IMPORTANT NOTES

291a
In addition to the items listed under "USING THE UNIT SAFELY" on page 2 -3, please read and observe the
following:

Power Supply

301
• Do not use this unit on the same power circuit with
any device that will generate line noise (such as an
electric motor or variable lighting system).
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 temper-
ature 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.
Handling CD-ROMs
801
• Avoid touching or scratching the shiny underside
(encoded surface) of the disc. Damaged or dirty
CD-ROM discs may not be read properly. Keep
your discs clean using a commercially available
CD cleaner.

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 impreg-
nated with a mild, non-abrasive detergent. After-
wards, 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.
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 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.
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; sold
separately). By connecting any other expression
pedals, you risk causing malfunction and/or
damage to the unit.
