the COM radio that is selected for transmit will mute the other COM
audio when it is active. Fro example, if COM 1 is selected to transmit
to ATC, but COM 2 is receiving weather information; the ATC will
mute the audio from the weather while ATC is transmitting. In Moni-
tor mode, the RCV COM indicator will blink every few seconds as a
status indication. Monitor mode is set to off when the unit is turned
off.
Function C controls music distribution, and has three states; Stan-
dard Music Distribution, Alternate Music Distribution and Music
1 All Headsets.
Music 1 (the MP3 player or the Music 1 input on the rear connector)
can be distributed to all headsets regardless of intercom mode.
In Standard Music Distribution, Music 1 is provided to the crew, and
Music 2 is independently provided to the passengers.
In Alternate Music Distribution, Music 1 is provided to everybody in
the ALL intercom mode, and Music 2 becomes active, for the passen-
gers only, when the intercom is in the CREW mode.
“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 the music 1 is NOT ac-
tive, the Music mute should be deselected.
Recorder Playback
The internal recorder is always storing the audio from the radio se-
lected for transmit. To playback the last incoming audio, hold the
RCV button for 1 second, and release. Playback of most recent mes-
sage will start. To hear an earlier message, hold the COM RCV button
until playback stops again, and then press again to begin playing the
