Music 1 Volume
We recommend adjusting the entertainment volume at the sources, and only
using the audio panel as a master gain control. However, the Music 1 volume
can be adjusted if desired at the front panel by pressing the combinations of
keys listed.
Press Hold Function (TEL) and SPR for more than one second to increase
music 1 volume. This will increase the volume three steps per second.
Press Hold Function (TEL) and Mute for more than one second to decrease
music 1 volume. The music can be turned completely off, so if you aren’t
hearing what you expect, try increasing the volume as described above.
It will take about 12 seconds to go from minimum to maximum volume.
Swap Mode (Switch from Com 1 to Com 2 remotely)
The “swap” button allows you to switch between the COM transmitters
without having to reach up to the audio panel, and is a handy way to switch
to Ground Control when exiting the runway. This optional switch is usually
mounted on the control yoke or a convenient place by the pilot position.
Internal Recorder System
The Intercom Recording System is a continuous loop recorder, (last message
received will be the first heard), the recorder has 60 seconds of recording
time, or up to 16 messages. There are no buttons to press to start recording.
The system automatically begins to record the instant the radio selected for
transmit becomes active. Only the pilot and copilot will hear the playback
audio.
To play back the last recorded message, you press and hold the COM RCV
pushbutton associated with the selected radio transmitter for about one sec-
ond. You must wait for the message to stop playing before accessing the
prior message. To cancel the playback, press and hold the playback button
for two seconds. The next time the button is pressed for one second, the next
earlier message will be heard. If the radio becomes active while a message is
playing, the message playback will stop. The new audio will not be stored.
Press play to restart the message you were playing.
Messages are lost when a different radio is selected for transmit.
The playback will stop whenever there is more incoming selected com audio,
and the message can be replayed from the beginning. Note: an external play-
back button may also be installed in a convenient location.
Public Address Function (if enabled)
To enter PA mode, press both the Mute and SPR buttons at the same time.
The Mute and SPR LEDs will blink to indicate the audio panel is in PA
