IMPORTANT NOTES
Power Supply
301
• Do not connect this unit to same electrical outlet that is being
used by an electrical appliance that is controlled by an
inverter (such as a refrigerator, washing machine, microwave
oven, or air conditioner), or that contains a motor. Depending
on the way in which the electrical appliance is used, power
supply noise may cause this unit to malfunction or may
produce audible noise. If it is not practical to use a separate
electrical outlet, connect a power supply noise filter between
this unit and the electrical outlet.
302
• The AC adaptor will begin to generate heat after long hours of
consecutive use. This is normal, and is not a cause for concern.
307
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions and/or
damage to speakers or other devices.
Placement
352a
• This device may interfere with radio and television reception.
Do not use this device in the vicinity of such receivers.
352b
• Noise may be produced if wireless communications devices,
such as cell phones, are operated in the vicinity of this unit.
Such noise could occur when receiving or initiating a call, or
while conversing. Should you experience such problems, you
should relocate such wireless devices so they are at a greater
distance from this unit, or switch them off.
354a
• Do not expose the unit to direct sunlight, place it near devices
that radiate heat, leave it inside an enclosed vehicle, or
otherwise subject it to temperature extremes. Excessive heat
can deform or discolor the unit.
355b
• When moved from one location to another where the
temperature and/or humidity is very different, water droplets
(condensation) may form inside the unit. Damage or
malfunction may result if you attempt to use the unit in this
condition. Therefore, before using the unit, you must allow it
to stand for several hours, until the condensation has
completely evaporated.
358
• Do not allow objects to remain on top of the keyboard. This
can be the cause of malfunction, such as keys ceasing to
produce sound.
360
• Depending on the material and temperature of the surface on
which you place the unit, its rubber feet may discolor or mar
the surface.
You can place a piece of felt or cloth under the rubber feet to
prevent this from happening. If you do so, please make sure
that the unit will not slip or move accidentally.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth or
one that has been slightly dampened with water. To remove
stubborn dirt, use a cloth impregnated with a mild, non-
abrasive detergent. Afterwards, be sure to wipe the unit
thoroughly with a soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of any kind, to
avoid the possibility of discoloration and/or deformation.
Repairs and Data
452
• Please be aware that all data contained in the unit’s memory
may be lost when the unit is sent for repairs. Important data
should always be backed up in your computer, or written
down on paper (when possible). During repairs, due care is
taken to avoid the loss of data. However, in certain cases (such
as when circuitry related to memory itself is out of order), we
regret that it may not be possible to restore the data, and
Roland assumes no liability concerning such loss of data.
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
losing important data, we recommend that you periodically
save a backup copy of important data you have stored in the
unit’s memory in your computer
.
552
• Unfortunately, it may be impossible to restore the contents of
data that was stored in your computer 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.
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.
561
• Use only the specified expression pedal (EV-5 or EV-7; sold
separately). By connecting any other expression pedals, you
risk causing malfunction and/or damage to the unit.
CD-ROM and DVD-ROM handling
801
• Do not touch the data surface (the unprinted surface) of the
disc, or allow it to be scratched. Doing so may make the data
unreadable. If the disc gets dirty, clean it using a commercially
available disc cleaner.
