5.1.4. Playback (Supersedes Record) Operation
• Playback takes precedence over the Recording operation.
• If
either PlayE or PlayL is activated during a recording cycle, the recording immediately ceases with
an EOM marker attached, and without power down, playback of the just-recorded message performs
accordingly. Then device powers down.
