FCC INFORMATION
The Federal Communications Commission
(FCC) does not require you to have a license
to operate this CB radio. However, you must
know Part 95 of
ply to the operation of a Class D CB. We
have provided a copy of these regulations
with your CB radio.
FCC Rules
. These rules ap-
Warning
make any internal adj us tme nts . A CB rad io is
set up to transmit a regulated signal on an
assigned frequency. It is against the law to
alter or adjust the settings inside the unit to
exceed these limitations.
To be safe and sure:
Your CB radio might cause TV or radio interference even when it is operating properly.
To determine whether your CB radio is causing the interference, turn off your CB radio. If
the interference goes away, your CB is causing it. Try to eliminate the interference by:
If you cannot eliminate the interference, the
FCC requires that you st op usin g your CB radio.
: Do not open your CB radio to
• never open your CB radio’s cases.
• never change or replace anything in
your CB radio.
• moving your CB radio away from the TV
or radio
• contacting your local RadioShack store
for help
This device complies with Part 15 of

MOUNTING THE CB
The most co mmon mount ing loc ation for t his
CB is under a veh ic le’ s das hb oard . Ho w ev er,
if you use the CB as a base station in your
home or office, you can place it on a desk,
shelf, or table (see “Using the CB as a Base
Station” on Page 7).
To mount the holder near the receiver in another location in your vehicle (such as a
dashboard), or somewhere in your home or
office, such as a nearby wall, follow these
steps.
1. Using the holder as a t emplate, m ark the
positions for the screw holes at the
desired location.
2. At each marked position, drill a pilo t hole
slightly smaller than the mounting
screws.
Installation
If you are mounting the CB in a vehicle,
choose a location where:
• you can easily reach the CB
• wires and cables are clear of the vehicle’s pedals and other moving parts
• the CB is not directly in front of heating
vents
• all wires and cables can reach their connection point

: If you use the CB in a vehicle,
mount it securely to avoid damage to the CB
or vehicle o r injury to pa ssengers.
Follow these steps to mount the CB using
the supplied hardware.
1. Using the mounting bracket as a template, mark the positions for the screw
holes on the mounting surface.
2. In each marked location, drill a pilot hole

CONNECTING AN ANTENNA
There are many different types of antennas
for mobile CBs, each with its own benefits.
You can choose one that best fits your
needs, available at your local RadioShack
store.
Note
: If you are us in g thi s C B as a ba se sta tion, see “Using the CB as a Base Station”
on Page 7.
When you choose an antenna, keep in mind
that, for the best performance, you should
mount the antenna:
• as high as possible on your vehicle,
home or building
• as far as po ssible fr om sources of electrical noise
Note
: If you cannot reach behind the
mounting surface to attach the nuts on
the bolts, use the

Cautions
To take advantage of your radio’s maximum
range, adjust the antenna’s Standing Wave
Ratio (SWR) using an SWR meter, available
at your local RadioShack store.
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.
:
• Avoid routing the cable next to sharp
edges or moving parts wh ich m ight d amage the cable.
• Do not run the cable next to power
cables or other radio antenna cables.

USING THE CB AS A BASE
STATION
Although this CB radio is des ign ed m ai nly for
mobile use, you can also use it as a base
station with an AC power source. For base
station installation, you need these items:
7
21-1705.fm Page 8 Thursday, September 7, 2000 10:41 AM
• a 13.8V DC power supply that supplies
at least 1.5 amps (available from
RadioShack)
Caution
: Most 13.8V DC power supplies plug into a standard AC outlet to
produce DC power. Before connecting
your CB to a 13.8V DC power supply,
read and follow the instructions included
with the power supply.
• base station antenna (available from
RadioShack)
• coaxial antenna cable and connector
(available from RadioShack)
Warning
: 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 the 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 remove it yourself!
Follow these steps to install the CB as a
base station.
4. Connect the CB’s red wire to the positive (+) terminal on the DC power supply.
5. Connect t h e D C pow e r su pp l y t o a s tan dard AC outlet.
Cautions
:
• To comply with FCC RF exposure compliance requirements, maintain a distance of at least 20 cm between this
device’s antenna and all persons.
• To prevent damage to the CB, be sure
you connect an antenna and the microphone before you use the CB.

COMMON USES FOR A CB
Personal Uses
• Keep in touch with home while driving to
work, to the store, or to a social activity.
Let your family know you are tied up in
traffic, or that you will stop by the store
on the way home .
• If you are a two-car (or more) family, CB
radios are gr eat for co mmunicati ng with
family members while they are in their
cars.
• Contact friends or neighbors — find out
“what’s happening” or plan a gettogether.
• Ever have car trouble or run out of gas
on the highway? W hat an assurance it is
to be able to radio for assistance!
• Camping, fishing, and other sports are
more fun with a CB radio. Locate a
buddy or find out “what’s cooking” back
at camp.
Business Uses
• For security officers, a CB is more than
a convenience — it is a must for both
safety and efficiency.

Note
: Your CB radio’s transmission range is
generally line-of-si ght.
REDUCING NOISE
Note:
Operation instructions are for satisfy-
ing FCC RF exposure requirements.
Because your CB is exceptionally quiet, any
noise you hear is probably from an external
source in your vehicle such as an alternator,
another radio, or spark plugs.
The transceiver uses an ANL (Automatic
Noise Limiter) circuit to reduce noise. However, if poss ibl e, try to eli min ate the noi se 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 (or
ON). If the noise is reduc ed, the problem is in
your vehicle’s ignition or electrical system.
Your local RadioShack store has a wide selection of noise-suppression accessories.
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 grou nd c onn ec tion 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.

Care and Maintenance
To enjoy your RadioShack 40-Channel MiniMobile CB Radio for a long time:
• Keep the CB dry. If it gets wet, wipe it
dry immediately.
• Use and store the CB only in normal
temperature environm ent s.
• Handle the CB gently and carefully. Do
not drop it.
• Keep the CB away from dust and dirt.
• Wipe the CB with a damp cloth occasionally to keep it looking new.
Modifying or tampering with the CB’s internal
components can cause a malfunction and
might invalidate its warranty and void your
FCC authorization to operate it. If your CB is

REPLACING THE FUSE
The CB’s 2-A in-line fuse helps protect your
CB (and vehicle) from power surges and
short circuits. Replace a blown fuse with a 2A, slow-blow glass fuse, available at your local RadioShack store.
2. Hold the fuse holder by both ends, push
the ends together, twist one end counterclockwise, then pull them apart.
3. Remove the old fuse and inspect its
condition. If it is not blown, rein sert it. If it
is blown, insert a new one of the same
type and rating.
4. Push the fuse holder ends together and
twist one end clockwise.
