81/RS82 is a modular radio system that is very simple
to install. However, the performance of the radios is directly
affected by the quality of the installation. Please read these
instructions carefully before attempting installation. If in any
doubt, consult a qualified marine electronics engineer.
12.1.1 Transceiver installation
The RS80B transceiver unit should be installed in a concealed
location such as in a locker or behind the switch panel.
WARNING The transceiver unit is not waterproof, it must therefore not
be installed in any location where it is likely to be exposed to
excess moisture (e.g. a wet locker or an outside locker).
The fins on the top of the transceiver act as a heatsink to dissi-
pate heat generated by the set when in use, which maintains
the high efficiency of the radio. The free circulation of air is
essential – if mounting the transceiver in an enclosed space,
ensure that the space is well ventilated.
The transceiver requires a flat surface with an area of at least
170 x 245mm (6.8 x 9.8in) for mounting. Allow sufficient space
beneath the unit for cable entry – at least 50mm (2.0in) is rec-
ommended. The surface should be rigid and sturdy enough to
be able to support the weight of the unit, taking into account
the shock loads likely to be encountered when the vessel is
underway in heavy seas.
Fix the transceiver unit to the surface using the four self-tap-
ping screws supplied. The four fixing points are at the corners
of the transceiver unit – the bottom two are underneath the ter-
minal cover (Fig 12.1).
