14. Outdoor Antenna Grounding
NEC - National Electrical Code
Ground Clamp
Electric Service
Equipment
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 (U.S.A.),
ANSI/ NFPA 70 provides information with regard to
proper grounding of the mast and supporting struc-
ture, grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors, loca-
tion of antenna-discharge unit, connection to
grounding electrodes, and requirements for the
grounding electrode.
15. Lightning
For added protection for this product (receiver) dur-
ing 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.
16. Power Lines
An outside antenna system should not be located in
the vicinity of overhead power lines or other elec-
tric light or power circuits, or where it can fall into
such power lines or circuits. When installing an out-
side antenna system, extreme care should be taken
to keep from touching such power lines or circuits
as contact with them might be fatal.
17. Overloading
Do not overload wall outlets and extension cords as
this can result in a risk of fire or electric shock.
18. 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.
