3.11 Smart Function Keys (SFK)
With Virtual Tech Support, the configuration process is self-directed. SFK annunciations are heard by the
pilot and copilot positions only. SFK annunciations will be heard by the copilot, even when the audio panel
is in pilot isolate mode. These annunciations will be stopped by any audio received on the com radio select-
ed for transmitting.

These functions are non-essential and non-required and as such are only an accessory capability.
They don’t affect the audio panel’s primary function as a selector panel, aircraft intercom, or
marker beacon receiver. You can’t do anything with these buttons to prevent the PMA8000D from
doing its main job.
Looking at the front panel you’ll notice that the COM 3, AUX, Mute and SPR buttons have “Function” as-
signments.
To use these function keys A, B, C – press and hold the desired key, “Intercom” (COM 3) “Monitor”
(AUX) “Music” (Mute) and “Music Volume” (SPR).
