Uniden MC-4300 manual Connecting The Power Cords, Operating Procedure To Receive, Antenna

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 properly 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 SOU ELCH 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.
