GMA 345 3-COM Audio Panel

TRANSCEIVERS

Audio from the #1, #2, or #3 COM receiver can be selected independently

by pressing the respective Key(s) (COM1, COM2, or COM3). Pressing

COM1 MIC, COM2 MIC, or COM3 MIC selects the #1, #2, or #3 transmitter

and simultaneously selects the related COM receiver (COM1, COM2, or

COM3) allowing received audio to be heard. The other COM receivers can

be added by pressing their respective keys.

By default, while transmitting on a COM channel (as selected with the

COM1 MIC, COM2 MIC, and COM3 MIC keys), both the transmitting and

receiving audio are heard on the COM channel. The GMA 345 3-COM

can be configured to instead mute receiving audio on a transmitting COM

channel. A Garmin authorized service center can make changes to the

default configuration.

Split COM performance is affected by the distance between

NOTE:

the COM antennas and the separation of the tuned frequencies. If the

selected COM frequencies are too close together, interference may be

heard during transmission on the other radio.

During Split-COM operation, both the pilot and the copilot can transmit

simultaneously over separate radios. The pilot uses the lower numbered

COM and the copilot uses the higher numbered COM.

Pressing two MIC Keys simultaneously initiates Split-COM Mode (i.e.,

COM1/COM2, COM1/COM3, or COM2/COM3). The respective COM

receive and MIC annunciators are illuminated indicating Split-COM

operation. Split-COM operation is cancelled by pressing one of the

selected MIC Keys again.

During COM transmission, the active transceiver (COM1 MIC, COM2

MIC, or COM3 MIC) Key Annunciator flashes approximately once per

second.
