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

Turning On The CB and Receiving Transmissions

1.  Turn SQUELCH fully counterclockwise.

2.  To turn on the CB, turn VOLUME clockwise until it clicks and you hear
    a hissing sound.  The CB displays the last selected channel.

3.  To tune to a specific channel, rotate CHANNEL clockwise or
    counterclockwise until the display shows the desired channel.

    To rapidly move up or down the channels, turn CHANNEL only slightly 
    to the left or right.

4.  Slowly turn SQUELCH clockwise until the hissing sound stops.

    Note:  If the CB picks up unwanted, partial, or very weak 
           transmissions, turn SQUELCH clockwise to decrease the CB's
           sensitivity to these signals.  Turn SQUELCH counterclockwise if
           you want to listen to a weak or distant station.
 
5.  Adjust VOLUME to a comfortable listening level.

6.  To turn off the CB, turn VOLUME counterclockwise until it clicks.

Transmitting

Note:  We recommend you try receiving before you transmit.

1.  Follow Steps 1 - 5 in "Turning On the CB and Receiving Transmissions"
    above.

2.  Hold down PUSH TO TALK and speak into the microphone in a normal voice
    from about 2 - 3 inches away.  The orange TX indicator lights.

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

3.  When you finish transmitting, release PUSH TO TALK.  The TX indicator
    turns off.  The TRC-442 can now receive transmissions.

4.  To turn off the CB, turn VOLUME counterclockwise until it clicks.

CB Operation Tips

Like most activities, CB radio has its customs and courtesies. The 
following tips will help you get the most enjoyment from your CB.

Common Uses For a CB Radio

Business Uses

   Truck drivers and delivery personnel can learn road and traffic
   conditions and get 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.

   For security officers, a CB is more than a convenience - 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.

   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.

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 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.

Maximum Range

The maximum range and quality of CB radio transmissions vary depending on
these 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 the range

   Weather conditions

   The number of nearby CBs 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.
