13.Outdoor Antenna grounding-If an outside antenna or
cable system is connected to this 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 No. 70, 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-discharge
unit, connection to grounding electrodes, and requirements
for the grounding electrode. (Fig. A)
14.Lightning-For added protection for this product receiver
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 this product due to lightning and power-
line surges.
15.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.
16.Overloading-Do not overload wall outlets and extension
cords as this can result in a risk of fire or electric shock.
