IMPORTANT NOTES

291a

In addition to the items listed under “USING THE UNIT SAFELY” on pages 8–9, 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.

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

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 inter-
ference.

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.

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

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.

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.

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

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 a
computer, 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.
