Pressing the CREW ‘ICS ISOLATION’ Key places the pilot and copilot
on a common ICS communication channel. The passengers are on their
own intercom channel and can communicate with each other, but
cannot communicate with the pilot and copilot. A solid annunciation
of the inkey annunciator indicates CREW ICS ISOLATION is active.
INTERCOM VOLUME
The knobs on either side of the GMA 345 3-COM control intercom and
music volume independently. The left inner and outer knobs control the
audio levels for the left seat crew member headset; the right inner and
outer knobs control audio levels for the right seat crew member headset.
Passenger volumes are shared with the side configured for copilot
operation. The inner, smaller knobs on both sides are used to control
intercom volume for the receiving headsets. The outer, larger knobs are
used to control music volume.
The left inner knob can be used to turn off the GMA 345 3-COM
audio panel, by turning fully counter-clockwise until the knob clicks. All
backlight and annunciator LEDs will turn off.
The position marks on all four knobs are not night-time visible.

channel 1, music channel 2 and Bluetooth music audio when radio (i.e.,
COM, NAV, or AUX) audio is active.
