• Ventilation–Slots and openings in the
cabinet and the back or bottom are provided
for ventilation, to ensure reliable operation of
your home theater system, and to protect it
from overheating. Do not block openings. Do
not place your home theater system on a
bed, sofa, rug, or other similar surface. Your
home theater system should never be placed
near or over a radiator or heat register. Do
not place your home theater system in a
built-in installation such as a bookcase or
rack unless correct ventilation is provided or
the manufacturer’s instructions have been
adhered to.
• Power sources–Use only 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 home theater
system dealer or local power company.
• Grounding or polarization–Your home
theater system is 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 purpose of
the polarized plug.
• Power-cord protection–Route power-supply
cords 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 your home
theater system.
• Outdoor antenna grounding–If an outside
antenna or cable system is connected to your
home theater system, make sure that the
antenna or cable system is grounded to
provide some protection against voltage
surges and built-up static charges. Article
810 of the National Electrical Code, ANSI/
NFPA No. 70, provides information with
respect to correct 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.
• Lightning–For added protection for your
home theater system 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 your home theater system due to
lightning and power-line surges.
• 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, do not touch power
lines or circuits because contact with them
might be fatal.
• Overloading–Do not overload wall outlets
and extension cords because this can result
in a risk of fire or electric shock.
• Object and liquid entry–Never push objects
of any kind into your home theater system
through openings because 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 your home
theater system.
• Servicing–Do not attempt to service your
home theater system yourself because
opening or removing covers may expose you
to dangerous voltage or other hazards. Refer
all servicing to qualified service personnel.
• Damage requiring service–Unplug your
home theater system from the wall outlet and
refer servicing to qualified service personnel
under the following conditions:
•
When the power supply cord or plug is
damaged or frayed.
• If liquid has been spilled, or objects have
fallen into your home theater system.
• If your home theater system has been
exposed to rain or water.
• If your home theater system does not
operate normally by following the
operating instructions. Adjust only those
controls that are covered by the operating
instructions, because incorrect
adjustment of other controls may result in
damage and often requires extensive
work by a qualified technician to restore
your receiver to its normal operation.
• If your home theater system has been
dropped or damaged in any way.
• When your home theater system exhibits
a distinct change in performance, this
indicates a need for service.
