OWNER’S MANUAL — Please read before using this equipment.  
Thank you for purchasing a RadioShack 40 Channel Mobile  
CB. Your CB is a great way to communicate with other CB  
radio operators. You can mount it in a vehicle for mobile  
use, or in your home for use as a base station.

There are many different types of CB antennas for mobile  
CBs. Each type has its own benefits, so choose the one that  
best meets your needs. Your local RadioShack store sells a  
wide variety of antennas.  
."%#76+10".  
Avoid routing the cable next to  
sharp edges or moving parts,  
which might damage the cable.  
When you choose an antenna, keep in mind that, for the  
best performance, you should mount the antenna: .#  
• as high as possible on the vehicle  
• as far as possible from sources of electrical noise  
• vertically  
Do not run the cable next to  
power cables or other radio  
antenna cables.  
Do not run the cable through  
the engine compartment or  
other areas that produce  
extreme heat.

To take advantage of your radio’s maximum range, adjust  
the antenna’s Standing Wave Ratio (SWR) using an SWR  
meter (not supplied).  
Follow the instructions supplied with the SWR meter and  
antenna to adjust your antenna’s SWR to the lowest  
possible value. SWR values of 2.0:1 are generally  
acceptable, with readings of 1.5:1 or lower being more  
desirable.

Using  
Use extreme caution when you  
install or remove a base station  
CB antenna. If the antenna starts  
to fall, let it go! It could contact  
overhead power lines. If the  
antenna touches a power line,  
contact with the antenna, mast,  
cable, or guy wires can cause  
electrocution and death. Call the  
power company to remove the  
antenna. Do not attempt to do so  
yourself!

You can easily view your current heading at a glance. There  
are eight cardinal points on the display — north, northeast,  
east, southeast, south, southwest, west, northwest.  
Calibration helps the compass better separate the earth’s  
magnetic field from the magnetic field generated by external  
influences (such as your vehicle), providing more accurate  
heading information.

Before calibration, end CB  
transmission and make sure the  
CB is not tuned to the  
Emergency channel 9 or 19 or  
in PA mode.  
Calibrate the compass anytime you move it, or whenever  
distortion continuously appears. Before calibration, peel off  
the backing on one side of the supplied tape and attach the  
tape to the back of the compass, then mount the compass  
by peeling off the backing on the other side of the tape, then  
press the compass onto the level mounting surface, with the  
compass’ arrow facing up and pointing to the front. Do not  
mount the compass upside down.  
Do not calibrate the compass  
near metal or a strong magnetic  
field.  
The compass is not available in  
TX mode.  
1. Hold down CAL for a second. All eight cardinal points  
flash.  
2. Drive your vehicle in two complete circles. Be sure your  
vehicle is on level ground, in an open area, such as a

3. Press CAL to confirm calibration  
You must complete the circles on level ground and press  
CAL within 10 minutes. Or, start from Step 1 again.

Because your CB is exceptionally quiet, any noise you hear  
is probably from an external source in your vehicle such as  
the alternator, another radio or spark plugs.  
The transceiver uses an ANL (Automatic Noise Limiter)  
circuit to reduce noise. However, if possible, try to eliminate  
noise by finding its source.  
You can determine the noise’s source by turning off the  
engine and operating the CB with your vehicle’s ignition set  
to ACC. If the noise is reduced, the problem is in your  
vehicle’s ignition or electrical system.  
Here are a few hints to help you reduce or eliminate such  
noise:  
• Make all CB power and antenna wires as short as  
possible.  
• Route the power wires away from the antenna wires.  
• Be sure that the chassis ground connection is secure.  
• Replace old ignition wires with new, high-voltage, noise  
suppression wires.  
• Install noise suppressors on your spark plugs, or install  
new spark plugs that have built-in noise suppressors.  
• If problems persist, check your alternator/generator and  
regulator gauges. You can reduce the noise from these  
sources by using bypass capacitors at the various  
output voltage points.  
Your local RadioShack store has a wide selection of noise  
suppression accessories.
