Smart Function Keys (SFK) Configuration
These secondary functions give the PMA8000C some special capa-
bilities. 
“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 
COM 3 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. 
“Music” controls music distribution, and has three states; Standard 
Music Distribution, Alternate Music Distribution and Music 1 All 
Headsets. 
Music 1 (the Bluetooth device or the Music 1 input on the rear con-
nector) can be distributed to all headsets depending on intercom 
mode. 
In Standard Music Distribution, Music 1 is provided to the crew, and 
Music 2 is independently provided to the passengers.
