5.7 DIGITAL CLEARANCE RECORDER
AND PLAYER
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 the latest recorded
memory block, then returns to normal operation.
• Pressing MKR/MUTE while playing a memory block
stops play.
• Pressing the PLAY Key during play begins playing
the previously recorded memory block. Each
subsequent press of the PLAY Key will begin playing
the next previously recorded block.
If a COM input signal is detected while playing, play
is halted and the new COM input signal is recorded as the
latest block.
