USING THE UNIT SAFELY
•
Do not allow any objects (e.g., flammable material,
coins, pins); or liquids of any kind (water, soft drinks,
etc.) to penetrate the unit.
..................................................................................................................................
•
Immediately turn the power off, remove the power
cord from the outlet, and request servicing by your
retailer, the nearest Roland Service Center, or an
authorized Roland distributor, as listed on the
“Information” page when:
• The AC adaptor, the power-supply cord, or the
plug has been damaged; or
• If smoke or unusual odor occurs
• Objects have fallen into, or liquid has been spilled
onto the unit; or
• The unit has been exposed to rain (or otherwise
has become wet); or
• The unit does not appear to operate normally or
exhibits a marked change in performance.
..................................................................................................................................
•
In households with small children, an adult should
provide supervision until the child is capable of
following all the rules essential for the safe operation
of the unit.
..................................................................................................................................
•
Protect the unit from strong impact.
(Do not drop it!)
..................................................................................................................................
•
Do not force the unit’s power-supply cord to share an
outlet with an unreasonable number of other devices.
Be especially careful when using extension cords—
the total power used by all devices you have
connected to the extension cord’s outlet must never
exceed the power rating (watts/amperes) for the
extension cord. Excessive loads can cause the
insulation on the cord to heat up and eventually melt
through.
..................................................................................................................................
•
Before using the unit in a foreign country, consult
with your retailer, the nearest Roland Service Center,
or an authorized Roland distributor, as listed on the
“Information” page.
..................................................................................................................................
•
DO NOT play a CD-ROM disc on a conventional audio
CD player. The resulting sound may be of a level that
could cause permanent hearing loss. Damage to
speakers or other system components may result.
..................................................................................................................................
•
Do not put anything that contains water (e.g., flower
vases) on this unit. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans, etc., near
the unit. Swiftly wipe away any liquid that spills on
the unit using a dry, soft cloth.
..................................................................................................................................
•
The unit and the AC adaptor should be located so
their location or position does not interfere with their
proper ventilation.
..................................................................................................................................
•
Always grasp only the plug on the power-supply cord
and the AC adaptor when plugging into, or
unplugging from, an outlet or this unit.
..................................................................................................................................
• At regular intervals, you should unplug the power
plug and clean it by using a dry cloth to wipe all dust
and other accumulations away from its prongs. Also,
disconnect the power plug from the power outlet
whenever the unit is to remain unused for an
extended period of time. Any accumulation of dust
between the power plug and the power outlet can
result in poor insulation and lead to fire.
..................................................................................................................................
• Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be
placed so they are out of the reach of children.
..................................................................................................................................
• Never climb on top of, nor place heavy objects on the
unit.
..................................................................................................................................
•
Never handle the power cord and the AC adaptor or
its plugs with wet hands when plugging into, or
unplugging from, an outlet or this unit.
..................................................................................................................................

If you need to move the instrument, take note of the
precautions listed below. At least two persons are
required to safely lift and move the unit. It should be
handled carefully, all the while keeping it level. Make
sure to have a firm grip, to protect yourself from injury
and the instrument from damage.
• Check to make sure the screws securing the unit to
the stand have not become loose. Fasten them
again securely whenever you notice any loosening.
• Disconnect the power cord.
• Disconnect all cords coming from external devices.
• Raise the adjusters on the stand (p. 22).
• Close the lid.
• Remove the music stand (HP302).

Before cleaning the unit, turn off the power and
unplug the power cord from the outlet (p. 18).
..................................................................................................................................
•
Whenever you suspect the possibility of lightning in
your area, pull the plug on the power cord out of the
outlet.
