12.1.2 Handset installation
The handset should be sited so that engine noise and vibration,
or other background noise does not make it difficult for the
operator 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 mag-
netic 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; please refer to section 13.8).
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 for
the accompanying loudspeaker to be fitted nearby.
NOTE The handset and bulkhead socket are waterproof. However, if
the handset is to be fitted in an exposed location (e.g. on the
flybridge of a power boat), it is recommended that the handset,
and especially the bulkhead socket, are 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 four 3.2mm (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 splitting
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 four
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 (e.g. mains power cables), or
pulsed signals (e.g. transducer cables) to avoid possible inter-
ference.
If the handset is being removed, the waterproof cover should
always be fitted to the bulkhead socket to protect the pins from
possible corrosion.
