USING THE UNIT SAFELY
Avoid extended use at high volume
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 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 insert foreign objects
Do not allow any objects (e.g., flammable
material, coins, pins); or liquids of any kind
(water, soft drinks, etc.) to penetrate the unit.
......................................................................................................................
Turn off the power if an abnormality or
malfunction occurs
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.
......................................................................................................................
Do not allow children to use without supervision
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.
......................................................................................................................
Do not drop or subject to strong impact
Protect the unit from strong impact.
(Do not drop it!)
......................................................................................................................
Do not share an outlet with 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.
......................................................................................................................
Before using the unit in a foreign country
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.
Place in a well ventilated location
The unit and the AC adaptor should be located
so their location or position does not interfere
with their proper ventilation.
......................................................................................................................
Grasp the plug when connecting or disconnecting
the power cord
Always grasp only the plug on the AC adaptor
cord when plugging into, or unplugging from, an
outlet or this unit.
......................................................................................................................
Periodically wipe the dust off the AC adaptor plug
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.
......................................................................................................................
Manage cables for safety
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.
