CONTROLS AND THEIR FUNCTIONS

( 2 ) ®
1. HF POWER/"S" METER: This
Light Emitting Diode (LED) meter
shows the Radio Frequency power
when
transmitting and the
strength of the incoming signal
when receiving.
2. CHANNEL INDICATOR: Light
Emitting Diode (LED) indicates the
channel number in use.
3. PRESS-TO-TALK MICRO­
PHONE: The receiver and trans­
mitter are controlled by the press-
to-talk switch on the microphone.
Press the switch to activate the
transmitter; release the switch to
receive. When transmitting, hold
the microphone two inches from
the mouth and speak clearly in a
normalvoice. The microphone pro­
vided with your radio is a detach­
able low impedance dynamic type.
4. OFF/VOL, CONTROL: Turn
clockwise to apply power to the ra­
dio and to set the audio volume to
the desired listening level. Turn
fully counter clockwise to turn the
radio OFF.

SQUELCH CONTROL; This
Squelch Control is rotated to cut off
or eliminate received background
noise in the absence of an incoming
signal. For maximum receive sensi­
tivity, it is desired that the control
be rotated only to this point where
the receive background noise or
ambient background noise is elimi­
nated. Turn the control fully coun­
ter clockwise, then slowly rotate
clockwise until the receive noise
disappears. Any signal to be heard
must now be slightly stronger than
the average received noise. Further
clockwise rotation will increase the
threshold level which a signal must
overcome in orderto be heard. On­
ly strong signals will be heard at the
maximum clockwise setting.
ANl/OFF SWITCH: When placed
in the ANL position the Automatic
Noise Limiter circuit is activated.
The ANL circuit reduces impulse
noise.
CHANNEL SELECTOR SWITCH:
This switch selects the desired
channel for transmission and recep­
tion. All channels, except channel
9, may be used for communications
between stations operating under
different license, Channel 9 has
been reserved by the D.O.C. for
emergency communications involv­
ing the immediate safety of individ-
uals or immediate protection of
property. Channel 9 also may be
used to render assistance to a mo­
torist. This in a D.O.C. rule and ap­
plies to all operators of citizens
band radios,
8. TX INDICATOR; Light Emitting
Diode (LED) which indicates the
mode of operating. It indicates red
while transmitting.
9. ANTENNA CONNECTOR: This
female connector permits connec­
tion of the transmission line cable
male connector (PL-259) to the
transceiver.
10. POWER CORD; A power cord is
supplied with the radio.

11. EXTERNAL SPEAKER: The Exter­
nal Speaker Jack is used for remote
receiver monitoring. The external
speaker syould have 8-ohm imped­
ance and be rated to handle at least
4.0
watts. When the external
speaker is plugged in, the internal
speaker is automatically discon­
nected.
