OPERATING INSTRUCTIONS
IMPORTANT: Make sure antenna, power source, and micro-
phone are connected before you operate.
TO RECEIVE
1. Connect MICROPHONE and depress MANUALPOWER ON-OFF
push buttonto turn unit ON. Rotate VOLUMEto increase loudness.
You cannot transmit or receive if MICROPHONEis disconnected.
2. Set CB/PA switch to CB position.
3. Set ANTENNA
switch to the antenna connected,
A or B.
4. Turn CHANNEL SELECTOR to any of the 40 channels as indi-
cated by the LED readout window.
5. Select the desired operating FUNCTION, either AM, LSB or USB.
When it is placed in AM, the unit transmits and receives as any
conventional transceiver.
SSB is only intelligible if both you and the other operator are in the
same USB or LSB position. When transmitting, the sideband you
select (LSB or USB) will interfere with AM stations on that channel.
They also hear you, though not intelligibly. When receiving LSB or
USB, use the RAPID and FINE TUNE CLARIFIER controls.
6. Turn SQUELCH counterclockwise to activate the receiver circuit,
and a hissing sound will be heard in the speaker. Slowly rotate
SQUELCH clockwise until the hissing just stops.
The RF/S METER reading will indicate incoming signal strength.
Experiment with SQUELCH setting to become familiar with the
signal strenoth of unit ("S" units on r.leter) which overrides
SQUELCH setting. To receive only strong, clear signals, set
SQUELCH to high position, but to monitor all transmissions, set it
to minimum position. (When weak or no transmissions are being
received, continuous atmospheric noise will be heard. If noise is
objectionable, turn SQUELCH to point where noise just stops.)
7. Turn TONE control to suit your listening taste.
8. Use NOISE BLANKER, ANL, or RF GAIN features as requir~d.
TO TRANSMIT
1. Wait until the channel you selected is clear. Hold the MI-
CROPHONE directly in front of you at a distance of about 2 or 3
inches. Now, press in the MICROPHONE push button and talk in a
normal voic.e to transmit your message.
NOTE: Do not shout into the microphone or hold MIC against your
mouth, to prevent over-modulation. Over-modulation is referred to
as sounding like "marble mouth" (garbled).
2. Flip METER switch to MOD position, then read your modulation in
the MODULATION/SWR METER. METER reading will increase
with your voice loudness.
3. Use SPEECH COMPRESSION and MIC POWER to increase
average modulation as desired.
4. TO RECEIVE, release the microphone push button.
5. The NOISE BLANKER, ANL, CLARIFIER, VOLUME, SQUELCH,
TONE, RF GAIN, and SWR CAL control settings have no effect
when transmitting.
6. To turn the transceiver off, depress the MANUAL POWER
ON-OFF button to the "UP" position.
NOTE: Do not press and hold MIC switch without talking, as you
are sending signal with no information (modulation) and are
causing illegal interference to other users.

ANTENNA WARNING INDICATOR
If you have trouble in your antenna system, the AWl light will glow.
When this light is "ON" your antenna or connecting cable is not
connected, badly mis-matched (high SWR), or damaged.
AWl works
only in the AM position and METER switch on the MOD position.
AWl light will go on when SWR reading is between 3:1 and 7:1 or
worse, depending on antenna installation. AWl will also light on some
channels or all channels when using a magnetic antenna. This is
normal because SWR reading with magnetic antenna often exceeds
3:1. If AWl lights on some channels but not on all channels, the SWR is
high on only those channels. As long as reception and transmissions
are acceptable, no action need be taken by the user. Some antennas
(in a particular location) are just not tuneable below a 3:1 SWR
reading.
NOTE: In some situations, the combinations of a particular CB,
antenna, plus the antenna mounting location will result in a low AWl
threshold below 2:1 SWR. Transmitting with AWl lighted does not
degrade performance. If you have this combination, check SWR.
Tune antenna for the most frequently used channel for reading below
2:1 (no AWl light).
DIGITAL CLOCK READOUT
The Digital Clock Readout has two functions. It displays the regular
a.m. or p.m. time and the TIMER setting.
SET THE TIME
In regular operation, the Time Display shows the a.m. or p.m. time. To
set the time:
1. Depress the CLOCK SET push button.
2. Experiment with the clock display by pressing and holding down
first the FAST and then the SLOW TIME SET controls. Become
familiar with the speeds involved and practice setting the clock to
different times.
Use the FAST button to change hours and press the SLOW button
as you approach the a.m. or p.m. setting you want.
Notice that the clock operates on a 24-hour cycle. The A.M. INDI-
CATOR light to the left will show whether the clock is reading a.m.
(light ON) or p.m. (light ON) time.
3. Depress the CLOCK SET control to OFF (UP) position.
SET THE TIMER
To display the TIMER setting, depress the TIMER SET push button.
1. Use FASTand/or SLOW push buttons to set the display to the a.m.
or p.m. time you choose. The AUTOMATIC POWER time is now
"entered" into the timer memory.
2. Release the TIMER SET push button. The correct time is once
again displayed.
AUTOMATIC POWER (TIMER) OPERATION
1. To have the unit turn on automatically at a preset time, set the
TIMER as described above.
2. Depress AUTOMATIC (AUTO) POWER push button.
3. Turn VOLUME knob to increase loudness. The CB will automati-
cally turn on at the time you have set and will turn itself off after
about one hour. To turn CB off sooner, depress AUTOMATIC
POWER push button to OFF (up) position.
Your CB has a 24-hour timer. When left in AUTOMATIC POWER
mode, it willturn itself on, stay on for an hour, turn itself off, and
turn on again at the same time the following day.
