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 (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.
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.
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
 
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.
This device may interfere with radio and television reception. Do not 
use this device in the vicinity of such receivers.
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.
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 allow objects to remain on top of the keyboard. This can be 
the cause of malfunction, such as keys ceasing to produce sound.
Do not paste stickers, decals, or the like to this instrument. Peeling 
such matter off the instrument may damage the exterior finish.
 
Maintenance
 
To clean the unit, 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.
Never use benzine, thinners, alcohol or solvents of any kind, to avoid 
the possibility of discoloration and/or deformation.
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.
Since wood will expand and contract depending on how it is used 
and the environment in which it is located, products made of wood 
may experience a gradual loosening of the screws over time. 
To ensure that your piano remains in safe, optimal condition, you 
should regularly check the tightness of the screws in the locations 
shown in the illustration. If you find that any screws are loose, use a 
screwdriver to tighten them.
 
Maintenance (Polished-finish pianos)
 
Since your piano has a polished finish that is as delicate as that found 
on finely crafted wooden furniture, it needs careful, periodic care. 
For regular dusting, use a soft, clean cloth and/or a piano-use 
feather duster. Be sure to wipe gently. Even tiny granules of grit 
can damage the surface of the unit if you use too much pressure 
when wiping.
If the cabinet gets dirty, wipe it with a soft cloth that has been 
soaked with water, then squeezed dry. Afterwards, wipe it again 
with a soft dry cloth. 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.
If the cabinet’s surface loses its luster, wipe it thoroughly with a 
soft cloth dampened with a little of the piano polishing liquid.
About piano polishing liquid
Use polishing liquid as directed by the instructions for the 
product.
Use only polishing liquid that is intended for use on polished-
finish pianos. Using any other polishing liquid may cause 
scratches, deformation, or discoloration. To purchase polishing 
liquid, contact your nearby musical instrument dealer.
Use the polishing liquid only on the polished surfaces of the 
cabinet. Always wipe the surface with the grain using straight, 
even strokes. Do not repeatedly wipe the same places using too 
much pressure, since that might result in the loss of luster.
Be sure to keep the polishing liquid out of the reach of small 
children. If the polishing liquid is accidentally swallowed, first get 
them to vomit, then take them to a doctor.
 
Repairs and Data
 
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.
