IMPORTANT NOTES

291b

In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2

and 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.

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 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.

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 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.

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.

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.

• 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.

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 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.
