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.
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.
308
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.
Placement
351
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.
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.
354b
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.
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.
356
Do not allow rubber, vinyl, or similar materials to remain on
the unit for long periods of time. Such objects can discolor or
otherwise harmfully affect the finish.
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.
359
Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.
add
This unit is designed to be stable. However, if you are placing
it at a distance from the wall, please install the included anti-
tipping hardware to ensure maximum safety.
For details on installing the anti-tipping hardware, refer to the
assembly leaflet.
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.
Do not use any cleaners or detergents, since they might
deteriorate the surface of the cabinet, and produce cracks.
Do not use dusting cloths that contain chemicals.
401b
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.
402
Never use benzine, thinners, alcohol or solvents of any kind, to
avoid the possibility of discoloration and/or deformation.
403
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.
