UPGRADES AND SERVICE
SYSTEVISOFTVWARE
Roland will periodically release new versions of system software to fix
problems or add new features. When software upgrade ROMs are
available, you will need to bring your unit to a Roland Authorized
Service Center for installation.
A DM-80-4 can be upgraded to eight tracks with the installation of the
DM-80-E Expansion Upgrade. The DM-80-E must be installed by a
Roland Authorized Service Center. For more information, contact
Roland or your nearest Roland Authorized Service Center.
IF THE
DM-80
DOESN'T FUNCTION
Before you take your unit for servicing, check and be sure one of the
following situations is not causing your problem.
e
Check that all cables are connected properly. -
¢
Make DM BUSS, SCSI, MIDI and Serial (RS-422) connections with
the power off.
¢
Make sure all disks in the same group are connected, and that all
disks are connected to the proper SCSI connector.
e¢
Never disconnect any cable while the system is on. If this occurs
you will be forced to turn off the power to the system, and all
unsaved data will be lost.
¢
Did you power up the system in the proper order? See page 17.
