21-1620.fm Page 12 Thursday, August 5, 1999 11:16 AM
4. When charging is complete, unplug
the battery charger’s plug from the
AC outlet. Then, disconnect the bat-
tery charger’s barrel plug from the
POWER jack.
Note: You can use an external charger
(such as Cat. No. 23-134, not sup-
plied) to recharge the nickel-cadmium
batteries. After removing the batteries
from the TRC-235, follow the instructions
that come with the external charger.
Important: Your TRC-235 is capable of
using nickel-cadmium batteries. At the end
of the batteries’ useful life, they must be re-
cycled or disposed of properly. Contact
your local, county, or state hazardous
waste management authorities for informa-
tion on recycling or disposal programs in
your area. Some options that might be
available are: municipal curbside collec-
tion, drop-off boxes at retailers such as
your local RadioShack store, recycling col-
lection centers, and mail-back programs.
USING VEHICLE BATTERY
POWER
You can power your TRC-235 from your
vehicle’s cigarette-lighter socket with an
optional 12-volt DC fused power cord
(such as Cat. No. 270-1533).
• You must use a DC fused cord that
supplies 12 volts and delivers at
least 1000 milliamps of vehicle
power. Its center tip must be set to
positive, and its plug must correctly
fit the TRC-235’s POWER jack. The
recommended fused cord meets
these specifications. Using a fused
cord that does not meet these speci-
fications could damage the TRC-235
or the fused cord.

rel plug into the POWER jack.
4. Plug the power cord’s other end into
your vehicle’s cigarette-lighter sock-
et.
Note: If the TRC-235 does not oper-
ate when you use the DC power
cord, unplug the cord from the ciga-
rette-lighter socket and clean any
ashes or debris from the socket. If
your TRC-235 still does not work,
check the fuse in the DC power cord
and replace it if necessary.
USING AC POWER
You can power your TRC-235 from stan-
dard AC power using an optional 12-volt
AC adapter that provides 1 amp, such as
RadioShack Cat. No. 273-1653.
Cautions:
• The adapter must be able to deliver
12 volts and at least 1 amp, its cen-
ter tip must be set to positive, and
the barrel plug must correctly fit the
TRC-235’s POWER jack. The recom-
mended adapter meets these speci-
fications. Using an adapter that does
not meet these specifications could
damage the TRC-235 or the adapter.

EXTERNAL ANTENNA
Your walkie-talkie comes with a telescop-
ing antenna that is ideal for most applica-
EXT
tions. However, the walkie-talkie’s
ANTENNA
jack makes it easy to connect
other types of antennas, too. For mobile
or base station use, you might want to
connect an optional external antenna.
Your local RadioShack store carries a
wide selection of external mobile or out-
door base-station antennas. Choose the
one that best meets your needs.
When deciding on a mobile or base-
station antenna and its location, consider
the following:
• The location of the antenna should
be as high as possible.
• The antenna and antenna cable
should be as far as possible from
sources of electrical noise (appli-
ances, other radios, and so on).
• The antenna should be vertical for
the best performance.
Notes
:
• When connecting an optional an-
tenna, always use 50-ohm coaxial
cable, such as RG-58 or RG-8. For
lengths over 50 feet, use RG-8 low-
loss dielectric coaxial cable. If the
coaxial cable’s connector does not fit
EXT ANTENNA
into the
also need
jack, you might
a
PL-259-to-phono
antenna plug adapter, such as Cat.
No. 278-208. Your local RadioShack
store carries a wide variety of coaxial
antenna cable and connectors.

21-1620.fm Page 16 Thursday, August 5, 1999 11:16 AM
• For the best performance when you
use an external antenna, do not
extend the TRC-235’s telescoping
antenna.
Follow the installation instructions sup-
plied with the antenna, route the antenna
cable to the TRC-235, then connect it to
the EXT ANTENNA jack.
Cautions:
• Do not run the cable over sharp
edges or moving parts.
• Do not run the cable next to power
cables or other CB antenna cables.
• Do not run the cable through a vehi-
cle’s engine compartment or other
areas that produce extreme heat.
• Follow all cautions and warnings
included with the antenna.
Warning: When installing or removing a
base station CB antenna, use extreme
caution. 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 do so
yourself.

