15. Outdoor Antenna Grounding - If an outside antenna is
connected to the receiver, 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 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 electrodes, and requirements
for the grounding electrode.

surges.
17. 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.

22. Replacement Parts - When replacement parts are required, be sure the service technician has used replacement parts
specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result
in fire, electric shock, or other hazards.
23. Safety Check - Upon completion of any service or repairs to this product, ask the service technician to perform safety
checks to determine that the product is in proper operating condition.
