USING THE UNIT SAFELY
WARNING
Do not attempt to repair the unit, or replace parts within it (except when
this manual provides specic instructions directing you to do so). Refer all
servicing to your retailer, the nearest Roland Service Center, or an autho-
rized 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 oors); 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 specied on
the AC adaptor’s body. Other AC adaptors may use a dierent polarity, or
be designed for a dierent 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 amplier 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 place containers containing liquid on this product. Never allow
foreign objects (e.g., ammable objects, coins, wires) or liquids (e.g., water
or juice) to enter this product. Doing so may cause short circuits, faulty
operation, or other malfunctions.
Immediately turn the power o, 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.
WARNING
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.
CAUTION
The unit and the AC adaptor should be located so their location or position
does not interfere with their proper ventilation.
Always grasp only the plug on the AC adaptor 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 accumula-
tion of dust between the power plug and the power outlet can result in
poor insulation and lead to re.
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.
Never handle the AC adaptor or its plugs with wet hands when plugging
into, or unplugging from, an outlet or this unit.
Before moving the unit, disconnect the AC adaptor and all cords coming
from external devices.
Before cleaning the unit, turn o the power and unplug the AC adaptor
from the outlet (p.8).
Whenever you suspect the possibility of lightning in your area, disconnect
the AC adaptor from the outlet.
Keep the ground terminal screw and/or USB connector cap you may
remove in a safe place out of children’s reach, so there is no chance of them
being swallowed accidentally.
