13.Outdoor AntennaGrounding - Ifan 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
ElectricalCode, 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-dis
charge unit, size of grounding conductors,location of antenna-
discharge unit, connection to grounding electrodes and
requirements for the grounding electrode. See Figure 1.
14.Non-use Periods - The power cord of the appliance should be
unplugged from the outletwhen left unused for a long period
