14. 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 (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, location of antenna-dis-
charge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
15. Lightning
For added protection for this product (receiver) during a light-
ning 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 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.

Do not overload wall outlets and extension cords as this can
result in a risk of fire or electric shock.
