Music in Pilot ISO mode
When the isolate (ISO) mode is activated, the music for the pilot is automatically disabled. If desired, the
pilot can elect to hear music in the ISO mode with a long press or holding the home menu button or the ICS
button, while in the ISO mode.
The pilot can select any music source from the Music distribution menu.
Bluetooth® connection
The PMA450C has a Bluetooth interface. The audio panel is always “discoverable,” so you just need to
search for the PMA450C from your Bluetooth-equipped phone or music source. The default access code is
0000, if needed. Once the PMA450C has been “paired” with your Bluetooth device, the TEL distribution
will act as described in §
When Bluetooth is active, a Bluetooth icon and the battery status of the device is displayed in the upper right
corner of the home display.
3.10.1 Pairing and un-pairing Bluetooth devices
The PMA450C BT1 Module can be paired with up to eight individual devices. When that number is ex-
ceeded, the PMA450C will drop a device to allow the new device to be added.
If the audio panel is turned on before the Bluetooth device, you will have to connect manually from your
Bluetooth device. Otherwise, the audio panel should connect automatically.
