USING THE UNIT SAFELY
010
This unit, either alone or in combination 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.

If you encounter any of the following
circumstances, immediately switch off the
power and disconnect the AC adaptor (if one is
being used) from the power outlet. And request
servicing by your retailer, the nearest Roland
Service Center, or an authorized Roland
distributor, as listed on the separate sheet titled
“Information” 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.

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.
