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 if
he presses his PTT switch. To exit PA mode, push
Mute and
SPR again.
9 Intercom Volume Control
The small volume control knob adjusts the loudness of the
intercom for the pilot and copilot. It has no effect on selected
radio levels, music input levels or passengers' volume level.
The larger, outer volume control knob controls intercom volume
for the passengers. It has no effect on radio or music levels.
10 Intercom Modes
The
ICS pushbutton switch on the left side of the panel provides
the selection of the three intercom modes. (The description of
the intercom mode function is valid only when the unit is not in
the Split mode. Then, the pilot and copilot intercom is
controlled with the
Mute button.)
This button cycles through the intercom modes, from top to
bottom and then back up,
ISO, ALL, Crew, ALL, and ISO. An
LED shows the active mode.
ISO: The pilot is isolated from the intercom and is connected
only to the aircraft radio system. He will hear the aircraft radio
reception (and sidetone during radio transmissions). The copilot
and passengers will hear the music sources as configured by the
audio panel configuration Function keys (Refer to applicable
Pilot’s Guide).
ALL: All parties will hear the aircraft radio and intercom. Crew
will hear Entertainment 1, passengers can hear Entertainment 1
or 2. During any radio or intercom communications, the music
volume automatically decreases. The music volume increases
gradually back to the original level after communications have
been completed.
CREW: Pilot and copilot are connected on one intercom channel
and have exclusive access to the aircraft radios. Again, the
music that the crew and passengers will hear is determined by
the Smart Function Keys (Refer to applicable Pilot’s Guide).
