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 install the unit in any of the following
locations.
• Subject to temperature extremes (e.g., direct
sunlight in an enclosed vehicle, near a heating
duct, on top of heat-generating equipment);
or are
• Damp (e.g., baths, washrooms, on wet floors);
or are
• Exposed to steam or smoke; or are
• Subject to salt exposure; or are
• Humid; or are
• Exposed to rain; or are
• Dusty or sandy; or are
• Subject to high levels of vibration and
shakiness.
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.
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.
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 uncomfort-
able. If you experience any hearing loss or
ringing in the ears, you should immediately
stop using the unit, and consult an audiologist.
Do not allow any objects (e.g., flammable
material, coins, pins); or liquids of any kind
(water, soft drinks, etc.) to penetrate the unit.
WARNING
Immediately turn the power off, remove the AC
adaptor from the outlet, and request servicing
by your retailer, the nearest Roland Service
Center, or an authorized Roland distributor, as
listed on the “Information” page when:
• The AC adaptor, the power-supply cord, or the
plug has been damaged; or
• If smoke or unusual odor occurs
• Objects have fallen into, or liquid has been
spilled onto the unit; or
• The unit has been exposed to rain (or otherwise
has become wet); or
• The unit does not appear to operate normally
or exhibits a marked change in performance.
In households with small children, an adult
should provide supervision until the child is
capable of following all the rules essential for
the safe operation of the unit.
Protect the unit from strong impact.
(Do not drop it!)
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.
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.
Batteries must never be recharged, heated,
taken apart, or thrown into fire or water.
Never expose Battery to excessive heat such as
sunshine, fire or the like.
CAUTION
The unit and the AC adaptor should be located
so their location or position does not interfere
with their proper ventilation.

cord when plugging into, or unplugging from,
an outlet or this unit.
At regular intervals, you should unplug the AC
adaptor and clean it by using a dry cloth to
wipe all dust and other accumulations away
from its prongs. Also, disconnect the power
plug from the power outlet whenever the unit
is to remain unused for an extended period of
time. Any accumulation of dust between the
power plug and the power outlet can result in
poor insulation and lead to fire.
CAUTION
Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be
placed so they are out of the reach of children.
Never climb on top of, nor place heavy objects
on the unit.

adaptor and all cords coming from external
devices.
Before cleaning the unit, turn off the power
and unplug the AC adaptor from the outlet
(p. 4).
