CLEARANCE RECORDER AND PLAYER
The GMA 350/350c 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
have been reached, the recorder begins recording over the stored memory
blocks, starting from the oldest block.
