IMPORTANT NOTES

291b

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

3 and 4, 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.

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 accessible.

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 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.

355b

• When moved from one location to another where the temper-

ature 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

• 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.

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 in another MIDI device (e.g., a

sequencer), 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.

Additional Precautions

551

• 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 in another MIDI device (e.g., a sequencer).

552

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

data that was stored in the unit’s memory 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).

559a

• 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.

561

• Use only the specified expression pedal (EV-7; sold

separately). By connecting any other expression pedals, you

risk causing malfunction and/or damage to the unit.
