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 or a motor (such as a refrigerator,
washing machine, microwave oven, or air conditioner).
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.
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 unit may interfere with radio and television
reception. Do not use this unit 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
deform or discolor the unit.
• 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 place containers or anything else containing
liquid on top of this unit. Also, whenever any liquid
has been spilled on the surface of this unit, be sure to
promptly wipe it away using a soft, dry 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. 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
• 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 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 others nearby, try to keep the unit’s
volume at reasonable levels.
• When you need to transport the unit, pack it in shock-
absorbent material. Transporting the unit without doing
so can cause it to become scratched or damaged, and
could lead to malfunction.
