voltage points or short out parts that could result in fire or electric shock. Never spill or spray any type of liquid on the product.

17.OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to the prod- uct, 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 Electric Code, ANSI/NFPA 70, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna dis- charge product, size of grounding conductors, location of antenna discharge product, connec- tion to grounding electrodes and requirements for grounding electrodes.
