7.1.2 Handset Installation
The handset should be sited so that engine noise and vibration
or other background noise do not make it difficult for the oper-
ator to hear.
As microphones and loudspeakers contain powerful magnets,
the handset and speakers should not be installed within 1m
(3ft 3in) of any compasses, whether magnetic or electronic.
The handset is connected to a 5m (16.5ft) extension cable, there-
fore the handset should be fitted within reach of the transceiver
box (for longer runs, 20m extension cables are also available as
separate accessories - see section 8.6).
The handset cradle should be mounted on a flat surface with
enough space to allow the bulkhead socket for the extension
cable to be fitted alongside. Space should also be allowed near-
by for the accompanying loudspeaker to be fitted.
NOTE
The handset and bulkhead socket are waterproof, but if the
handset is to be fitted in an exposed location (for example on
the flybridge of a power boat) it is recommended that the
handset and especially the bulkhead socket is fitted to an
angled or vertical surface to prevent standing water lying on
the handset face or inside the bulkhead socket, which could
corrode the pins.
Fit the supplied template for the handset cradle to the desired
mounting location. Drill 4 x3.2mm (0.125in) pilot holes in the
indicated positions. If drilling into GRP, it is recommended
that the holes are also countersunk to prevent the gelcoat split-
ting when the self-tapping screws are inserted.
Fit the supplied template to the desired mounting location for
the bulkhead socket. Drill a 23.5mm (0.94in) hole and 4 x
2.4mm (0.1in) pilot holes. Again, the pilot holes should be
countersunk if drilling into GRP.
Fit the bulkhead socket and run the cable to the transceiver box
position.
NOTE
It is recommended that the cable is routed away from any other
cables carrying high current (eg mains power cables) or pulsed
signals (eg transducer cables) to avoid possible interference.
If the handset is being removed, the waterproof cover should
always be fitted to the bulkhead socket to protect the pins from
possible corrosion.
