6.1.4 Playback (Supersedes Record) Operation
24
• Playback takes precedence over the Recording operation.
• If either ¯P¯la¯y¯E¯ or ¯P¯la¯y¯L¯ 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.
