radio or intercom., if the Music 1 audio is actively playing.
Music Input
When used as a music input, the front panel jack (and Bluetooth) music are
treated as Music #1. Using the Music function button, it can be distributed to
all users, depending on the intercom mode.
Smart Function Keys (SFK)
With voice feedback, the configuration process is self-directed. These func-

from the crewmember's audio panel.
The volume of the function selection annunciations and recorder playback
can be adjusted through a hole on the top of the unit marked “ANN VOL.”
“Intercom” Function
Function Intercom controls the distribution of aircraft radio and passenger
intercom. In the “Standard intercom function” mode, aircraft radios are dis-

mode, only the pilot and copilot positions will hear aircraft radios.
When in “Alternate Intercom Function,” the passengers will
NEVER hear aircraft radios, even in the ALL mode. In addition,
when in the ALL intercom mode, passengers will be able to con-
verse with the crew, unless the aircraft radio becomes active, when the inter-
com audio from the passengers to the pilot and copilot is stopped, so the
