•
At regular intervals, you should unplug the power plug and
clean it by using a dry cloth to wipe all dust and other accumula-
tions away from its prongs. Also, disconnect the power plug from
the power outlet whenever the unit is to remain unused for an
extended period of time. Any accumulation of dust between the
power plug and the power outlet can result in poor insulation
and lead to fire.

IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2, 3 and 4,
please read and observe the following:
Power Supply
301
•
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.
307
•
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.
308
•
Although the LEDs are switched off when the POWER switch 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,
first turn off the POWER switch, then 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.
Placement
351
•
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.
352a
•
This device may interfere with radio and television reception. Do not use
this device in the vicinity of such receivers.
352b
•
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.
354b
•
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 temper-
ature 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.
355b
•
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.
356
•
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.
359
•
Do not paste stickers, decals, or the like to this instrument. Peeling such
matter off the instrument may damage the exterior finish.
Maintenance
401a
•
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.
402
•
Never use benzine, thinners, alcohol or solvents of any kind, to avoid the
possibility of discoloration and/or deformation.
Additional Precautions
553
•
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.
556
•
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.
557
•
A small amount of heat will radiate from the unit during normal operation.
558a
•
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).
559a
•
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 equiv-
alent packaging materials.
562
•
Some connection cables contain resistors. Do not use cables that incor-
porate 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.
921
•
To prevent malfunction and/or damage to speakers or other devices,
always turn down the volume, and turn off the power on all devices before
making any connections.
926a
•
When connection cables with resistors are used, the volume level of
equipment connected to the inputs (INPUT, AUX IN jacks) may be low. If
this happens, use connection cables that do not contain resistors.
941
• Once the connections have been completed, turn on power to your various
devices in the order specified. By turning on devices in the wrong order,
you risk causing malfunction and/or damage to speakers and other devices.
