IMPORTANT SAFEGUARDS
1. All the safety and operating instructions should
be read before the appliance is operated.
2. The safety and operating instructions should be
retained for future reference.
3. All warnings on the appliance and in the oper-
ating instructions should be adhered to.
4. All operating and use instructions should be
followed.
5. Unplug this video or audio product from the wall
outlet before cleaning. Do not use liquid cleaners
or aerosol cleaners. Use a damp cloth for cleaning.
6. Do not use attachments not recommended by
the video product manufacturer as they may cause
hazards.
7. Do not use this video product 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. If slots, holes and openings are located in the
housing, they are provided for ventilation and to
ensure reliable operation of the video product and
to protect it from overheating. These openings
should never be covered. The openings should
never be blocked by placing the video product on
a bed, sofa, rug, or other similar surface. This
video product should never be placed near or over
a radiator or heat register. This video 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.
9. This video product should be operated only from
the type of power source indicated in electrical
rating printed on the appliance or power supply.
10A. If the appliance 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 an electrician to replace your
obsolete outlet. Do not defeat the safety purpose
of the polarized plug.
10B. If the appliance is equipped with a 3-wire
grounding-type plug, a plug having a third (ground-
ing) pin, this plug will only fit into a grounding-type
power outlet. This is a safety feature. If you are
unable to insert the plug into the outlet, contact an
electrician to replace your obsolete outlet. Do not
defeat the purpose of the grounding-type plug.
11. Power-supply cord should be routed so that it
is not likely to be walked on or pinched by items
placed upon or against it, paying particular
NEC - NATIONAL ELECTRICAL CODE
13. 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 install-
ing 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.
14. For added protection for this video product
during a lightning storm, or when it is left unat-
tended and unused for long periods of time, un-
plug it from the wall outlet and disconnect the
antenna or cable system.
15. Do not overload wall outlets and extension
cords as this can result in a risk of fire or electric
shock.
16. Never push objects of any kind into this video
product through openings as they may touch dan-
gerous voltage points or short-out parts that could
result in a fire or electric shock. Never spill liquid of
any kind on the video product.
