AUDIO PANEL AND CNS
CLEARANCE RECORDER AND PLAYER
The Audio Panels contain a digital clearance recorder that records up to 2.5 minutes of the selected COM
radio signal. Recorded COM audio is stored in separate memory blocks. Once 2.5 minutes of recording time
have been reached, the recorder begins recording over the stored memory blocks, starting from the oldest
block.
Pressing the
REC Key enables recording of audio from the COM radio selected for transmission. Quiet
periods between COM reception are not recorded.
The PLAY Key controls the play function. The PLAY annunciator indicates when play is in progress. The
PLAY annunciator turns off after playback is finished.
Pressing the PLAY Key once plays the latest recorded memory block and then returns to normal operation.
Pressing the PLAY Key again 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 twice within one-half second while audio is playing plays the previous block of
recorded audio. Each subsequent two presses of the PLAY Key within one-half second will backtrack through
the recorded memory blocks to reach and play any recorded block.
Powering off the unit automatically clears all recorded blocks.
