INSTALLATION
MOBILE STATION INSTALLATION
Plan the location of the transceiver and microphone bracket before starting the installa-
tion. Select a location that is convenient for operation and does not interfere with the driver
or passenger in the vehicle. The radio should be securely fastened to some solid face, us-
ing the mounting bracket and self-tapping screws which are provided.
MOBILE STATION 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. You have just purchased a superior transceiver. Don't diminish its performance
by installing an inferior antenna.
Only a properly matched antenna system will allow maximum power transfer from the 50-
ohm transmission line to the radiating element. Your Uniden dealer is qualified to assist
you in the selection of the proper antenna to meet your application requirements.
For automobile installation, the whip antenna may be used with good effect. The most effi-
cient and practical installation is a full quarter wave whip antenna mounted on the rear
deck or fender top midway between the rear window and bumper.
A short "loaded" whip antenna is more convenient to install on your automobile, although
the efficiency is less than a full quarter wave whip antenna.
For marine installation, consult your dealer for information regarding an adequate ground-
ing system and prevention of electrolysis between fittings in the hull and water.
GROUND SYSTEM
Connect the red DC power cord from the transceiver to the positive, or (+), battery terminal
or other convenient point and con nect the black power lead to the chassis or veh icle frame,
or (-) battery terminal.
SELCALL
SELCALL (Selective Calling) is a special Squelch System which quiets your receiver until
it receives an Encoded signal from another set which matches the one installed in your set.
This means your set will remain quiet and not receive idle chit chat or other signals until the
station you want to hear calls.
SELCALL is not initially installed in your set (each one has to be individually programmed)
but may be purchased as an option.
