producing severed elements and short
circuits. Damaged cords are fire and shock
hazards!
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.

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

WARNING WARNING
Adults must provide supervision in places where
children are present
When using the unit in locations where
children are present, be careful so no
mishandling of the unit can take place.
An adult should always be on hand to
provide supervision and guidance.
Do not drop or subject to strong impact
Protect the unit from strong impact.
(Do not drop it!)
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 overseas, consult
with your retailer, the nearest Roland
Service Center, or an authorized Roland
distributor, as listed on the "Information"
page.
