IMPORTANT NOTES

Power Supply

• Do not connect this unit to same electrical outlet

that is being used by an electrical appliance that

is controlled by an inverter or a motor (such as a

refrigerator, washing machine, microwave oven, or

air conditioner). 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.

• The AC adaptor will begin to generate heat after

long hours of consecutive use. This is normal, and is

not a cause for concern.

Placement

• 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.

• This unit may interfere with radio and television

reception. Do not use this unit in the vicinity of such

receivers.

• 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.

• 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.

• 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.

• Depending on the material and temperature of the

surface on which you place the unit, its rubber feet

may discolor or mar the surface.

• Do not place containers or anything else containing

liquid on top of this unit. Also, whenever any liquid

has been spilled on the surface of this unit, be sure

to promptly wipe it away using a soft, dry cloth.

Maintenance

• Never use benzine, thinners, alcohol or solvents of

any kind, to avoid the possibility of discoloration

and/or deformation.

Repairs and Data

• Before sending the unit away for repairs, be sure to

make a backup of the data stored within it; or you

may prefer to write down the needed information.

Although we will do our utmost to preserve the

data stored in your unit when we carry out repairs,

in some cases, such as when the memory section

is physically damaged, restoration of the stored

content may be impossible. Roland assumes no

liability concerning the restoration of any stored

content that has been lost.

Additional Precautions

• Any data stored within the unit can be lost as the

result of equipment failure, incorrect operation, etc.

To protect yourself against the irretrievable loss of

data, try to make a habit of creating regular backups

of the data you’ve stored in the unit.

• Roland assumes no liability concerning the

restoration of any stored content that has been lost.

• 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.

• Never strike or apply strong pressure to the display.

• When 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.

• To avoid disturbing others nearby, try to keep the

unit’s volume at reasonable levels.

• 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. Please take care not to cause

annoyance to others nearby.

• Do not apply undue force to the music stand while

it is in use.

• Use only the specified expression pedal (EV-5; sold

separately). By connecting any other expression

pedals, you risk causing malfunction and/or

damage to the unit.

• Continuous playing may cause dis-coloration of the

pad, but this will not affect the pad’s function.

• Do not use connection cables that contain a built-in

resistor.

Using External Memories

• Please observe the following precautions when

handling external memory devices. Also, make sure

to carefully observe all the precautions that were

supplied with the external memory device.

• Do not remove the device while reading/writing

is in progress.

• To prevent damage from static electricity,

discharge all static electricity from your person

before handling the device.

Ground Terminal

• Depending on the circumstances of a particular

setup, you may experience a discomforting

sensation, or perceive that the surface feels

gritty to the touch when you touch this device,

microphones connected to it, or the metal portions

of other objects, such as guitars. This is due to an

infinitesimal electrical charge, which is absolutely

harmless. However, if you are concerned about this,

connect the ground terminal (see figure) with an

external ground. When the unit is grounded, a slight

hum may occur, depending on the particulars of

your installation. If you are unsure of the connection

method, contact the nearest Roland Service Center,

or an authorized Roland distributor, as listed on the

“Information” page.

Unsuitable places for connection

• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may be

dangerous in the event of lightning)
