4 INSTALLATION

4.1 VHF installation

34
The radio should be sited so that engine noise and vibration or
other background noise do not make it difficult for the operator
to hear.
Although the RD68 radio is waterproof when flush mounted, it
is recommended that it is not installed where it will be exposed
to continuous direct sunlight, as this will eventually damage
the LCD display.
As microphones and loudspeakers contain powerful magnets,
the radio should not be installed within 1m (3ft 3in) of any
compasses, whether magnetic or electronic.
The fins on the back of the case act as a heatsink to dissipate
heat generated by the set when in use, which maintains the
high efficiency of the radio. The free circulation of air is essen-
tial - if mounting the radio in an enclosed space, ensure that the
space is vented.
Desktop mounting
Fig 4.1 - Standard mounting options
The VHF is supplied with a reversible mounting bracket. This
can be used to mount the VHF on the chart table or on an over-
head bulkhead (Fig 4.1). The bracket is fixed in place using
four No.10x3⁄4 screws (supplied). Before installing, ensure that
there is at least 88mm (3.5 in) vertical clearance and 70mm
(2.8in) horizontal clearance behind the bracket to allow the
radio to fit (Fig 4.2).
