SPLIT-COM MODE GMA 350 Audio Panel NOTE: Split COM performance is affected by the distance between the COM antennas and the separation of the tuned frequencies.

During Split-COM operation, both the pilot and the copilot can transmit simultaneously over separate radios. Pressing both MIC Keys simultaneously initiates Split-COM Mode (i.e., COM1/COM2). The respective COM1/MIC1 or COM2/MIC2 annunciators are illuminated indicating Split-COM operation. Split-COM operation is cancelled by pressing one of the selected MIC Keys again.
