Important Safeguards (cont.)
14. 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.
15. Overloading
Do not overload wall outlets and extension cords
as this can result in a risk of fire or electric shock.
16. Object and Liquid Entry
Never push objects of any kind into this TV
receiver 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 TV receiver.
17. Outdoor Antenna Grounding
If an outside antenna or cable system is connected
to the TV receiver, be sure the antenna or cable
system is grounded so as to provide some protec-
tion against voltage surges and built-up static
charges.
Section 810 of the National Electrical Code, ANSI/
NFPA No. 70-1984, provides information with
respect 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 dis-
charge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
