GMA 245 Audio Panel

Note that the GMA USB dust cover can be clipped to any USB cable

plugged into the GMA. The dust cover has a clip feature that can attach to a
USB cable for temporary storage to prevent losing the cover.

FAIL-SAFE OPERATION

If there is a failure of the GMA 245 or when power is not applied, a

fail-safe circuit connects the pilot’s headset and microphone directly to the
COM1 transceiver. Audio is not available on the speaker during Fail-safe
operation.
