PREPARATION  
CONNECTING AN ANTENNA  
Caution: To prevent damage to your walkie-talkie, you must  
connect an antenna before you operate the walkie-talkie.  
Your walkie-talkie comes with a helical antenna that is ideal for  
most applications. However, the walkie-talkie’s BNC antenna  
connector makes it easy to connect other types of antennas.  
Your local Radio Shack store sells a wide variety of antennas.  
Choose the one that best meets your needs.  
Follow these steps to connect an antenna.  
1. Position the BNC antenna connector over the antenna jack  
on the walkie-talkie.  
2. Slip the slot in the antenna connector over the antenna  
jack’s tab on top of the walkie-talkie.

• Do not dispose of the batteries in a fire because they can  
explode.  
• Do not open or mutilate a battery. Swallowing a battery can  
be fatal.  
• Be careful not to short the batteries with conducting materi-  
als, such as rings, bracelets, and keys. The batteries or  
conductor might overheat and burn.  
• At the end of a rechargeable battery’s useful life, it must be  
recycled or disposed of properly. Contact your local,  
county, or state hazardous waste management authorities  
for information on recycling or disposal programs in your  
area. Some options that might be available are municipal  
curbside collection, drop-off boxes at retailers such as your  
local Radio Shack store, recycling collection centers, and  
mail-back programs.  
Charging Nickel-Cadmium Batteries

rechargeable batteries. Charging non-rechargeable batteries  
can cause them to become very hot and possibly explode.  
Notes:  
You can recharge the batteries with the battery case at-  
tached to the walkie-talkie, but be sure to turn off the  
walkie-talkie before you charge them.  
• Charging time is 14 to 16 hours the first time. Subsequent  
recharging takes about 8 to 10 hours.  
• Occasionally, let the nickel-cadmium batteries totally dis-  
charge by using the walkie-talkie until BATTLOWappears  
on the display. Then fully charge the batteries. This condi-  
tions the batteries so they use their full charging capacity.  
Caution: To prevent permanent nickel-cadmium power loss,  
never charge the batteries in an area where the temperature is  
above about 90°F.

OPERATIONAL HINTS  
Like most activities, CB radio has its customs and courtesies.  
The following tips will help you get the most enjoyment from your  
walkie-talkie.  
COMMON USES FOR A CB RADIO  
Business Uses  
• Truck drivers and delivery personnel can learn road and  
traffic conditions and get assistance in locating destina-  
tions. 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 coordinat-  
ing the activities of different work crews.  
• For security officers, a CB radio is more than a conve-  
nience — it is a must for both safety and efficiency.  
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.

21-1672.fm Page 28 Thursday, August 5, 1999 12:04 PM  
• If you are a two-car (or more) family, CB radios are great  
for communicating with family members while they are in  
their cars.  
• Contact friends or neighbors — find out “what’s happening”  
or plan a get-together.  
• Ever have car trouble or run out of gas on the highway?  
What 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.  
TRANSMISSION COURTESY  
• Wait for a pause in someone else’s transmission before  
you ask for a break.  
• If you do not receive an answer to your call after a second  
attempt, sign off and wait several minutes before trying  
again.  
• Do not hold down the PTT button when you are not talking.  
(This is called dead keying.)  
• Assist callers with directions, information about road condi-  
tions, and any other reasonable requests.

21-1672.fm Page 29 Thursday, August 5, 1999 12:04 PM  
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’s mounting location — the higher  
the antenna, the better the signal’s range  
• The surrounding terrain — mountains and tall buildings  
limit range  
• Weather conditions  
• The number of nearby radios operating on the same chan-  
nel  
Note:  
Your CB radio’s transmission range is generally line-of-  
sight. To ensure maximum range, always keep fresh or fully-  
charged batteries in your CB radio.  
USING COMMON 10-CODES  
Citizen’s band operators and CB radio users have largely adopt-  
ed the 10-codes for standard questions and answers. These  
codes permit faster communication and better intelligibility in  
noisy areas.

CARE  
Your Radio Shack TRC-232 4-Watt 40-Channel CB Walkie-  
Talkie is an example of superior design and craftsmanship. The  
following suggestions will help you care for the CB radio so you  
can enjoy it for years.  
• Keep the walkie-talkie dry. If it gets wet, wipe it dry immedi-  
ately. Liquids can contain minerals that can corrode the  
electronic circuits.  
• Handle the walkie-talkie gently and carefully. Dropping it  
can damage circuit boards and cases and can cause the  
walkie-talkie to work improperly.  
• Use and store the walkie-talkie in normal temperature envi-  
ronments. Temperature extremes can shorten the life of  
electronic devices, damage batteries, and distort or melt  
plastic parts.  
• Keep the walkie-talkie away from dust and dirt, which can  
cause premature wear of parts.  
• Wipe the walkie-talkie with a damp cloth occasionally to  
keep it looking new. Do not use harsh chemicals, cleaning  
solvents, or strong detergents to clean the walkie-talkie.  
Modifying or tampering with the CB radio’s internal components  
can cause a malfunction and might invalidate the CB radio’s  
warranty and void your FCC authorization to operate it. If your  
CB radio is not performing as it should, take it to your local Radio  
Shack store for assistance.

FCC INFORMATION  
The Federal Communications Commission (FCC) does not re-  
quire you to have a license to operate this CB radio. However,  
you must know Part 95 of FCC Rules. It explains the proper op-  
eration of a Class D citizens band transceiver. We enclosed a  
copy of Part 95 with your CB radio.  
Warning:  
Do not open the CB radio to make any internal adjust-  
ments. A CB radio is set up to transmit a regulated signal on an  
assigned frequency. It is against the law to alter or adjust the set-  
tings inside the unit to exceed these limitations. Any adjustments  
to a CB radio must be made by a qualified technician using the  
proper test equipment.  
To be safe and sure:  
1. Never open your CB radio’s case.  
2. Never change or replace anything in your CB radio.  
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 interfer-  
ence goes away, your CB radio is causing the interference. Try  
to eliminate the interference by:  
• Moving your CB radio away from the receiver  
• Contacting your local Radio Shack store for help

This device complies with Part 15 of FCC Rules. Operation is  
subject to the following two conditions:  
1. This device may not cause harmful interference.  
2. This device must accept any interference received, includ-  
ing interference that may cause undesired operation.  
REPLACING THE DC  
CAR ADAPTER FUSE  
The DC car adapter has a 32V 2-amp fuse in the cigarette lighter  
plug. When replacement is required, use a slow-blow glass fuse,  
such as Cat. No. 270-1023.  
1. Turn the cap on the adapter plug counterclockwise to un-  
screw it from the plug body.  
2. Remove the old fuse and inspect its condition. If it is  
“blown” and requires replacement, insert a new 2-amp  
fuse. If it is not “blown,” reinsert it.  
3. Replace the spring, the terminal, and the cap and screw  
the cap in tightly.
