• 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 disconnect the USB cable,
and request servicing by your retailer,
the nearest Roland Service Center, or an
authorized Roland distributor, as listed on
the “Information” page when:
• Objects have fallen into, or liquid has
been spilled onto the unit; or
• If smoke or unusual odor occurs
• 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.
3
USING THE UNIT SAFETY
• 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 play a CD-ROM disc on a
conventional audio CD player. The resulting
sound may be of a level that could cause
permanent hearing loss. Damage to
speakers or other system components may
result.
• 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.
• Disconnect all cords coming from external
devices before moving the unit.

IMPORTANT NOTES
Power Supply
• Before connecting this unit to other devices, turn o the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other peripheral devices.
Placement
• Using the unit near power ampliers (or other
equipment containing large power transformers) may
induce hum. To alleviate the problem, change the
orientation of this unit; or move it farther away from the
source of interference.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicinity
of this unit. Such noise could occur when receiving
or initiating a call, or while conversing. Should you
experience such problems, you should relocate such
wireless devices so they are at a greater distance from
this unit, or switch them o.
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.
• When moved from one location to another where the
temperature and/or humidity is very dierent, water
droplets (condensation) may form inside the unit.
Damage or malfunction may result if you attempt to use
the unit in this condition. Therefore, before using the
unit, you must allow it to stand for several hours, until
the condensation has completely evaporated.
• Do not put anything that contains water (e.g., ower
vases) on this unit. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans, etc., near the
unit. Swiftly wipe away any liquid that spills on the unit
using a dry, soft cloth.
Maintenance
• For everyday cleaning wipe the unit with a soft, dry
cloth or one that has been slightly dampened with
water. To remove stubborn dirt, use a cloth impregnated
with a mild, non-abrasive detergent. Afterwards, be sure
to wipe the unit thoroughly with a soft, dry cloth.
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
Additional Precautions
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using
its jacks and connectors. Rough handling can lead to
malfunctions.
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way
you will avoid causing shorts, or damage to the cable’s
internal elements.
• To avoid disturbing your neighbors, try to keep the
unit’s volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you.
• When you need to transport the unit, package it in the
box (including padding) that it came in, if possible.
Otherwise, you will need to use equivalent packaging
materials.
• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level to
be extremely low, or impossible to hear. For information
on cable specications, contact the manufacturer of
the cable.
Handling CDs
• Avoid touching or scratching the shiny underside
(encoded surface) of the disc. Damaged or dirty CD discs
may not be read properly. Keep your discs clean using a
commercially available CD cleaner.
