IMPORTANT NOTES
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 LCD and 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 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.
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.
360
•
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.

Maintenance
401b
•
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.
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
equivalent packaging materials.
562
•
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.
•
Be sure to avoid inserting your fingers in the bass reflex ports when
transporting or moving the speakers, as your fingers may become
wedged and stuck in the ports.
