MIC GAIN CONTROL:
This control adjusts the microphone
gain in the transmit mode. This feature is designed for use in a
high-ambient noise environment or to maximize talk power.
11.
SWR SWITCH:
This switch is used to check SWR.
12.
CHANNEL SELECTOR:
This control is used to select a
desired frequency.
13.
SCAN SWITCH:
This switch is used to scan frequencies in
each band segment. The operation section of this manual provides
detailed information on using the scan control.
14.
CLARIFIER CONTROL:
Allows variation of the receiver
operating frequency above and below the selected frequency.
Although this control is intended primarily to tune in SSB signal,
it may be used to optimize AM/FM signals as described in the
operating procedure paragraph.
15.
MEMORY SWITCH:
This is used to program memory
channels.
16.
SQUELCH CONTROL:
This control is used to control or
eliminate receiver background noise in the absence of incoming
signal. For maximum receiver sensitivity, it is desired that the
control be adjusted only to the point where the receiver
background noise is eliminated. Turn fully counterclockwise,
then slowly clockwise until the receiver noise disappears. Any
signal to be received must now be slightly stronger than the
average received noise. Further clockwise rotation will increase
the threshold level that a signal must overcome in order to be
heard. Only strong signal will be heard at a maximum clockwise
setting.
17.
ENTER SWITCH:
This is used to program frequencies into
memory.

VOLUME:
Permits you to adjust the listening level when
receiving.
19.
LOCK SWITCH:
This switch is used to lock a selected
frequency.
20.
MODE CONTROL:
This control allows you to select one of
six following operating modes FM/AM/LSB/USB/CW/PA.

•
DOWN SWITCH:
This switch is used to move frequency
downward to select a desired frequency.
22.
PHONE JACK:
Used to connect earphone to listening.
23.
RF/SWR METER:
This meter operates during transmit only. It
reads power output or SWR.
24.
SIGNAL/MODULATION METER
: This meter indicates
signal strength of incoming signals during receive and your
percentage of modulation when transmitting in the AM.
Modulation readings are most accurate when using maximum
output power. The modulation meter does not work at all in FM
or SSB.
25.
DIM SWITCH:
This switch adjusts the display backlighting
in four different steps to best match environment.
26.
NB/ANL SWITCH:
The noise Blanker is very effective in
eliminating repetitive impulse noise such as ignition interference.
In the ANL position, the automatic noise limiter is active.
27.
ROGER BEEP SWITCH:
When this switch is placed in the
ROGER BEEP position, the radio automatically transmits an
audio tone at the end of your transmission so that people who are
having trouble hearing you will know that you are done speaking.
As a courtesy to others, use the Roger Beep only when necessary.
28.
SPLIT SWITCH:
This switch enables you to split operating
frequency for FM repeater operation.
