volume (rear input only) can be adjusted from the front panel,
if desired, by pressing SPR button.
NOTE: Increasing this music level can increase the amount of
aircraft electrical system noise as well.
Press the Music Volume (SPR) for more than one second, a tone will be
heard indicating the volume level is changing and the music volume will
begin to change. The volume will either increase or decrease, depending on

Note: Since it is possible to turn the volume completely off, you may need to
turn the volume up if you don’t hear music when you expected to.
It will take about 10 seconds to go from minimum to maximum volume.
Swap Mode (Switch from COM 1 to COM 2 or COM 3 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.
COM 3 can be included in the SWAP rotation if desired. Hold the external
swap button and the COM 3 XMT at the same time to add or remove COM 3
from the Swap function.
Internal Recorder System
The Internal Recording System is a continuous loop recorder, (last message received
will be the first heard), the recorder has 45 seconds of recording time, or up to eight
messages. The system automatically begins to record the instant the radio selected for
transmit becomes active. Only the crewmember will hear the playback audio from
their audio panel.
To play back the last recorded message, you press and hold the COM RCV pushbut-
ton associated with the selected radio transmitter for about one second. 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 play-
ing, 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, or
when power is removed from the audio panel.
The playback will stop whenever there is more incoming selected com audio, and the
message can be replayed from the beginning. Note: an external playback button may
also be installed in a convenient location.
