The passenger’s intercom also has a SoftMute™ circuit. If the passengers hear the radio, or talk on the in-
tercom, the music will mute. If the audio panel is in CREW mode, then the radio reception will not affect
the passenger music.
Passengers also have a Karaoke Mode. If the passengers are listening to the music 1 input or front panel
input, their Karaoke Mode is controlled by the front panel “Mute” button. If the passengers are listening to
the music 2 input, their Karaoke Mode is activated by an external switch installed either in the panel, or
connected to the AUX button logic output pin on the PMA8000BT.
3.8.1 Music in Pilot ISO mode
If desired, the pilot can elect to hear Music #1, in the ISO mode. While the intercom is in ISO mode, push
and hold the ICS button until the ICS indicator blinks (about 1 second). This mode will be indicated by the
ICS ISO LED blinking slowly (once in every 5 seconds). The pilot will now hear Music #1, and it will mute
in accordance with the Mute mode as described in §3.8.
3.9 Telephone Mode (9)
Warning:
United States FCC Regulations contained in 47 CFR § 22.925 contain prohibition on airborne operation of
cellular telephones. “Cellular telephones installed in or carried aboard airplanes, balloons or any other type
of aircraft must not be operated while such aircraft are airborne (not touching the ground). When any air-
craft leaves the ground, all cellular telephones on board that aircraft must be turned off.”
The TEL mode serves as a full duplex interface for telephone systems such as portable cellular phones with
earpiece jacks (or Bluetooth connectivity (PMA8000BT only). When interfaced with an approved airborne
telecommunications system, the PMA8000BT can serve as a audio control and distribution center. When
TEL is active, the button will blink about twice as fast as the normal transmit rate.
In ALL intercom mode, all crew and passengers will be heard on the phone when they speak. All will hear
selected audio. Com audio is automatically heard in the headsets.
In CREW mode, the pilot and copilot are connected to the telephone. The pilot and copilot will have
transmit capability on the other selected transceiver Com 1 or 2, simply by using their respective PTT
switch.
In ISO intercom mode, when the PMA8000BT is in the TEL mode, the pilot position is in the "Phone
Booth." Only the pilot will hear the telephone, and only he will be heard. He will also have access to Com 1
or 2, and will transmit on that radio using the PTT. All selected audio is provided.
