AUDIO PANEL AND CNS
SPLIT COM
NOTE:
Split COM performance is affected by the distance between 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 can still monitor NAV1, NAV2, AUX, and MKR Audio as selected, but the copilot is only able to
monitor the higher numbered COM (COM2 or COM3).
Selection of more than one
MIC
Key selects Split COM operation (using COM1/COM2, COM1/COM3, or
COM2/COM3). The COM1/MIC1, COM2/MIC2, or COM3/MIC3 annunciators are illuminated indicating
Split COM operation. The selected COM frequencies are displayed in green indicating that both transceivers
are active. Split COM operation is cancelled by pressing one of the selected
MIC
Keys again.
When in Split-COM mode, the pilot is using the lower numbered COM, the copilot is using the higher
numbered COM. The MIC1 or MIC2 (depends on COMs selected for Split-COM) Annunciator flashes when
the pilot’s microphone PTT is pressed. The MIC2 or MIC3 (depends on COMs selected for Split-COM)
Annunciator flashes when the copilot’s microphone PTT is pressed.
