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 intercom 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.
Some cellular telephones do not provide sidetone (where you hear
yourself speak). You can have the PMA8000BT provide sidetone by
holding both the TEL and ADF buttons at the same time, for more
than one second.
Music Muting
Music source #1 (front panel jack and Music 1 input) has four muting
modes, which are announced in the headset as they are activated.
These are: Radio Mute (aircraft radio mutes music), Intercom Mute
(intercom conversation mutes music), Mute on (both radio and inter-
com 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.
