IMPORTANT NOTES
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.
• Before connecting this unit to other devices, turn
off all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
• Although the LED is switched off, this does
not mean that the unit has been completely
disconnected from the source of power. If you
need to turn off the power completely, unplug the
power cord from the power outlet. For this reason,
the outlet into which you choose to connect the
power cord's plug should be one that is within
easy reach and readily accessible.
• With the factory settings, the CM-110 and CM-220
will automatically be switched off approximately
4 hours after you stop playing or operating the
unit. If you don't want the power to turn off
automatically, change the "AUTO OFF" setting to
"OFF" as described on p. 6.
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 temperature 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 this unit for long periods of time. Such
objects can discolor or otherwise harmfully affect
the finish.
• 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 accidentally.
• 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
• 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.
• A small amount of heat will radiate from the unit
during normal operation.
• 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
specifications, contact the manufacturer of the
cable.
• Otherwise, due to the structural design of this
instrument, small pets or other animals could end
up getting trapped inside it. If such a situation
is encountered, you must immediately turn off
the unit and disconnect the power cord from the
outlet. You should then consult with the retailer
from whom the instrument was purchased, or
contact the nearest Roland Service Center.
• Do not insert hands, fingers, etc, into the openings
in the unit. In particular, if the unit is to used in
households with small children, always provide
adult supervision to ensure that children keep
their hands and feet out of these openings.
