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, location of antenna-discharge unit, connection to grounding elec-
trodes, and requirements for the grounding electrode.

•
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.
•
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.
