Using The TRC-517

1.  To turn on the TRC-517, slide VOX/PTT/OFF to either VOX or PTT.

2.  Set the TRC-517 to the desired channel (A through E).

    Notes:  With the TRC-517, you can communicate with an unlimited number 
            of walkie-talkies that are on the same channel.

            To talk privately to specific people, you and the other 
            person(s) in the conversation must switch to another specified 
            channel.

            Your TRC-517 cannot receive while transmitting.  Wait for the 
            other person to stop talking before you transmit.

3.  For handsfree (voice-activated) operation, make sure the volume is set
    to L.  Slide VOX/PTT/OFF to VOX, then set VOX/MIC for the best
    transmission and reception sensitivity as follows:

      In a noisy environment, set VOX/MIC to L (low).  This prevents the 
      TRC-517 from continuing to transmit after you speak due to 
      background noise.  With this setting, you must speak into the 
      microphone louder to transmit.

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

    To transmit manually, slide VOX/PTT/OFF to PTT.  Press PUSH TO TALK to 
    transmit, and release it to receive.

4.  Set VOLUME to the desired listening level (H for high volume, M for
    medium volume, or L for low volume).

5.  To turn the TRC-517 off when you are finished, slide VOX/PTT/OFF to
    OFF.

Using The Audio Input Jack

You can attach an audio cassette or radio to the TRC-517 so you can listen 
to music while talking to others.

Simply plug one end of the supplied 1/8-inch (3.5-mm) audio input cable to 
the audio input jack on the TRC-517's plug, and the other end to the 
headphone jack on the audio source.
