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.

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

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,

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.

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

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.

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.
