• 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.

 

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 
(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.

 

356

 

• Do not allow rubber, vinyl, or similar materials to remain on 

the unit for long periods of time. Such objects can discolor or 
otherwise harmfully affect the finish.

 

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.

 

359

 

• Do not paste stickers, decals, or the like to this instrument. 

Peeling such matter off the instrument may damage the 
exterior finish.

 

401b

 

• To clean the unit, use a dry, soft cloth; or one that is slightly 

dampened. Try to wipe the entire surface using an equal 
amount of strength, moving the cloth along with the grain of 
the wood. Rubbing too hard in the same area can damage the 
finish.

 

402

 

• Never use benzine, thinners, alcohol or solvents of any kind, 

to avoid the possibility of discoloration and/or deformation.

 

403

 

• The pedals of this unit are made of brass.

Brass eventually darkens as the result of the natural 
oxidization process. If the brass becomes tarnished, polish it 
using commercially available metal polisher.

 

552

 

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

data that was stored in the unit’s memory 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.

 

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.

 

560

 

• Do not apply undue force to the music stand while it is in use.

 

562

 

• Use a cable from Roland to make the connection. If using 

some other make of connection cable, please note the 
following precautions.

 

565

 

• Before opening or closing the keyboard lid, always make sure 

that no pets or other small animals are located on top of the 
instrument (in particular, they should be kept away from the 
keyboard and its lid). Otherwise, due to the structural design 
of this instrument, small pets or other animals could end up 
getting trapped inside it. If such a situation is encountered, 
you must immediately switch off the power and disconnect 
the power cord from the outlet. You should then consult with 
the retailer from whom the instrument was purchased, or 
contact the nearest Roland Service Center.

• Some connection cables contain resistors. Do not use cables 

that incorporate resistors for connecting to this unit. The use 
of such cables can cause the sound level to be extremely low, 
or impossible to hear. For information on cable specifications, 
contact the manufacturer of the cable.
