decreases. The music volume increases gradually back to the original level
after communications have been completed.
Crew (CRW): Pilot and copilot are connected on one intercom channel and
have exclusive access to the aircraft radios. The observer and passengers will
be able to talk to each other.
In addition, the following rules apply:
•
System defaults to ALL-ALL-ALL at power up.
•
Any panel can select ISO, and be removed from the intercom.
•
Either pilot or copilot panel can select CRW, and place both panels in
Crew mode, while the observer audio controller is forced to ISO.
•
Either pilot or copilot panel can select ALL and add everybody to the in-
tercom.
•
The Mission Observer panel can select ISO, and then select ALL, unless a
pilot or copilot has selected ISO or CREW.
With the CTL45M installed, the observer/mission personnel
isolate their audio feed from the crew by pressing the ICS
button. When the CTL45M is in ISO mode, the observer/
passengers will have intercom among themselves, and be
able to use the selected radios.
If the flight crew selects ISO or Crew modes, the CTL45M
will automatically enter the ISO mode, and will not change
modes unless the crew changes their state. If the observer personnel desire to
communicate with the crew, pressing "CALL" will activate an ICS call light
and a chime in the crew headsets.
Remote ICS Mode Control
An optional external switch can act as a remote intercom mode selector. Press-
ing the switch will increment the intercom mode selector from ISO-ALL-
CRW-ISO-ALL, etc. each time the button is pressed.
Bluetooth® connection
The PAC45 has an internal Bluetooth module, no external boxes required. The
audio controller is always "discoverable," so you just need to search for the
PAC45 from your Bluetooth-equipped phone or music source. Default access
code is not required. Once the PAC45 has been "paired" with your Bluetooth
device, the TEL distribution will act as described below.
Pairing Bluetooth® devices
The PAC45 can be paired with up to eight individual devices, but will only
connect to one at a time. When that number is exceeded, the PAC45 will drop
a device to allow the new device to be added.
