• 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.

 

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.

 

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.

 

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.

 

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.

 

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.
