Outdoor Antenna Grounding - 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, 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.

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.
