IMPORTANT NOTES
In addition to the items listed under “USING THE UNIT SAFELY” on p. 4, please read and observe the following:
Power Supply
• Do not connect this unit to same electrical outlet that is being
used by an electrical appliance that is controlled by an
inverter (such as a refrigerator, washing machine, microwave
oven, or air conditioner), or that contains a motor. Depending
on the way in which the electrical appliance is used, power
supply noise may cause this unit to malfunction or may
produce audible noise. If it is not practical to use a separate
electrical outlet, connect a power supply noise filter between
this unit and the electrical outlet.
• The AC adaptor will begin to generate heat after long hours
of consecutive use. This is normal, and is not a cause for
concern.
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions and/
or damage to speakers or other devices.
Placement
• Using the unit near power amplifiers (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 off.
•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. Also, do not
allow lighting devices that normally are used while their light
source is very close to the unit (such as a piano light), or
powerful spotlights to shine upon the same area of the unit
for extended periods of time. Excessive heat can deform or
discolor the unit.
• When moved from one location to another where the temper-
ature and/or humidity is very different, 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 allow rubber, vinyl, or similar materials to remain on
the unit for long periods of time. Such objects can discolor or
otherwise harmfully affect the finish.
• Do not allow objects to remain on top of the keyboard. This
can be the cause of malfunction, such as keys ceasing to
produce sound.
• Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.
•Depending on the material and temperature of the surface on
which you place the unit, its rubber feet may discolor or mar
the surface. You can place a piece of felt or cloth under the
rubber feet to prevent this from happening. If you do so,
please make sure that the unit will not slip or move acciden-
tally.
• Do not put anything that contains water (e.g., flower 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
• To clean the unit, use a dry, soft cloth; or one that is slightly
dampened. Try to wipe the entire surface using an equal
amount of strength, moving the cloth along with the grain of
the wood. Rubbing too hard in the same area can damage the
finish.
• Never use benzine, thinners, alcohol or solvents of any kind,
to avoid the possibility of discoloration and/or deformation.
Additional Precautions
•Unfortunately, it may be impossible to restore the contents of
data that was stored on a USB storage device once it has been
lost. Roland Europe assumes no liability concerning such loss
of data.
• 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 (especially when it is late at night).
• 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.
•Do not apply undue force to the music stand while it is in use.
• Use only the specified expression pedal (EV-7 or EV-5; sold
separately). By connecting any other expression pedals, you
risk causing malfunction and/or damage to the unit.
Using USB Memory
• When connecting USB memory, firmly insert it all the way
into the USB memory port.
•Do not touch the pins of the USB memory port, or allow them
to become dirty.
• USB memory is made using high-precision electronic compo-
nents, so please observe the following points when handling
it.
• To prevent damage from static electrical charges,
discharge any static electricity that might be present in
your body before handling USB memory.
•Do not touch the terminals with your fingers or any metal
object.
• Do not bend or drop USB memory, or subject it to strong
impact.
• Do not leave USB memory in direct sunlight or in
locations such as a closed-up automobile. (Storage
temperature: 0~50°C)
• Do not allow USB memory to become wet.
• Do not disassemble or modify USB memory.
• When connecting USB memory, position it horizontally with
the C-200’s USB Memory port and insert it without using
excessive force. The USB memory connector may be damaged
if you use excessive force when inserting USB memory.
