Uniden MC 724 - Manual (Page 3)

IIViSTALLATfON
CAUTION: The IVIC 724 will operate only with a nominal 12 volt negative
ground battery system.
CHOOSING A LOCATION
1. Select a location that is free from spray and splash.
2. Select a location that minimizes exposure to direct sunlight {including that com­
ing through windows).
3. Select a location that allows free air flow around the heatsink on the rear of the
radio,
4. Select a location well away from the ship's compass. Auxiliary speakers also
should be located away from the compass.
5. Select a location as close to the battery as possible (in order to keep battery leads
as short as possible). Direct connection to the battery is most desirable. If direct
connection cannot be made with the supplied power lead, any extension should
be made with at least #10 AWG wire.
ENGINE NOISE SUPPRESSION
Interference from the impulse noise generated by the electrical systems of engines is
sometimes a problem with radios. The MC 724 has been designed to be immune to
ignition impulse noise and alternator noise. However, in some installations it may be
necessary to take measures to further reduce the effect of noise interference. All DC
battery wires, antenna leads and accessory cables should be routed away from the
engine and engine compartments and from power cabling carrying particularly high
currents.
;
In severe cases of impulse noise interference, it may be necessary to install a noise
suppression kit that is available from your UNIDEN Dealer.
ANTENNA CONSIDERATIONS
1, Keep the antenna lead as short as possible. Long antenna leads can cause substan­
cial loss of performance for both receiving and transmitting.
2. Locate your antenna as high as possible and clear from metal objects. The reliable
range of coverage is a direct function of antenna height. The general rules for
antennas are: The more gain the greater the range and, the higher above the water
line the greater the ranger.
MOUNTING CONSIDERATIONS
Keep in mind the flexibility designed into the MC 724 so that you can most con­
veniently use your radio. The points which should be considered are:
1, Universal mounting bracket may be installed on either top or bottom for shelf
bulkhead, or overhead mounting,
'2. The microphone connector faces forward allowing convenient in-dash or "built-
in" installations.
