MESSAGE
General:
Messages are audio signals, stored in the DMM 4650 as information, alarm announcements or other often
used texts. Recording a message can be performed directly at the DMM 4650 or by means of remote
recording. Playback via sum output is achieved by starting a message (Mxx) within a suitable sequence
(see “Trigger”, “Sequence”).
For test purposes the message can be listened to via the Pre-listen outputs using the recorder keys
PLAY/STOP. The functions are similar to a cassette recorder, with the difference that the audio data is
saved digitally in maintenance-free flash memories. Depending on individual needs, different audio
qualities are selectable. The maximum recording time depends on the selected audio quality and the
installed memory (see table, page 14).
A backup of all message audio data is possible through analog recording (cassette deck, DAT recorder)
or as a digital backup on a computer via the remote interface (RS 232).
Message number, Preset
Up to 100 distinct messages (M00 to M99) including title, name, and priority can be saved.
The DMM 4650 is shipped without any pre-recorded messages, since - depending on individual user
requirements and custom applications – variations would be numerous. Some factory preset sequences
use M00, M01, and M02 (see list of preset sequences). Thus, they have to be recorded for incorporating
them in the respective applications. Some text examples are to be found at the end of this manual.
Operation menu “message”
Confirming the menu selection “message” by using the soft key “ok”, the number of the message appears
in the display together with its title and playback time (hours : minutes . seconds). The DMM 4650 is now
in the recording/playback mode and can be operated using the transport-keys as follows:
Note: This mode only allows playback via the PRE-listen/Phone outputs!
Title skip backwards, selects the previous actually recorded message. During playback
the selected message starts playing immediately.
Rewind, skips back one message, during playback fast rewind enables the user to listen
to a specific part several times.
Play/Stop starts or stops the playback of the selected message. Recording is stopped by
pressing the stop key.
Recording, pressing this key once switches the selected message into recording stand-by.
In case a previously recorded message exists, the question “delete?” is displayed and
leaving you the choice to record a new message with “Y=Yes” or cancel the command
with“N=No”. If you choose delete, the record key has to be pressed again after completion
of the procedure. If this message is not supposed to be deleted, you have to select an empty
location. The items “Recording type ”and “Recording level” are explained later. The display
now shows “record Mxx” and “pause” with a bargraph, indicating the current signal level.
Pressing the record key again starts the recording and “play time” replaces “pause”.
Pressing the Stop/Play-key terminates the recording.
Fast forward, skips to the next message, forwarding during playback enables the user to
listen to parts of a longer message.
Title skip forward, selects the next actually recorded message, during playback this next
message is immediately audible.
Using the cursor keys lets you select the previous or next message number.
Soft key “vl” accesses the volume setting dialog for the phone and pre-listen outputs using
the cursor keys.
Soft key “edt” accesses the menu level for title editing, etc. (see following paragraph).
