This pilots guide provides operating instructions for the KMA 30 Audio
Panel. Please read it carefully before using the equipment so that you can
take full advantage of its capabilities.
This guide is divided into operating sections such as Transceiver Selection,
Audio Selector, Intercom, and Marker Beacon Receiver, and special func-
tions. The center section provides a handy reference that you can remove.
Power Switch (1) (EMG-Fail Safe Operation)
The power switch controls all audio selector panel functions, intercom and

When the unit is turned off, either by pressing the volume control, or if the
breaker is pulled removing power, the KMA 30 is in Fail-Safe mode. In this
mode, the pilot's headset is connected to COM 1 for transmit and receive,
and connected to unswitched input #1 for priority audio alerts. The fail safe
audio will only be heard in the left ear of a stereo headset.
