12. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the TV 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 informa-
tion with regard 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, connect on to grounding electrodes, and requirements for the grounding electrode.

10. Power-Cord Protection
Power-supply cords should be routed so that they are not likely to be walked on or pinched by
items placed upon or against them, paying particular attention to cords at plugs,convenience
receptacles, and the point where they exit from the TV.
11. Lightning
For added protection for the TV 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 TV from lightning and power-line surges.
13. 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 on to 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.
14. Overloading
Do not overload wall outlets and extension cords as this can result in a risk of fire or electric
shock.
