IMPORTANT NOTES

•  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.

•  To prevent malfunction and equipment failure, 

always make sure to turn off the power on all your 
equipment before you make any connections.

•  With the factory settings, the unit will automatically 

be switched off 30 minutes after you stop playing 
or operating the unit. If the unit’s power has been 
turned off automatically, you can use the [Power] 
switch to turn the unit back on again. If you don’t 
want the unit to turn off automatically, change the 
“Auto Off” setting to “Off” as described on “Making 
the Power Automatically Turn Off After a Time (Auto 
Off)” (p. 39).

The settings you were editing will be lost when the 
unit is turned off. If you want to keep your settings, 
you must save your settings before turning the unit 
off.

•  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 this 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.

•  Depending on the material and temperature of the 

surface on which you place the unit, its rubber feet 
may discolor or mar the surface. 
You can place a piece of felt or cloth under the 
rubber feet to prevent this from happening. If you 
do so, please make sure that the unit will not slip or 
move accidentally.

•  Do not put anything that contains water on this unit. 

Also, avoid the use of insecticides, perfumes, alcohol, 
nail polish, spray cans, etc., near the unit. Swiftly 
wipe away any liquid that spills on the unit using a 
dry, soft cloth.

•  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.

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.

•  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.
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 
detergents, since they might deteriorate the surface 
of the cabinet, and produce cracks. Do not use 
dusting cloths that contain chemicals.

•  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.

•  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 flash drives, 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.

•  Please be aware that the contents of memory can 

be irretrievably lost as a result of a malfunction, 
or the improper operation of the unit. To protect 
yourself against the risk of loosing important data, 
we recommend that you periodically save a backup 
copy of important data you have stored in the unit’s 
memory on a USB flash drive.

•  Unfortunately, it may be impossible to restore 

the contents of data that was stored in the unit’s 
memory, USB flash drives once it has been lost. 
Roland Corporation assumes no liability concerning 
such loss of data.

•  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.

•  Never strike or apply strong pressure to the display.

•  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.

•  To avoid disturbing others nearby, try to keep the 

unit’s volume at reasonable levels. You may prefer 
to use headphones, so you do not need to be 
concerned about those around you.

•  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.

•  When you need to transport the unit, package it 

in the box (including padding) that it came in, if 
possible. Otherwise, you will need to use equivalent 
packaging materials.

•  Do not apply undue force to the music rest while it 

is in use.

•  Some connection cables contain resistors. Do not 

use cables that incorporate resistors for connecting 
to this unit. The use of such cables can cause the 
sound level to be extremely low, or impossible to 
hear. For information on cable specifications, contact 
the manufacturer of the cable.
