IMPORTANT SAFETY PRECAUTIONS

• Outdoor Antenna Grounding — 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.

Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information 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, Iocation of antenna-discharge unit, connection to grounding electrodes, and requirements for the

grounding electrode.

• Lighting — 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.

• 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.
