IMPORTANT NOTES
291b
and 4–5, please read and observe the following:
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.
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 initi-
ating 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.
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.
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.
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 defor-
mation.
853
•
Do not use this unit for purposes that could infringe on a
copyright held by a third party. We assume no responsi-
bility whatsoever with regard to any infringements of third-
party copyrights arising through your use of this unit.
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.
554
•
Never strike or apply strong pressure to the display.
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.
558b
•
To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels (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.
