13.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 lead-in wire to an antenna-dis charge unit, size of grounding conductors,location of antenna­discharge 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 outlet when left unused for a long period of time.
15.Object and Liquid Entry - Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.
