12. 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.
13. Overloading
Do not overload wall outlets, extension cords or integral convenience receptacles as this can result in a risk
of fire or electric shock.
14. Object and Liquid Entry
Never push objects of any kind into this product through openings as they may touch dangerous voltage points or
short-out parts that could result in fire or electric shock. Never spill liquid of any kind on or into the product.
15. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so
as to provide some protection against voltage surges and built-up static charges.
Section 810 of the National Electric Code, ANSI/NFPA No. 70, 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 electrodes,
and requirements for the grounding electrode.
16. Servicing
Do not attempt to service this product yourself as opening or removing covers may
expose you to dangerous voltage or other hazards. Refer all servicing to qualified
service personnel.
