IMPORTANT SAFETY PRECAUTIONS (Continued)

I If an outside antenna is connected to the television equipment, be sure the antenna system is

grounded so as to provide some protection against voltage surges and built-up static charges.

Section 810 of the National Electrical Code 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, Iocation of antenna-discharge unit, connection to grounding elec-

trodes, and requirements for the grounding electrode.

NEC—NATIONAL ELECTRICAL CODE

I For added protection for this television equipment 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. This will prevent damage to the

equipment due to lightning and power-line surges.

I 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.
