Telephone Operation
When the TEL button is active, the cellular telephone is added to the
intercom loop, and who is connected to the phone depends on the in-
tercom mode.
You can answer a call by pushing the TEL button
while it is ringing. Calls can be answered from the
telephone handset or the audio panel. You can dis-
connect from either the handset or the audio panel.
When a call is disconnected or dropped, the TEL
button indicator will extinguish after a few moments.
Music Muting
Music source #1 (front panel jack and Music 1 input) has three muting
modes, which are announced in the headset as they are activated.
These are: Radio Mute (aircraft radio mutes music), Mute on (radio
and intercom mutes music), and Mute off (nothing interrupts music).
Press the Mute button to cycle through the modes in sequence.
Music #2 has muting on or off, and is externally controlled.
Music in pilot isolate mode
The pilot can elect to listen to Music 1, even in the Pilot Isolate mode.
While already in the ISO mode, press and hold the ISO button until
the
in-
dicator blinks. The ICS indicator will then blink every few seconds to
indicate this mode is active. Music muting will follow the modes
listed above.
