Avoid extended use at high volume
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.
Don’t allow foreign objects or liquids to enter unit;
never place containers with liquid on unit
Do not place containers containing liquid on
this product. Never allow foreign objects (e.g.,
flammable objects, coins, wires) or liquids (e.g.,
water or juice) to enter this product. Doing so
may cause short circuits, faulty operation, or
other malfunctions.
Turn off the unit if an abnormality or malfunction
occurs
Immediately turn the unit 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; 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.
Adults must provide supervision in places where
children are present

unit can take place. An adult should always be
on hand to provide supervision and guidance.

WARNING
Do not share an outlet with an unreasonable
number of other devices
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.
Do not use overseas
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.

• Batteries must never be recharged, heated,
taken apart, or thrown into fire or water.
• Never expose batteries to excessive heat such
as sunshine, fire or the like.
• Incorrect handling of batteries can cause
leakage, overheating, fire, or explosion.
Before use, you must read and strictly observe
all of the precautions that accompany the
batteries.
