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.

●
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.
