within it (except when this manual provides
specific instructions directing you to do so). Refer
all servicing to your retailer, the nearest Roland Service
Center, or an authorized Roland distributor, as listed on
the “Information” page.
................................................................................................

• Never use or store the unit in places that are:

• Make sure you always have the unit placed so it is
level and sure to remain stable. Never place it on
stands that could wobble, or on inclined surfaces.
................................................................................................
008c
• 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 specified on
the AC adaptor’s body. Other AC adaptors may use a
different polarity, or be designed for a different voltage, so
their use could result in damage, malfunction, or electric
shock.
................................................................................................
008e
• 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 fire and shock hazards!
................................................................................................

• 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 uncom-
fortable. If you experience any hearing loss or ringing in
the ears, you should immediately stop using the unit, and
consult an audiologist.
