IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages
3–5, please read and observe the following:
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.

306b
• Batteries are supplied with the unit. The life of these
batteries may be limited, however, since their primary
purpose was to enable testing.
purpose was to enable testing.
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.
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 acces-
sible.

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 inter-
ference.

• 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 initi-
ating 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.

• 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.

• Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.

Maintenance
401b (edit)
• 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.
careful, periodic care. A few important suggestions

• 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.

• If the cabinet’s surface loses its luster, wipe it
thoroughly with a soft cloth dampened with a little of
the polishing liquid. Do not use any cleaners or deter-
gents, since they might deteriorate the surface of the
cabinet, and produce cracks. Do not use dusting cloths
that contain chemicals.

• 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 USB memory
or floppy disk, 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.
