IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 6, 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 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.
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.
Handling CD-ROMs
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 commer-
cially available CD cleaner.
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 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.
