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.
• 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.
• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet
may discolor or mar the surface.
• 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
• 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.
• Do not use connection cables that contain a built-in
resistor.
