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
Note: If you are using this CB as a base station, see “ Using the Transceiver as a Base Station".
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
Once you choose an antenna , follow its mounting instructions. Then route the cable to the
transceiver and connect the cable to the ANT jack on the back of the transceiver.
Cautions:
. Avoid routing the cable next to sharp edges or moving parts, which might damage the cable.
. Do not run the cable next to power cables to other radio antenna cables.
. Do not run the cable through the engine compartment or other areas that produce extreme heat.
To achieve 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 012 0 : 1 are generally acceptable, with readings
of 1.5:1 or lower being more desirable.

. 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 CE is more than a convenience -- it is a must for both safety and
, efficiency.
. Truck drivers and delivery personnel can learn road and traffic conditions and get assistance
in locating destinations. A CB radio is also good company on those "long hauls."
. On construction crews. a CB radio quickly pays for itself when you are calling for additional
materials or coordinating the activities of different work crews.
Maximum Range
The maximum range and quality of CB radio transmissions vary depending on the following
conditions:
. The type and quality of antenna used
, The height of the antenna’ mounting location -- the higher the antenna, the better the signal's
range
. The surrounding terrain -- mountains and tall buildings limit the range
. Weather conditions
. The number of nearby radios operating on the same channel
. Standing wave ratio (SWR) between the antenna and the CB
Note: Your CB radio's transmission range is generally line-of—sight.
Transmission Courtesy
Please follow these guidelines of radio courtesy when using your CB
. What for a pause in someone else's transmission before you ask for a break.
. "you do not receive and answer to your call after a second attempt. sign off and wait several
minutes before trying again. u
, Do not hold down the Talk button when you are ‘not talking. (This is called dead keying.)
.Assist callers with directions. information about road conditions, and any other reasonable
requests ‘T

Reducing Noise
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 the noise by finding its source.
You can determine the noise's source by turning oil 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 law hints to help you reduce or eliminate such noise:
. Make all CB power and antenna wires as short as possible.
FCCID: AA021—1704
Cannot select a
channel
. 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 gauses. You can reduce
the noise from these sources by using bypass capacitors at various output voltage points.
Your local Radioshack store has a wide selection of noise suppression accessories,
Care and Maintenance
Your RaoioShack TRC-XXX 40-Chennel CB Mobile Transceiver is an example of superior
design and craftsmanship. The following suggestions will help you care for your CB so you
can enjoy it for years.
Keep the CB dry. If it gets wet. wipe it dry immediately. Liquids can contain minerals that
can corrode electronic circuits.
Handle the CB gently and carefully. Dropping it can damage circuit boards and cases and can
cause the CB to work improperly.
Use and store the CB in normal temperature environments. Temperature extremes can
shorten the life of electronic devices, damage batteries. and distort to melt plastic parts.
Keep the CB away from dust and dirt, which can cause premature wear of parts.
Wipe the CB with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals,
cleaning solvents, or strong detergents to clean the CB.
Modifying or tampering with the 08's intemai components can cause a malfunction and might
invalidate its warranty and void your FCC authorization to operate it. if your GB is not performing
as it should, take it to your local Radioshack store for assistance.
Replacing the Fuse
The TRC-XXX‘s Z-amp in—iine fuse helps protect your CB from power surges and short Circuits.
— When replacement is required, use a 2-amp, slow-blow glass tuse.
Follow these steps to replace the fuse.
1. Make sure the power source and CB are both off.
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 blown and requires replacement, insert
a new one of the same type and rating, if it is not blown, reinsert it.
4. Push the fuse holder ends together and twist one end clockwise.
