9. INSTALLATION

1. The Set Installation

The radio should be sited so that engine noise and vibration or other background noise does
not make it difficult for the operator to hear.
It is recommended that it is not installed where it will be exposed to continuous direct sun-
light, as this will eventually damage the LCD display.
As microphones and loudspeakers contain powerful magnets, the radio should not be in-
stalled within 1m (3ft 3in) of any compasses, whether magnetic or electronic.
The fins on the back of the case act as a heat sink to dissipate 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 radio in an enclosed space ensure that the space is vented.
The MC 6800 DSC Radio is supplied with a reversible mounting bracket. This can be used to
mount the radio on the chart table or on an overhead bulkhead (Fig A). The bracket is fixed in
place using four screws (supplied). Before installing, ensure that there is at least 88mm(3.5
in) verticals clearance and 127mm (5in) horizontal clearance behind the bracket to allow the
radio to fit (Fig B). The rake angle of the radio can be adjusted by slackening the clamp.
