“Smart” Front Panel Jack
When music 1 is actively playing through the rear panel input, the
front jack automatically becomes an advisory audio input, and is NOT
muted by radio or intercom conversations. This is useful for connect-
ing portable traffic or terrain alert devices. If Music 1 is not active, the
mute mode should be deselected.
Recorder Playback
The internal recorder is always storing the audio from the radio se-
lected for transmit. To play back the last incoming audio, hold the
RCV (top) button on the radio selected
to transmit for one second, and release.
The playback will start. Playback stops
if the radio becomes active, but the new
incoming message will not be recorded.
When the radio stops, press play and you
will be in the same message you had
playing.
To hear an earlier message, hold the COM RCV button until playback
stops again, and then press again to begin playing the next earlier
message. Repeat until you hear the message you wanted. Incoming
new messages will stop playback, and you can then restart.
A remote playback switch may also be installed.
Note: when you switch from one transmitter to another, the recordings
are lost.
