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 COM1 and COM2 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, ADF, DME, and MKR Audio as selected, but the copilot is only able
to monitor COM2.
Pressing the COM 1/2 Key selects Split COM operation. The COM 1/2 Annunciator is illuminated indicating
Split COM operation. Split COM operation is cancelled by pressing the COM 1/2 Key again, at which time the
annunciator is extinguished.
When Split COM operation is selected, COM1 is used by the pilot and COM2 is used by the copilot. The
COM1 MIC Annunciator flashes when the pilot’s microphone PTT is pressed. The COM2 MIC Annunciator
flashes when the copilot’s microphone PTT is pressed.
