This mode is useful if your passengers have a different interest in
entertainment or are watching a DVD, but do not want to be ex-
cluded from the intercom conversations.
Public Address Function (if enabled)
To access PA function, press the Mute and SPR buttons simultane-
ously. The Mute and SPR LEDs will blink to indicate the audio
panel is in PA mode. The copilot can continue to use the selected
com radio while the pilot will now be heard over the speaker. To exit
PA mode, push Mute and SPR again. PA mode is not remembered
through power cycles.
Internal Recorder System
The Intercom Recording System is a digital recording system allow-
ing automatic storage and playback of aircraft radio traffic.
Operating as a continuous loop recorder, (first message received will
be the last heard), the recorder has 52 seconds of recording time, or
up to 8 messages. With its own built in
VOX circuit, there are no buttons to
press to start recording. The system
automatically begins to record the in-
stant the radio becomes active. Only the
com radio selected for transmit is re-
corded, and only the pilot and copilot
will hear the playback audio. If the radio
becomes active during playback, the playback will stop, and it will
not record this communication.
Playback
Recording is automatic. To play back the last recorded message,
press and hold the Com Receive pushbutton associated with the se-
lected radio transmitter for about one (1) second. You can either wait
for the message to finish playing before accessing the prior message,
or cancel the playback. To cancel the playback, press and hold the
playback button for two seconds. The next time the button is pressed
for one (1) second, the next earlier message will be heard.
The playback will stop whenever there is more incoming selected
com audio, and the message can be replayed from the beginning by
pressing the Com receive button again.
