The Audio Controller contains 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 has been reached, the recorder begins recording over the stored memory blocks, starting from the oldest block.

After opening the audio panel touch the Playback Button to listen to the latest recorded memory block. The Stop Button and Back Button are displayed while the audio is playing. When the present memory block has finished playing, the Recorder (Playback Button) is displayed again.

Touching the Recorder (Stop Button) during play of a memory block pauses play. If a COM input signal is detected during play of a recorded memory block, play is halted.

Removing power from the system clears all recorded blocks.
