8. Accessories. Do not place this product on
an unstable cart, stand, tripod, bracket or
table. The product may fall, causing serious
injury to a child or adult, and serious
damage to the product. Use only with a cart,
stand, tripod, bracket or table recommended
by the manufacturer, or sold with the product.
Any mounting of the product should follow
the manufacturer’s instructions, and should
use a mounting accessory recommended by
the manufacturer.
9. A Product and Cart
Combination Should Be
Moved with Care. Quick
stops, excessive force and
uneven surfaces may cause
the product and cart combination to
overturn.
10. Ventilation. Slots and openings in the
cabinet are provided for ventilation and to
ensure reliable operation of the product and
to protect it from overheating, and these
openings must not be blocked or covered.
The openings should never be blocked by
placing the product on a bed, sofa, rug or
other similar surface. This product should not
be placed in a built-in installation, such as a
bookcase or rack, unless proper ventilation is
provided or the manufacturer’s instructions
have been adhered to.
11. Power Sources. This product 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 product dealer or local
power company. For products intended to
operate from battery power, or other sources,
refer to the operating instructions.
12. Grounding or Polarization. This product
may be equipped with a polarized alternatingcurrent-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
purpose 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 product.
14. Nonuse Periods. The power cord of the
product should be unplugged from the outlet
when left unused for long periods of time.
15. Outdoor Antenna Grounding. If an
outside antenna or cable system is connected
to the product, be sure the antenna or cable
system is grounded so as to provide some
protection against voltage surges and built-up
static charges. Article 810 of the National
Electrical Code, ANSI/NFPA 70, provides
information with regard to proper grounding
of the mast and supporting structure,
grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors,
location of antenna-discharge unit,
connection to grounding electrodes, and
requirements for the grounding electrode. See
Figure 1.
16. Lightning. For added protection for this
product during a lightning storm, or when
it is left unattended and unused for long
periods of time, unplug it from the wall outlet
and disconnect the antenna or cable system.
This will prevent damage to the product due
to lightning and power-line surges.
17. Power Lines. An outside antenna system
should not be located in the vicinity of
overhead power lines or other electric light or
power circuits, or where it can fall into such
power lines or circuits. When installing an
outside antenna system, extreme care should
be taken to keep from touching such power
lines or circuits, as contact with them might
be fatal.
18. Overloading. Do not overload wall
outlets, extension cords, or integral
convenience receptacles, as this can result in
a risk of fire or electric shock.
19. Object and Liquid Entry. Never push
objects of any kind into this product through
openings, as they may touch dangerous
voltage points or short-out parts that could
result in a fire or electric shock. Never spill
liquid of any kind on the product.
20. Servicing. Do not attempt to service this
product yourself, as opening or removing
covers may expose you to dangerous voltage
or other hazards. Refer all servicing to
qualified service personnel.
21. Damage Requiring Service. Unplug this
product from the wall outlet and refer
servicing to qualified service personnel
under the following conditions:
a. The power-supply cord or the plug has
been damaged; or
b. Objects have fallen onto, or liquid has
been spilled into, the product; or
c. The product has been exposed to rain or
water; or
d. The product does not operate normally
when 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
product to its normal operation; or
e. The product has been dropped or
damaged in any way; or
f. The product exhibits a distinct
change in performance; this indicates a
need for service.
22. Replacement Parts. When replacement
parts are required, be sure the service
technician has used replacement parts
specified by the manufacturer or that have the
same characteristics as the original part.
Unauthorized substitutions may result in fire,
electric shock or other hazards.
23. Safety Check. Upon completion of any
service or repairs to this product, ask the
service technician to perform safety checks
to determine that the product is in proper
operating condition.
24. Wall or Ceiling Mounting. The product
should be mounted to a wall or ceiling only as
recommended by the manufacturer.

To connect your speakers,
press down on the quickrelease tab, which opens
the terminal for the speaker
wire, and put the bare end
of the wire in straight.
Release the tab and give
the speaker wire a gentle
tug. If it’s in properly, it
won’t “give” at all. If it
slides, repeat the procedure.
Use the shortest wire for the
CENTER speaker, the two
medium-length wires for the
FRONT speakers and the
long wires for the REAR
speakers.
Always insert the REDcoated wire into the RED
terminals and the BLACKcoated wire into the
BLACK terminals on each of
your speakers and on the
appropriate terminal on the
back of the Main Unit.
