Use only the supplied AC adaptor and the correct
voltage
Be sure to use only the AC adaptor
included with the unit. Also, make sure
the line voltage at the installation matches
the input voltage specied on the AC
adaptor’s body. Other AC adaptors may
use a dierent polarity, or be designed
for a dierent voltage, so their use could
result in damage, malfunction, or electric
shock.
Use only the included power cord
Use only the attached power-supply cord.
Also, the included power cord must not be
used with any other device.
WARNING
Do not bend the power cord or place heavy objects
on it
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 re and shock hazards!
Avoid extended use at high volume
This unit, either alone or in combination
with an amplier 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
(e.g., ower vases) on this product. Never
allow foreign objects (e.g., ammable
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 o the unit if an abnormality or malfunction
occurs
Immediately turn the unit o, remove the
AC adaptor from the outlet, and request
servicing by your retailer, the nearest
Roland Service Center, or an authorized

performance.
WARNING
Adults must provide supervision in places 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 a foreign country,
consult with your retailer, the nearest
Roland Service Center, or an authorized
Roland distributor, as listed on the
“Information” page.
