Important Notes

Power Supply

301

• Do not connect this device to the same electrical outlet as an

inverter-controlled device such as a refrigerator, microwave

oven, or air conditioner, or a device that contains an electric

motor. Depending on how the other device is used, power

supply noise could cause this device to malfunction or produce

noise. If it is not practical to use a separate electrical outlet,

please connect this device via a power supply noise filter.

307

• Before you make connections, you must switch off the power

on all devices to prevent malfunction and/or speaker damage.

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

accessible.

Location

351

• If this device is placed near devices that contain large

transformers, such as power amps, hum may be induced in

this device. If this occurs, move this device farther away or

change its orientation.

352a

• If this device is operated near a television or radio, color

distortion may be seen in the television screen or noise may be

heard from the radio. If this occurs, move this device farther

away.

352b

• Keep your cell phone powered off or at a sufficient distance

from this device. If a cell phone is nearby, noise may be heard

when a call is received or initiated, or during conversation.

354b

• Do not leave this device in direct sunlight, near devices that

produce heat, or in a closed-up automobile. Do not allow

illumination devices operated in close proximity (such as a

piano light) or powerful spotlights to shine on the same

location on this device for an extended time. This can cause

deformation or color change.

355b

• If you move this device between locations of radically different

temperature or humidity, water droplets (condensation) may

form inside the device. Using the device in this condition will

cause malfunctions, so please allow several hours for the

condensation to disappear before you use the device.

356

• Do not allow items made of rubber or vinyl to remain on top of

this device for an extended time. This can cause deformation

or color change.

358

• Do not allow objects to remain on top of the keyboard or

pedal board. This can be the cause of malfunction, such as

keys ceasing to produce sound.

359

• Do not affix adhesive labels to this device. The exterior finish

may be damaged when you remove the labels.

360

• 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.

Care

401b

• For everyday care, wipe with a soft dry cloth, or remove

stubborn dirt using a tightly wrung-out cloth. If this device

contains wooden components, wipe the entire area following

the direction of the grain. The finish may be damaged if you

continue strongly rubbing a single location.

Addition

• If water droplets should adhere to this device, immediately

wipe them off using a soft dry cloth.

402

• Do not use solvents such as benzene, thinner, or alcohol, since

these can cause deformation or color change.

Servicing

452

• If you return this device for servicing, the contents of memory

may be lost. Please store important contents on USB memory,

or make a note of the contents. We take utmost care to

preserve the contents of memory when performing service, but

there may be cases when the stored content cannot be

recovered because the memory section has malfunctioned.

Please be aware that we cannot accept responsibility for the

recovery of lost memory content or for any consequences of

such loss.

Other Cautions

551

• Stored content may be lost due to a malfunction of the device

or because of inadvertent operation. You should back up

important content on USB memory as a safeguard against

such loss.

552

• We cannot accept responsibility for the recovery of any

content lost from internal memory or USB memory, or for the

consequences of such loss.

553

• Do not apply excessive force to the buttons, knobs, or input/

output jacks, since this may cause malfunctions.

554

• Never strike or apply strong pressure to the display.

555

• A small amount of noise may be heard from the display during

normal operation.

556

• When connecting or disconnecting cables, grasp the plug (not

the cable) to prevent short circuits or broken connections.

557

• This device may produce a certain amount of heat, but this is

not a malfunction.

558a

• Please enjoy your music in ways that do not inconvenience

other people nearby, and pay particular attention to the

volume at nighttime. Using headphones will allow you to enjoy

music without having to be concerned about others.

559b

• When transporting or shipping this device, package it in an

appropriate amount of cushioning material. Scratches,

damage, or malfunctions may occur if you transport it without

appropriate packaging.

560

• If using the music rest, do not apply excessive force to it.

562

• Some connection cables contain a resistor. Do not connect

such cables to this device. Doing so may make the volume

extremely low or inaudible. Please use connection cables not

containing a resistor.

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.

566b

• The sensitivity of the D Beam controller will change depending

on the amount of light in the vicinity of the unit. If it does not

function as you expect, adjust the sensitivity as appropriate for

the brightness of your location.
