Important Notes

In addition to the “USING THE UNIT SAFELY” listed on page 7, please observe the following cautions.

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.

302

• The AC adaptor will begin to generate heat after long

hours of consecutive use. This is normal, and is not a cause
for concern.

307

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

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

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 leave objects on top of the keyboard. This can

cause malfunctions such as failure to 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

• 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.

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 another MIDI device (e.g., a
sequencer) as a safeguard against such loss.

552

• We cannot accept responsibility for the recovery of any

content lost from internal 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.

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.
