IMPORTANT NOTES
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 in another MIDI device
(e.g., a sequencer).
552
• Unfortunately, it may be impossible to restore the contents
of data that was stored in the unit's memory or in another
MIDI device (e.g., a sequencer) 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.
558a
• To avoid disturbing your neighbors, try to keep the unit's
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
558c
• Since sound vibrations can be transmitted through floors
and walls to a greater degree than expected, take care not
to allow such sound to become a nuisance to neighbors,
especially at night and when using headphones. Although
the drum pads and pedals are designed so there is a
minimal amount of extraneous sound produced when
they're struck, rubber heads tend to produce louder
sounds compared to mesh heads. You can effectively
reduce much of the unwanted sound from the pads by
switching to mesh heads.
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
• Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the
following precautions.
• 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 infor-
mation on cable specifications, contact the manufac-
turer of the cable.
