TRC-507  (210-0407)             Operation              Faxback Doc. # 3565

Follow these steps to operate the transceiver.

1.  Straighten the whip antenna.

    NOTE:  The range is greatly reduced when the antenna remains clipped;
           but, if the antenna restricts your movement, tighten it to the
           headband.

2.  Put on your headset.  Adjust it for a comfortable fit.  Put the
    microphone within 1 inch of your mouth.

3.  Set POWER to VOX (for hands-free communication) or MAN (for manual
    push-to-talk operation).

4.  Switch the channel selector to the communication channel you want to
    use (A through E).  All other transceivers that you want to
    communicate with must be on the same channel.

5.  Set VOLUME for the most comfortable listening level.

6.  If you selected VOX operation, set VOX/MIC for best operation as
    follows:

    In a noisy environment, set VOX/MIC to L (low).  This prevents back-
    ground noise from keeping the transceiver in the transmit mode.

    With this setting, you must speak louder into the microphone to make
    the transceiver transmit.

    In a quieter area, set VOX/MIC to M (medium) or H (high).  At these
    settings, you do not have to speak as loudly to switch to transmit.

While you transmit, you hear your voice through the earphone.  If you
cannot hear your voice, you are talking to softly--speak a little louder
or set VOX/MIC to H or M.  But, shouting into the microphone does not
increase the signal strength; it only increases distortion.

If you selected manual operation, press PUSH TO TALK to transmit.  Release
PUSH TO TALK to receive.

The TRC-507 cannot receive while transmitting.  Wait for the other person
to stop talking before you transmit.

FCC NOTICE

Your transceiver might cause TV or radio interference even when it is
operating properly.  To determine whether your transceiver is causing the
interference, turn off your transceiver.  If the interference goes away,
your transceiver is causing the interference.  Try to eliminate it by:

    Moving your transceiver away form the receiver.

    Contacting your local Radio Shack store for help.

If you cannot eliminate the interference, the FCC requires that you stop
using your transceiver.
