should be read before the appliance is operated.
2. Retain Instructions The safety and operating instructions
should be retained for future reference.
3. Heed Warnings All warnings on the appliance and in the
operating instructions should be adhered to.
4. Follow Instructions All operating and use instructions
should be followed.
5. Cleaning Unplug the appliance from the wall outlet before
cleaning. The appliance should be cleaned only as recom-
mended by the manufacturer.
6. Attachments Do not use attachments not recommended by
the appliance manufacturer as they may cause hazards.
7. Water and Moisture Do not use the appliance near water for
example, near a bath tub, wash bowl, kitchen sink, or laundry
tub; in a wet basement; or near a swimming pool; and the like.
8. Accessories Do not place the appliance on an unstable cart,
stand, tripod, bracket, or table. The appliance may fall, causing
serious injury to a child or adult, and serious damage to the
appliance. Use only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with the appliance.
Any mounting of the appliance
turer's instructions, and should
use a mounting accessory rec-
ommended by the manufacturer.
9. An appliance and cart combina-
tion should be moved with care.
Quick stops, excessive force,
and uneven surfaces may cause
the appliance and cart combina-
tion to overturn.
10. Ventilation Slots and openings in the cabinet are provided
for ventilation and to ensure reliable operation of the appliance
and to protect it from overheating, and these openings must not
be blocked or covered. The openings should never be blocked
by placing the appliance on a bed, sofa, rug, or other similar
surface. The appliance should not be placed in a built-in instal-
lation such as a bookcase or rack unless proper ventilation is
provided. There should be free space of at least 20 cm (8 in.)
and an opening behind the appliance.
11. Power Sources The appliance should be operated only from
the type of power source indicated on the marking label. If you
are not sure of the type of power supply to your home, consult
your appliance dealer or local power company.
12. Grounding or Polarization The appliance may be equipped
with a polarized alternating current line plug (a plug having
one blade wider than the other). This plug will fit into the
power outlet only one way. This is a safety feature. If you are
unable to insert the plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit, contact your electrician
to replace your obsolete outlet. Do not defeat the safety pur-
pose of the polarized plug.
13. Power-Cord Protection Power-supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against them, paying particular attention
to cords at plugs, convenience receptacles, and the point where
they exit from the appliance.
14. Lightning For added protection for the appliance during a
lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and discon-
nect the antenna or cable system. This will prevent damage to
the appliance due to lightning and power-line surges.
15. Overloading Do not overload wall outlets, extension cords,
or integral convenience receptacles as this can result in a risk of
fire or electric shock.
16. Object and Liquid Entry Never push objects of any kind
into the appliance through openings as they may touch danger-
ous voltage points or short-out parts that could result in a fire or
electric shock. Never spill liquid of any kind on the appliance.
17. Servicing Do not attempt to service the appliance yourself as
opening or removing covers may expose you to dangerous volt-
age or other hazards. Refer all servicing to qualified service
18. Damage Requiring Service Unplug the appliance form the
wall outlet and refer servicing to qualified service personnel
under the following conditions:
A. When the power-supply cord or plug is damaged,
B. If liquid has been spilled, or objects have fallen into the
C. If the appliance has been exposed to rain or water,
D. If the appliance does not operate normally by following the
operating instructions. Adjust only those controls that are
covered by the operating instructions as an improper
adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the appliance to its normal operation,
E. If the appliance has been dropped or damaged in any way,
F. When the appliance exhibits a distinct change in perfor-
mance this indicates a need for service.
19. Replacement Parts When replacement parts are required, be
sure the service technician has used replacement parts specified
by the manufacturer or have the same characteristics as the
original part. Unauthorized substitutions may result in fire,
electric shock, or other hazards.
20. Safety Check Upon completion of any service or repairs to the
appliance, ask the service technician to perform safety checks to
determine that the appliance is in proper operation condition.
21. Wall or Ceiling Mounting The appliance should be mounted
to a wall or ceiling only as recommended by the manufacturer.
22. Heat The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other appli-
ances (including amplifiers) that produce heat.
23. Liquid Hazards The appliance should not be exposed to
dripping or splashing and no objects filled with liquids, such as
vases should be placed on the appliance.

This activates the auto standby function.
If a constant level signal is not received from the amplifier

automatically enters the standby state. If a constant level
signal is later received from the amplifier (or receiver), the
power is automatically turned back on.

· The auto standby function operates on the existence or
absence of a constant level input signal. If the auto
standby function does not operate properly, try slightly
increasing (or decreasing) the output level of the
amplifier or receiver.
(Note that output levels of some amplifiers and receivers
cannot be adjusted. For more details regarding your
components, refer to the instruction manual supplied
· If noise from peripheral components causes the incorrect
operation of the auto standby function, or if outputting
low volumes (i.e., during the nighttime) causes the auto
standby function to activate, turn off the auto standby

Layout of your speaker system
· Front left/right speakers and center speakers
These three speakers should be placed in front of the
All three speakers should be placed at the same level.
Placement should be such so that the speakers all aim at the
ears of the listener when the listener is listening to music or
watching the screen. The center speakers enhance the sound
effects from the two front speakers and add clarity to
movements in the sound for a much richer sound image.
· Surround left/right speakers
Surround speakers should be placed to the side of the
listener or behind the listener. These speakers produce
sound movements in all directions, create a sound
environment that reflects the background, and create the
sensation of being in the middle of the action.
The subwoofer can be installed anywhere in the room, but in
most situations you will obtain the best results by placing the
subwoofer to the side near a corner of the room. The quality
and level of the bass sounds from the subwoofer will differ
depending on the location where the subwoofer is placed and
the layout of the room, so it is recommended to place the
subwoofer in several locations and find the position that
provides the best results.
Attaching the supplied spacers is recommended for obtaining
the best sound quality. Also, by attaching the provided
spacers, the speakers will not slide easily for a more stable

The speaker bottom and rear are equipped with screw holes so
that you can attach commercially-available stands or
mounting fixtures for a variety of mounting options. (Two M5
screw holes, 60 mm pitch on the bottom and one M5 screw
hole on the rear.)
When attaching an accessory item
to a speaker, be careful of the
length of the screws used. Use
only screws that provide the
required strength with a screw
length between 7 and 12 mm.
