16. Servicing - The user should not attempt to service the product beyond that
described in the operating instruction. All servicing should be referred to qualified
service personnel.
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 power lines or circuits as
contact with them might be fatal.
18. 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. Section 810 of the National
Electrical Code ANSI/NEFA 70 provides information with respect to proper
grounding of the mast and supporting structure, grounding conductress, location
of antenna-discharge unit, size of grounding electrodes, and requirements for
the grounding electrode (see figure).
19. Lightning - For added protection for this product 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 or cable system. This will prevent
damage to the product due to lightning and power-line surges.
20. 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 operation condition.
21. Overloading-Do not overload wall outlets, extension cords, or integral
convenience receptacles as this can result in a risk of fir or electric shock.
