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.

Although the LCD and LEDs are switched off when the POWER
switch is switched off, this does not mean that the unit has
been completely disconnected from the source of power. If
you need to turn off the power completely, first turn off the
POWER switch, then unplug the power cord from the power
outlet. For this reason, the outlet into which you choose to
connect the power cord’s plug should be one that is within
easy reach and readily accessible.

Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum. To
alleviate the problem, change the orientation of this unit; or
move it farther away from the source of interference.

•
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.

•
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. Also, do not
allow lighting devices that normally are used while their light
source is very close to the unit (such as a piano light), or
powerful spotlights to shine upon the same area of the unit
for extended periods of time. Excessive heat can deform or
discolor the unit.

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.

Maintenance
•
Since your piano has a polished finish that is as delicate as that
found on finely crafted wooden furniture, it needs careful,
periodic care. A few important suggestions concerning the
proper care of the unit follow.

For dusting, using a soft, clean cloth and/or piano-use
feather duster. Be sure to wipe gently. Even the tiniest
grains of sand or grit can leave scratches on the surface if
too much force is applied while wiping. Do not use any
cleaners or detergents, since they might deteriorate the
surface of the cabinet, and produce cracks.

•
To clean other part, use a dry, soft cloth; or one that is slightly
dampened. Try to wipe the entire surface using an equal
amount of strength, moving the cloth along with the grain of
the wood. Rubbing too hard in the same area can damage the
finish.

The pedals of this unit are made of brass.
Brass eventually darkens as the result of the natural
oxidization process. If the brass becomes tarnished, polish it
using commercially available metal polisher.

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 on a USB memory, 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.
