BTX-123 Business Band Transceiver

RECEIVING TRANSMISSIONS AND ADJUSTING SQUELCH

Note:  Make sure the transceiver's antenna is connected before you turn it
       on.

1.  Turn SQUELCH fully counterclockwise.

2.  Turn on the transceiver by turning VOLUME clockwise until you hear a
    click and a hissing sound.

3.  Turn SQUELCH clockwise until the hissing sound stops.

Notes:

   The BUSY/TX/BATT indicator on the front of the transceiver lights green
   when the transceiver receives a transmission.

   If the transceiver picks up unwanted, partial, or very weak 
   transmissions, turn SQUELCH clockwise to decrease the transceiver's
   sensitivity to these signals.  If you want to listen to a weak or distant
   station, turn SQUELCH counterclockwise.

4.  Set CHANNEL to A or B.

    Note:  Your transceiver comes with crystals installed in channel
           Position A.  To use other frequencies, you must first install
           crystals in channel position B inside the transceiver.

5.  If you are using the supplied antenna, hold the transceiver so the
    antenna is vertical.

6.  Adjust VOLUME to a comfortable listening level.

7.  To conserve battery power, set RF POWER to LO.  Or, if the person you
    are transmitting to has trouble receiving your signal, set RF POWER to
    HI.

8.  To turn off the transceiver, turn VOLUME toward OFF until it clicks.

TRANSMITTING

1.  Follow steps 1-7 in "Receiving Transmissions and Adjusting Squelch."

2.  Hold the transceiver 2-3 inches from your mouth.  Hold down PUSH TO
    TALK and speak into the microphone on the front of the transceiver in a
    normal voice.

    The BUSY/TX/BATT indicator on the front of the transceiver lights red
    when you press PUSH TO TALK.

3.  When you finish speaking, release the button.

4.  To turn off the transceiver, turn VOLUME toward OFF until it clicks.

    Notes:

    The transceiver's automatic modulation circuit adjusts the microphone's
    sensitivity for a wide variety of voice levels.

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

    Do not hold down PUSH TO TALK when you are not talking.  (This is called
    dead keying.)

OPERATIONAL HINTS

Your transceiver's range varies depending on factors such as position,
terrain, and battery condition.  Buildings absorb transmitted signals and,
if they contain metal, might completely block them.  Trees and heavy cloud
formations have a similar effect, though not as severe.  If you are near a
lake or the ocean, you might get excellent range.

To ensure maximum range, operate the transceiver with the battery pack 
fully charged.  As the voltage decreases, the range decreases.
