IMPORTANT SAFETY PRECAUTIONS (Continued)
■ 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.
■ An outside antenna system should not be located in the vi-
cinity 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.

■ 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 dis-
connect the antenna. This will prevent damage to the equip-
ment due to lightning and power-line surges.
