Use only the specified AC adaptor,

and make sure the line voltage at the installation matches the input voltage specified on the AC adaptor’s body. Other AC adaptors may use a different polarity, or be designed for a different voltage, so their use could result in damage, malfunction, or electric shock.

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

Do not excessively twist or bend the power cord, nor place heavy objects on it. Doing so can damage the cord, producing severed elements and short circuits. Damaged cords are fire and shock

hazards!

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

This unit, either alone or in combi- nation with an amplifier and headphones or speakers, may be capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high volume level, or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should immediately stop using the unit, and consult an

audiologist.

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

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 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 or the power- supply cord has been damaged; or

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 super- vision 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 unrea- sonable 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.
