IMPORTANT NOTES

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.

354a

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. 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.

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.

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.

361

Do not put anything that contains water (e.g., flower vases) 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.

Maintenance

401a

For everyday cleaning wipe the unit with a soft, dry cloth or one that

has been slightly dampened with water. To remove stubborn dirt, use a

cloth impregnated with a mild, non-abrasive detergent. Afterwards, be

sure to wipe the unit thoroughly with a soft, dry cloth.

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 USB memories, 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 on USB memories.

552

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

that was stored in the unit’s memory, or USB memories 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.

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 / 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.

558d edit

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.

In particular, when using headphones, please take care not to cause

annoyance to others nearby.

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-5, EV-7; sold separately). By

connecting any other expression pedals, you risk causing malfunction

and/or damage to the unit.
