USING THE UNIT SAFELY

•

Immediately turn the power off, remove the AC

adaptor 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.

..................................................................................................................................

•

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 AC adaptor cord

when plugging into, or unplugging from, an outlet or

this unit.

..................................................................................................................................

•

At regular intervals, you should unplug the AC

adaptor 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 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.

• Fold down the music rest.

• Spread a piece of cloth between the keyboard and

the lid (music rest) before you close the lid.

..................................................................................................................................

•

Before cleaning the unit, turn off the power and

unplug the AC adaptor from the outlet (p. 18).
