WARNING

When using the unit with a rack or stand recommended by
Roland, the rack or stand must be carefully placed so it is
level and sure to remain stable. If not using a rack or stand,
you still need to make sure that any location you choose for
placing the unit provides a level surface that will properly
support the unit, and keep it from wobbling.
Be sure to use only the AC adaptor supplied 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 adaptor’s 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 attached power-supply cord. Also, the supplied
power cord must not be used with any other device.
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!
This unit, either alone or in combination with an amplier
and 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.
