• 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.

• Avoid damaging the power cord. Do not bend it
excessively, step on it, place heavy objects on it,
etc. A damaged cord can easily become a shock or
fire hazard. Never use a power cord after it has
been damaged.

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.

• 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.

with your retailer, the nearest Roland Service
Center, or an authorized Roland distributor, as
