AUDIO PANEL AND CNS
CLEARANCE RECORDER AND PLAYER
The Audio Panel contains a digital clearance recorder that plays up to 2.5 minutes of COM signal recording
from the selected COM radio. Recorded COM audio is stored in separate memory blocks. Once the 2.5
minutes of recording time have been reached, the recorder begins recording over the stored memory blocks,
starting from the oldest block.
The PLAY Key controls the play function. The PLAY Annunciator flashes, indicating when play is in progress.
The PLAY Annunciator turns off after the present memory block has finished playing.
Pressing the PLAY Key once plays the latest recorded memory block and then returns to normal operation.
Pressing the MKR/MUTE Key during play of a memory block stops play. If a COM input signal is detected
during play of a recorded memory block, play is halted.
Pressing the PLAY Key while audio is playing begins playing the previously recorded memory block. Each
subsequent press of the PLAY Key selects the previously recorded memory block.
Powering off the unit automatically clears all recorded blocks.

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, 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.
