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, ANSI/
NFPA 70, provides information with regard to proper grounding of the
mast and supporting structure, grounding of!the lead-in wire to an an-
tenna discharge unit, size of grounding conductors, location of antenna-
discharge unit, connection to grounding electrodes, and requirements
for the grounding electrode.
16
Lightning - For added protection for this product 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 the product 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, extreme care should
be
taken to keep from
touching such power lines or circuits as contact with them might be
fatal.

Overloading -
Do
not overload wall outlets, extension cords,
or
integral
convenience receptacles
as
this
can
result
in
a risk
of
fire
or
electric shock.
