Viewing the Schedules
The DM-8 can be automated to play back of any of the 99 tracks in the MESSA folder at a pre-set time on selected days
of the week. There are no special limitations on the message mp3 content, so this could be an announcement, sound
effect or even a full music mix.
The schedule must be programmed or edited on a PC as described in the “Preparing the SD Card” section above.
To check that the schedule.txt file has been correctly read by the DM-8, the schedules can be viewed on the LCD
display. To do this, hold down the SCHEDULE/REC button (4) for 5 seconds and use the number 1 (˄) and 5 (˅) buttons
to step through the schedules that are currently active on the DM-8.
These show the time, day(s) and message number that will be triggered at that time.
NOTE: The schedule cannot be edited directly on the DM-8.
Powering Down
To avoid any loud transients through the connected PA system, it is recommended to stop any playback and turn down
the Mic/Line, BGM and OUTPUT level controls as a precaution.
