301

 

• Do not use this unit on the same power circuit with any 

device that will generate line noise (such as an electric motor 
or variable lighting system).

 

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.

 

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.

 

355

 

• To avoid possible breakdown, do not use the unit in a wet 

area, such as an area exposed to rain or other moisture.

 

356

 

• Do not allow rubber, vinyl, or similar materials to remain on 

the piano 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.

 

401b

 

• 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.

 

402

 

• 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 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.

 

•

 

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 dusting cloths that contain chemicals.

 

552

 

• Unfortunately, it may be impossible to restore the contents of 

data that was stored in another MIDI device (e.g., a 
sequencer) once it has been lost. Roland Corporation assumes 
no liability concerning such loss of data.

 

553

 

• 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.

 

556

 

• When connecting / 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.

 

557

 

• A small amount of heat will radiate from the unit during 

normal operation.

 

558a

 

• To avoid disturbing your neighbors, 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 (especially when it is late at night).

 

559b

 

•  When you need to transport the unit, pack it in shock-

absorbent material. Transporting the unit without doing so 
can cause it to become scratched or damaged, and could lead 
to malfunction.

 

562

 

• Use a cable from Roland to make the connection. If using 

some other make of connection cable, please note the 
following precautions.

• 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.

 

565

 

• Before opening or closing the keyboard lid, always make sure 

that no pets or other small animals are located on top of the 
instrument (in particular, they should be kept away from the 
keyboard and its lid). Otherwise, due to the structural design 
of this instrument, small pets or other animals could end up 
getting trapped inside it. If such a situation is encountered, 
you must immediately switch off the power and disconnect 
the power cord from the outlet. You should then consult with 
the retailer from whom the instrument was purchased, or 
contact the nearest Roland Service Center.
