5. Select a location that does not allow the radio to be subjected to direct sunlight
(including that coming through windows),
6. Select a location well away from the ship's compass. Auxiliary speakers also
should be located away from the compass,
ANTENNA
Since the maximum allowable power output of the transmitter is limited by the
D.O,C„ the antenna is a very important factor affecting transmission distance. It is
for this reason that we strongly recommend that you install only a quality antenna in
your new citizens band system.
Only a property matched antenna system will allow maximum power transfer from
the 50-ohm transmission line to the radiating element. Your Santronic dealer is
qualified to assist you in the selection of the proper antenna to meet your applica­
tion requirements.
NOTE: A non shunt-fed antenna must be used for good weather channel reception.
The general rules for antennas are: The more gain the greater the range and the
higher above the water line the greater the range. Antennas should be located so as
not to be in proximity to metal objects. Antenna should not have excessively long
coaxial feed cables.
CONNECTING THE POWER CORDS
After you have carefully considered the various factors affecting your choice of
location, 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
interference 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
hardware compatible with the material of the mounting surface. Install the power
cable (red is +, 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.
OPERATING PROCEDURE TO RECEIVE
1. Be sure that the power source, antenna and microphone are connected to the
proper connectors before going to the next steps.
2. Turn the unit ON by rotating the Volume Control clockwise,
3. Set the Channel Selector Switch to the desired channel.
4. Set the Volume Control to a comfortable listening level.
5. Listen to the background noise from the speaker. Turn the Squelch Control
slowly clockwise until the noise JUST disappears (no signal should be present).
Leave the control at this setting. The SQUELCH is now properly adjusted. The
receiver will remain quiet until a signal is actually received. Do not advance the
control too far, or some of the weaker signals will not be heard.
