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 indicator blinks. The ICS indicator will then blink every few sec-
onds to indicate this mode is active. Music muting will follow the
modes listed above.
Smart Function Keys (SFK) Configuration
Secondary functions give the PMA8000BT some special capabilities.
“Intercom” allows the passengers and crew to converse, in ALL in-
tercom mode, without distracting the crew from radio duties. The pas-
senger microphones are cut out from the crew when the radio is ac-
tive, and the passengers never hear aircraft radios. Press and hold the
TEL button until the audio annunciation starts (about 1 second) to
activate the function, and you will hear “Alternate Intercom Func-
tion.” Hold the button again to exit, and you will hear “Standard Inter-
com Function.”
“Monitor” activates a Monitor Mode. In this case, the audio from
the COM radio that is selected for transmit will mute the other COM
audio when it is active. For example, if COM 1 is selected to transmit
to ATC, but COM 2 is receiving weather information; the ATC will
mute the audio from the weather while ATC is transmitting. In Moni-
tor mode, the RCV COM indicator will blink every few seconds as a
status indication. Monitor mode is set to off when the unit is turned
off.
