ENABLED KEYED
ICS
When set to ON, the intercom system (ICS) will only allow intercom
MIC audio to be heard when the corresponding ICS KEY for the MIC
position is pressed. When set to ON, auto squelch will NOT be active.

PILOT IN RIGHT
SEAT
This setting is for intercom 3D audio. Normally the Pilot will be
positioned to the left in the Copilot’s headset, and the Copilot will be
positioned to the right in the Pilot’s headset. When set to ON, this
setting reverses that so the Pilot is positioned to the right in the
Copilot’s headset, and the Copilot is positioned to the left in the Pilot’s
headset.
For the GMA 345 3-COM unit, this also sets which knobs control Pilot
volumes vs. Copilot/Passenger volumes.

MUTE ON COM

When set to ON, the monitored COM radio is muted during mic-
selected COM transmission (mic-selected COM is still heard, but not
the monitored COM radio).

Bluetooth transceiver on GMA 345, or 1, 2, Jack on GMA 342),
regardless of what state of the MUSIC button is set to (ON or OFF), the
passengers will always get MUSIC 2.
