RECEIVERS

NAV RECEIVER

Pressing the NAV1 and/or NAV2 Key(s) selects/deselects the receiver audio
for the corresponding navigation radio source. The selected audio source
can be heard over the headset and the speaker (if selected). All radios can
be selected individually or simultaneously.

AUXILIARY INPUTS

The GMA 345 3-COM has 3 AUX inputs. A single AUX Key selects all
three AUX inputs to be simultaneously heard.

MARKER BEACON RECEIVER

The marker beacon receiver detects any marker beacon signal within
the reception range of the aircraft.
When a marker beacon signal is detected, the lamps illuminate, and
an associated keyed-tone is heard when MKR audio is selected. Marker
beacon lamps operate independently of any audio selection and cannot
be turned off.
