Important Notes

In addition to the items listed under “USING THE UNIT SAFELY” on page 2 and 3, 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. If it is not practical to use a separate
electrical outlet, connect a power supply noise filter
between this unit and the electrical outlet.

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 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.

Placement

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 initi-
ating 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.

354b

• 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.
Also, do not allow lighting devices that normally are used
while their light source is very close to the unit (such as a
piano light), or powerful spotlights to shine upon the
same area of the unit for extended periods of time.
Excessive heat can deform or discolor the unit.

355b

• 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.

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 or

pedal board. 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.

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.

Maintenance

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.

Additional Precautions

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.

558b

• To avoid disturbing your neighbors, try to keep the unit’s
