modeon the intercom to facilitate the call. The pilot will still have complete

The copilot panel’s Bluetooth transceiver will provide music and telephone
for the copilot and the passengers.
The copilot’s Bluetooth device connects the copilot, pilot and passengers to
this phone and music source. This connects the telephone to the users as fol-

*Passenger exclusive telephone conversation.
In cases where the copilot’s cellular telephone doesn’t provide sidetone, the
audio panel can be configured, by holding the COM 3 and ADF buttons for

for more than 32 seconds. When a stuck mic is detected, the key input is
ignored, and the other crewmember can transmit normally. If the stuck be-
comes ungrounded, normal operation is restored.

functions, Advisory audio input and Music input (wired)
Audio Advisory Input
The front jack can be used as a priority advisory input for auxiliary systems
such as a GPS terrain advisory or portable traffic watch system. To prevent
radio or intercom from muting this input, press the “Mute” button to until
“Mute Off” is heard.
NOTE: The front jack is no substitute for the certified installation of alerts
such as the GPS waypoint or autopilot tones. These still must be hard wired
into the back by your installer.
“Smart Jack” Function
When the PMA8000D has an audio signal on music #1 from the rear connec-
tor, the front panel jack automatically becomes a Priority Advisory input,
