IMPORTANT NOTES
Memory Backup
501b
• This unit contains a battery which powers the unit’s
memory circuits while the main power is off. When this
battery becomes weak, the message shown below will
appear in the display. Once you see this message, have the
battery replaced with a fresh one as soon as possible to
avoid the loss of all data in memory. To have the battery
replaced, consult with your retailer, the nearest Roland
Service Center, or an authorized Roland distributor, as
listed on the “Information” page.
Additional Precautions
551
• Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of loosing important data, we recommend that
you periodically save a backup copy of important data
you have stored in the unit’s memory on a USB memory.
552
• Unfortunately, it may be impossible to restore the contents
of data that was stored on a USB memory once it has been
lost. Roland Corporation assumes no liability concerning
such loss of data.
553
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
554
• Never strike or apply strong pressure to the display.
556
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
557
• A small amount of heat will radiate from the unit during
normal operation.
558b
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels (especially when it is late at
night).
559a
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
562
• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this unit.
The use of such cables can cause the sound level to be
extremely low, or impossible to hear. For information on
cable specifications, contact the manufacturer of the cable.
562
• The M-400’s center of gravity is located toward the rear of
the unit. When transporting the M-400, grasp it firmly and
be careful not to let it fall.
562
• If the display becomes extremely dim, it is possible that
the display backlight has malfunctioned. If this occurs,
you must contact your dealer or a Roland service center.
562
• Due to the nature of the display, there may be screen
pixels that remain lit or that fail to light; please be aware
that this is not a malfunction or a defect.
