IMPORTANT NOTES
Power Supply
• Do not connect this unit to same electrical outlet
that is being used by an electrical appliance that
is controlled by an inverter or a motor (such as a
refrigerator, washing machine, microwave oven, or
air conditioner). 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.
• The AC adaptor will begin to generate heat after
long hours of consecutive use. This is normal, and is
not a cause for concern.
• Place the AC adaptor so the side with the indicator
faces upwards. The indicator will light when you
plug the AC adaptor into an AC outlet.
Placement
• This unit may interfere with radio and television
reception. Do not use this unit in the vicinity of
such receivers.
• 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.
• 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.
• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet
may discolor or mar the surface.
• Do not place containers or anything else containing
liquid on top of this unit. Also, whenever any liquid
has been spilled on the surface of this unit, be sure
to promptly wipe it away using a soft, dry cloth.
Maintenance
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Care of the Keyboard
• Do not write on the keyboard with any pen or other
implement, and do not stamp or place any marking
on the instrument. Ink will seep into the surface
lines and become unremovable.
• Do not affix stickers on the keyboard. You
may be unable to remove stickers that use
strong adhesives, and the adhesive may cause
discoloration.
• To remove stubborn dirt, use a commercially
available keyboard cleaner that does not contain
abrasives. Start by wiping lightly. If the dirt does
not come off, wipe using gradually increasing
amounts of pressure while taking care not to
scratch the keys.
Repairs and Data
• Before sending the unit away for repairs, be sure to
make a backup of the data stored within it; or you
may prefer to write down the needed information.
Although we will do our utmost to preserve the
data stored in your unit when we carry out repairs,
in some cases, such as when the memory section
is physically damaged, restoration of the stored
content may be impossible. Roland assumes no
liability concerning the restoration of any stored
content that has been lost.
Additional Precautions
• Any data stored within the unit can be lost as the
result of equipment failure, incorrect operation,
etc. To protect yourself against the irretrievable
loss of data, try to make a habit of creating regular
backups of the data you’ve stored in the unit.
• Roland assumes no liability concerning the
restoration of any stored content that has been lost.
• 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.
• When 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.
• The sound of keys being struck and vibrations
produced by playing an instrument can be
transmitted through a floor or wall to an
unexpected extent. Please take care not to cause
annoyance to others nearby.
• Use only the specified expression pedal. By
connecting any other expression pedals, you risk
causing malfunction and/or damage to the unit.
• Continuous playing may cause dis-coloration of the
pad, but this will not affect the pad’s function.
