MESSAGE CUEING
Message cueing allows the user to skip through messages, without having to know the actual physical
location of each message. This operation is used during playback. In this mode, the messages are
skipped 512 times faster than in normal playback mode. This operation will stop when an EOM marker
is reached. Then, the internal address counter will be pointing to the next message.
ANALOG MODE

(See
