IMPORTANT NOTES

291b

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

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 temper-
ature and/or humidity is very different, water droplets (conden-
sation) 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.

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

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-5/7; sold
separately). By connecting any other expression pedals, you risk
causing malfunction and/or damage to the unit.

Handling CD-ROMs

801

• Avoid touching or scratching the shiny underside (encoded
surface) of the disc. Damaged or dirty CD-ROM discs may not be
read properly. Keep your discs clean using a commercially
available CD cleaner.
