1. MIC(Microphone)GAINControl- Use to adjust themicrophone gain during
transmitting. At the maximum setting, you have full talk power duringtransmitting
while holding the microphone at a comfortable distance. In the PA (Public
Address) mode, this control adjusts the output volume of thePA speaker.
2. VOl(Volume)Control- Use to turnthe power on or off, and to adjust the
receiving audio level.
3. sa (Squelch)Control- Use to eliminatebackground noise during the absence of a
signal. Turn the Squelch Control fully counterclockwise, then slowlyrotate it
back clockwise until all noise disappears. At this setting, any signalmust be
slightly strongerthan the background noise to break squelch and be heard.
Rotating the control farther clockwise increases the threshold level below which
weak signalsare not heard. At the maximum clockwise setting, only the strong
signals can break squelch and be heard.
4. RFGAINControl- For normaloperation, keep the RF Gain Control at the full
.clockwise position. Turn counterclockwise to reduce incoming signal gain when a
signal is strong enough to saturate your receiver.
5. SWRCAl Control- Use to calibrate the meter for SWR (standing-wave ratio)
measurements. Make sure the Mode Selector (7) is set to the AMposition. Turn
the Meter Selector (6) to the CAlposition. Press and hold the microphone PTT
(push-to-talk) Switch. Turn the SWR CAL Control to adj~st the needle to the ...
position on the SWR meter. Then turn the Meter Selector to the SWRposition to
measure the standing-wave ratio of your antenna system. A lower reading
indicates better antenna matching.
6. Meter(SlRFCAl SWR)Selector - Use to selectthe function of the meter. For
normal operation, always set to the SIRF position. The SWR and CAl positions are
for SWR measurement only. (See "Multi-Function Meter" on page 7 for related
information.)
7. Mode (lSB AMUSB) Selector - Use to select the mode of operation (AM,LSB, or
USB) for both the transmitter and receiver. In SSB (single-side band) mode you
are allowed to transmit 12 watts PEP power. Therefore, you can communicate at
far greater distances than with conventional AM mode operation. Because not all
the CBers are equipped with SSB mode, you can always select AM mode for
nQrmal CB communications. (For more details, see" About SSB" in the Operation
section.)
8. CLARIFIERControl- Usetofme-tunetheSSBreceivingsignals.TheClarifier
Control is provided primarily for SSBmode operations. It can alsobe used in AM
mode operation to optimize receiving signals.

9. Channel Selector - Turn this knob to select anyone of tbe 40 channels desired
The selected cbannel is displayed on tbe LED readout, directly above the cbannel
selector knob. Use Cbannel9 for emergency communication only. Because
Cbannel 9 is reserved for emergency operation only, you cannot transmit on this
channel for non-emergency purposes. However, you may momtor Cbannel 9
anytime you wisb to do so.
Important: All channels, except Channel 9, may be used for nor-
mal communication. Channel 9is reserved for emergency com-
munications involving the immediate safety of individuals or the
protection ofproperty.
10. Multi-function Meter -Tbis meter bas three separate functions:
.S-meter
.RPmeter
.SWR meter
For a description of tbese functions, see 'Multi-Function Meter' on page 7.

11. NB and ANL Switch -Activates noise reduction circuitry. At the ANL (Automatic
Noise Limiter) position, only ANL circuitry is activated in the audio to reduce
background white noise. At the NB/ANL position, this switch activates both the
ANL and NB (Noise Blanker)circuitry in the receiver. The NB circuitry is very
effective for repetitive impulse noise, such as ignition noise. In the OFFposition,
NB and ANL circuits are deactivated.
12. CBlPA Switch- For normal CB operation, keep this switch at the CBposition. If
you connect a PA (Public Address) speaker (optional) to the PA. SP. Jack on the
rear panel, set the switch to the PAposition. This enables you to use the radio as a
public address system. In PA mode, your voice will be heard through the PA
speaker. Also, all incoming signals will be heard through the PA speaker. This
allows you to monitor your channel activity while you are outside your vehicle.
Adjust the PA speaker output volume with the Microphone Gain Control.
13. HIILOW Switch -This switch allows you to select the tone of the receiving voice
in the audio. The LOW position increases bass. The HI position increases treble.
14. BRTIDIMSwitch -This switch allows you to change the brightness of thechannel
LED and meter lighting. The DIM position lowers the brightness, and may be more
suitable for night driving.
15. Rxn'XIndicator-This 2-color LED lights to indicate the RX (receivemode) or
TX (transmit mode). The LED is GREENfor RX, and RED for TX. The LED turns
off when pressing themicrophone PTT Switch in the PA mode.
16. Channel Readout -This bright LED displays the selected chamiel number.
Microphone Jack - Connect the microphone to this jack in order to operate either the
receiver or transmitter. If the microphone is not connected, you will hear no audio from
the speaker.
Microphone -Setthe Microphone Gain Control to the full clockwiseposition. Press
and hold the PTT (push-to-talk) Switch, and hold the microphone several inches away
from your mouth. Speak into the microphone clearly in a normal voice. When you are
fmished talking, release the PTT Switch immediately toreceive the responding trans-
mission.

18. P.A.(PublicAddress)SpeakerJack-Connect an optionalPublic Address speaker
here. For the PA speaker, use an 80 speaker with at least a 4-watt rating. Be sure
the PA speaker is directed away from the microphone to avoid acoustic feedback.
When you are operating the PA system with high output level, greater separation
and acoustic isolation between the microphone and PA speaker may be required to
prevent feedback. When this unit is used as a public address system, set the
CB/PA Switch to the PAposition.
19. EXT.SP.(ExternalSpeaker)Jack-Connect an optional external speakerhere. For
the external speaker, use an 80 speaker with at least a 4-watt rating. When an
external speaker plug is connected to this jack, it automatically disables the internal
speaker. This jack is provided for high performance remote receiver monitoring.
20. POWERConnector- Connect the suppliedDC power cord here. The DC power
cord has a mating plug attached to ensure the proper polarity connection. This
easy-to-detach feature is useful whenever the unit needs to be stored in a secure
place.

the location will not interfere with your driving. In a passenger car, the ideal
installation is underneath the dashboard on the passenger side.
2. Remove the mounting bracket from the radio and use it as a template for
marking the location of the mounting screws. (Note: If there are screws
already holding the dashboard, you may be able to use the same screw holes to
mount the bracket.)
3. Drill the necessary holes and secure the mounting bracket in place usmg the
screwsprovided.
4. Mount the radio to thebracket only after the wiring has been connected tothe
rear panel and the microphone hanger has been installed.
MountingtheMicrophoneHanger
Mount the microphone hanger to the side of the radio. Mounting holes are provided
near the microphone connector and on the other side of the unit. Use the screws sup-
plied. You can also mount the hanger on the dashboard, if preferred.
ConnectingthePowerCord
1. Check the vehicle battery connections to detennine which battery tenninal
(positive or negative) is grounded to the engine block or chassis. Most of
today's vehicles use a negative ground. If your vehicle has a negative ground,
follow steps 2 and 3.
2. Connect the REDwire of the DC power cord to the accessory contact in your
vehicle's +13.8 VDC fuse box.
3. ConnecttheBLACKwire of the DC power cord to the negative sideof the
automobile (usually the chassis).
Note: In vehicles with a positive ground, the RED wire connects to the
chassis and the BLACKwire connects to the accessory contact in the
fuse box.
4. Plug the DC power cord into the Power Connector on the rear panel.
