5.7 DIGITAL CLEARANCE RECORDER
AND PLAYBACK
Each reception of primary active COM audio is
automatically recorded in a memory block. When the next
transmission is received, it is recorded in the next memory
block, and so on. Once the 2.5 minutes of recording time
has been reached, the recorder begins recording over the
stored memory blocks, starting from the oldest block.
Powering off the unit automatically clears all recorded
blocks.
Figure 5-9 Playback
• Pressing PLAY once plays back the latest recorded
memory block, then returns to normal operation.
• Pressing PLAY during playback of a memory block
halts the playback of this block and plays back the
preceding recorded block. The PLAY Key can be
used to backtrack through the recorded memory
blocks to reach and play back any desired block.
• Pressing the MKR/MUTE Key during playback
halts playback and returns the recorder/playback
to normal operation.
If a COM input signal is detected during playback,
playback is halted and the new COM input signal is
recorded as the latest block.
