Installation
Caution: The POLARIS will only operate with a nominal 12 volt
negative ground battery system.
It is important to carefully determine the most suitable location for your
POLARIS on your vessel. Electrical, mechanical, and environmental
considerations must all be taken into account. You should select the
optimum relationship among these considerations.
Keep in mind the flexibility designed into the POLARIS so that you can
most conveniently use your radio. Features which should be considered
are:
1. The universal mounting bracket may be installed on either the top
or bottom of a shelf, on a bulkhead, or for overhead mounting.
2. The REMOTE speaker wires can be used with an auxiliary
speaker.
3. All connections are "plug-in" type for easy removal of the radio.
4. Front fire internal speaker allows convenient in-dash mounting
using the optional bracket (FMB321).
Choosing a Location
Some important factors to consider in selecting the location for your
POLARIS.
1. Select a location that is free from spray and splash.
2. Keep the battery leads as short as possible. Direct connection to
the battery is most desirable. If direct connection can not be
made with the supplied power lead, any extension should be
made with #10 AWG wire. Long extensions should use larger
gauge wire.
3. Keep the antenna lead as short as possible. Long antenna leads
can cause substantial loss of performance for both receiving and
transmitting.
4. Locate your antenna as high as possible and clear from metal
objects. The reliable range of coverage is a direct function of the
antenna height.
5. Select a location that allows free air flow around the heat sink on
the rear of the radio.
6. Select a location well away from the ship’s compass. Auxiliary
speakers also should be located away from the compass.
