Intercom Modes

The "ICS" pushbutton switch on the panel provides the selection of the
intercom modes
The intercom mode defaults to "CRW" at power up. Then the button cycles
through the intercom modes, from bottom to top, then top to bottom: PAX
CRW ISO, CRW. A green indicator shows which mode is currently active.
Iso: Each control head has their own ISOLATE selection. The control head
is isolated from the intercom stations and is connected only to the aircraft
radio's that are selected system. They will hear the aircraft radio reception
(and sidetone during radio transmissions).
Crw: Pilot and copilot are connected on one intercom channel and have
exclusive access to the aircraft radios. The pilot or copilot control head will
decide when the system will be in the ALL mode by pressing their ICS
switch. The observers can communicate with each other and passengers in
ALL or OBS mode or select ISO mode.
Pax: Pilot and copilot have the option to add passengers to their intercom
channel by holding down the ICS button for 4 seconds. This will then all
passengers to speak with that crew station. Cycling power will place system
back into the Crew mode and no passengers.
Remote ICS Mode Control
An optional external switch can act as a remote intercom mode selector.
Pressing the switch will increment the intercom mode selector from ISO--
CRW-ISO-PAX, etc. each time the button is pressed.
Bluetooth® connection
The PAC45L has an internal Bluetooth module, no external boxes required.
The audio controller is always "discoverable," so you just need to search
for the PAC45L from your Bluetooth-equipped phone or music source.
Default access code is not required. Once the PAC45L has been "paired"
with your Bluetooth device, the TEL distribution will act as described be-
low.
Pairing Bluetooth® devices
The PAC45L can be paired with up to eight individual devices, but will
only connect to one at a time. When that number is exceeded, the PAC45L
will drop a device to allow the new device to be added.
If the audio controller is turned on before the Bluetooth device, you will
have to manually connect from your Bluetooth device. Otherwise once
paired, the audio controller should connect automatically.
