en into account. You must select the opti

mum relationship among these consider
ations.

ently use your radio. Features which should

mended you draw upon the advice of your
Marine Dealer in determining a suitable
antenna for your vessel and range require
ments.

CHOOSING A LOCATION

Some of the more important external fac
tors to consider in selecting the location of

your MC610 are:

1. Select a location Is free from spray and
splash.

2. Keep the battery leads as short as possi
ble. Connection directly to the battery is
most desirable, If direct connection can
not be made with the supplied power
lead, any extension should be made
with #J0 AWG wire. Long extensions
should use larger wire,

3. Keep the antenna lead as short as possi
ble. Long antenna leads can cause sub
stantial loss of performance for both re
ceiving and transmitting,

4. Locate your antenna as high as possible
and clear from metal objects. The reli
able range of coverage is a direct func
tion of antenna height.

5. Select a location that does not allow the

radio to be subjected to direct sunlight
(including that coming through win

dows).

The general rules for antennas are; The
more gain the greater the range and, the
higherabove the water line the greater the
range. Antennas should be located so as

not to be in proximity to metal objects. An
tennas should not have excessively long
coaxial feed cables.

7. Select a location well away from the
ship"s compass. Auxiliary speakers also
should be located away from the com

pass.

Afteryou have carefully considered the var

ious factors affecting your choice of loca
tion, position the radio [with the bracket,
microphone, power plug, antenna plug
and any auxiliary plugs installed) into the
selected location to assure, there is no in
terference with surrounding items, Mark
the location of the mounting bracket.

Remove the bracket from the radio and use
it as a template to mark the holes to be
drilled for the mounting hardware. Drill the
holes and mount the bracket with hard
ware compatible with the material of the
mounting surface. Install the power cable
(red is -k, black is—), antenna and all other

auxiliary cables and accessories.

Install the radio into the mounting bracket
and connect all cables and accessories to
the appropriate jacks and connectors.

6. Select a location that allows free air flow
around the heat sink on the rear of the

radio.