CB OPERATION TIPS
The following tips will help you get the
most enjoyment from your TRC-235.
COMMON USES FOR A CB
RADIO
Business Uses
•
•
•
Truck drivers and delivery personnel
can learn road and traffic conditions
and get assistance in locating desti-
nations. A walkie-talkie is also good
company on those “long hauls.”
On construction crews, a walkie-
talkie quickly pays for itself when you
are calling for additional materials or
coordinating the activities of differ-
ent work crews.
For security officers, a walkie-talkie
is more than a convenience — it is a
must for both safety and efficiency.
Personal Uses
•
Keep in touch with home while driv-
ing 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,
walkie-talkies are great for communi-
cating 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 assur-
ance it is to be able to radio for assis-
tance.

21-1620.fm Page 21 Thursday, August 5, 1999 11:16 AM
•
Camping, fishing, and other sports
are more fun with a walkie-talkie.
Locate a friend or find out “what’s
cooking” back at camp.

CB 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 PUSH TO TALK
when you are not talking. (This is
called dead keying.)
Assist callers with directions, infor-
mation about road conditions, and
any other reasonable requests.
MAXIMUM RANGE
The maximum range and quality of CB
transmissions vary depending on these
conditions:
•
•
Amount of power in the batteries
The surrounding terrain — moun-
tains and tall buildings limit the range
•
•
Weather conditions
The number of nearby CBs operating
on the same channel
To ensure maximum range, always keep
fresh alkaline batteries or fully charged
nickel-cadmium batteries in your TRC-
235 when using battery power.

ADDING CRYSTALS
Your TRC-235 includes two crystals
(transmit and receive) installed in channel
position A. The crystals let you use the CB
on channel 14. You can add two more
crystals in channel positions B and C so
you can use any two other channels of the
40 allotted to CBs. However, you must
use only crystals specifically designed for
the TRC-235, available from your local
RadioShack store. Be sure to specify the
channel you want and the TRC-235’s cat-
alog number (Cat. No. 21-1620).
Note:
Channel A crystals are soldered in,
and can be replaced only by a qualified
technician.
The following chart shows the frequency
)
pairs (in MHz for receiving and transmit-
ting on each CB channel.

3. Set CHANNEL to A, slide your thumb
under the right edge of CHANNEL,
then carefully pull CHANNEL up to
remove it.
4. Use a Phillips screwdriver to remove
the back cover’s three screws.
Caution: The BATT TEST button
might come off of the front of the
TRC-235 when you remove the front
cover. If this happens, simply replace
it.
5. Firmly grasp the TRC-235’s front and
back cover’s sides and carefully pull
the front cover away from the back
cover.

6. Insert a new matched pair of crystals
(send and receive) into the sockets
for Channel B or C.
The sockets for the crystals are
marked next to Channel A on the cir-
cuit board with X1 (receive) and X2
(transmit). The channel’s letter (A, B,
or C) is marked on the circuit board
and on the diagram below.
Important: Be sure you install the
receive (R) and transmit (T) crystals
in their correct sockets. Do not
reverse the transmit and receive
crystals. If you do, the TRC-235 will
transmit and receive on frequencies
outside the citizen’s band, resulting
in illegal operation.

details left out
for clarity)

7. When you have finished installing
new crystals, carefully fit the TRC-
235’s front cover to the back cover
and gently squeeze them together.
Make sure the BATT TEST indicator
shows through the front of the TRC-
235 when you reassemble it.
8. Replace CHANNEL on the front of the
TRC-235, the back cover’s three
screws, the batteries (if installed)
and the battery compartment cover,
then replace the strap.

MAINTENANCE
Your RadioShack TRC-235 2 Watt 3-
Channel CB Walkie-Talkie is an example
of superior design and craftsmanship. The
following suggestions will help you care
for your TRC-235 so you can enjoy it for
years.
Keep the TRC-235 dry. If it
gets wet, wipe it dry immedi-
ately. Liquids might contain
minerals that can corrode
the electronic circuits.
Handle the TRC-235 gently
and carefully. Dropping it
can damage circuit boards
and cases and can cause
the TRC-235 to work im-
properly.
Use and store the TRC-235
only in normal temperature
environments. Temperature
extremes can shorten the
life of electronic devices,
damage batteries, and dis-
tort or melt plastic parts.
Keep the TRC-235 away
from dust and dirt, which
can cause premature wear
of parts.
Wipe the TRC-235 with a
damp cloth occasionally to
keep it looking new. Do not
use harsh chemicals, clean-
ing solvents, or strong deter-
gents to clean the TRC-235.
Modifying or tampering with the TRC-235’s
internal components can cause a malfunc-
tion and might invalidate your TRC-235’s
warranty and void your FCC authorization
to operate it. If your TRC-235 is not per-
forming as it should, take it to your local
RadioShack store for assistance.
