INSTALLATION
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 recommended that you install only a qaaiity^ntenna in your new citizens band
system. You have just purchased a superi^ transceiver. Don’t diminish its performance
by installing an inferior antenna. *
Only a properly matched antenna system will allow maximum power transfer from the 50ohm transmission line tolfie ^diating element. Your Uniden dealer is qualified to assist
you in the selection'of the prt^>цr antenna to meet your application requirements.
ATTACHMENT QF HANDSTRAP
.A mounting hqle is i>rovided above the PTT switch on the left of the unit. If you wish to use
the handstrap, apply the tip of the metal ring of the strap to this hole and attach by rotating
k. Se&the illustration below.

ATTACHMENT OF BELT SUSPENDER
If you wish to use a belt suspender, attach it with the 2 screws provided on the rear panel as
illustrated below.

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.

1. CHANNEL LAMP SWITCH: If desired to know proper channel No. in the night opera
tion. turn on this switch, the channel light will light and be able to read it out clearly.
2. PRESS-TO-TALK SWITCH: This will changeover the mode to either transmit or re
ceive. Depress it to fall in the transmit mode, and release to return to the receive mode.
3. POWER HI-LOW SWITCH: This selects the RF output power. In High mode, the output
power is 2.5W (rated output) and LOW 350mW.
In LOW mode, power consumption is decreased to enable a long hours of operation.
For a short distance communication, it is suggested to operate on low power.
