TRC-464  (210-1554)            Operation              Faxback Doc. # 6311

Before you start using the CB, you should know how to use it effectively
and courteously.  "CB Operation Tips" contains information that will help
you get more enjoyment from the CB.

RECEIVING TRANSMISSIONS

Caution:  Do not attempt to use the CB if you have not connected it to an
          antenna.

1.  Turn SQUELCH fully counterclockwise.

2.  Turn VOLUME clockwise.  You hear a click, and the green RX indicator
    lights to indicate that the CB is ready to receive transmissions.

3.  Adjust VOLUME to a comfortable listening level.

4.  Turn CHANNEL DOWN/UP to select the desired channel.  The channel
    number appears on the display.

To move through the channels one at a time, turn and quickly release
CHANNEL DOWN/UP for each channel you want to hear.  To move through the
channels quickly, turn and hold CHANNEL DOWN/UP.

5.  Adjust SQUELCH to cut out background noise.

Note:  To receive a weak transmission, turn SQUELCH counterclockwise.

6.  To turn off the TRC-464, turn VOLUME counterclockwise until you hear
    it click.

TRANSMITTING

1.  Set up the CB's controls as described in "Receiving Transmissions"

2.  Hold the microphone 2 or 3 inches from your mouth.  Press and hold
    down the microphone talk button and speak into the microphone in a
    normal voice.  The red TX indicator lights.

Note:  Do not speak too loudly when transmitting.  It does not make
       your signal any stronger, and might distort your transmission.

3.  When you finish transmitting, release the microphone talk button.
    The green RX indicator lights.  You can now receive transmissions.

4.  To turn off the TRC-464, turn VOLUME counterclockwise until you hear
    it click.

CB OPERATION TIPS

Like any other activity, CB radio has its rules and courtesies.  The
following tips will help you get the most enjoyment out of your CB.

COMMON USES FOR A CB RADIO

Business Uses:

For security officers, a 2-way radio 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 obtain assistance in locating destinations.  A CB is
also good company on those "long hauls."

On construction crews, a CB quickly pays for itself when you are calling
for additional materials or coordinating the activities of different work
crews.

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, CBs 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.  You can even meet new friends this way.

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, or other sports are more fun with a CB.  Locate a
buddy or find out "what's cooking" back at camp.

CB COURTESY

Follow these courtesy guidelines when using the CB.

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 microphone 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.

USING CHANNEL 9

Channel 9 is reserved for reporting emergency information about
accidents, hazardous road conditions, and so on.  Do not use Channel 9
for non-emergency messages.

MAXIMUM RANGE

The maximum range and quality of CB 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 reception.

The surrounding terrain - mountains and tall buildings limit the range.

Weather conditions.

The number of nearby CBs operating on the same channel.

Standing wave ratio (SWR) between the antenna and the CB.  You can set
the SWR by using an SWR tester (such as Radio Shack Cat. No. 21-523).
Follow the instructions that come with the SWR tester.

USING COMMON 10-CODES

Citizen's band operators have largely adopted the 10 codes for standard
questions and answers.  These codes permit faster communication and
better intelligibility in noisy areas.  The following table lists some of
the more common codes and their meanings.

Code                                       Meaning
10-1                              Receiving poorly
10-2                                Receiving well
10-3                             Stop transmitting
10-4                                            OK
10-6                                     I am busy
10-7                                Out of service
10-8                                    In service
10-9                                        Repeat
10-10                            No or standing by
10-13               Advise road/weather conditions
10-20                       What is your location?
10-33                            Emergency traffic
10-36                             What time is it?
10-41                            Switch to channel
10-62                            Cannot understand
