13.OUTDOOR ANTENNA GROUNDING-If an outside anten- na or cable system is connected to the TV, be sure the antenna or cable 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 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-dis- charge unit, connection to grounding electrodes, and requirements for the grounding electrode. (Fig. A)
14.LIGHTNING-For added protection for this TV receiver dur- ing 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 TV due to lightning and power- line surges.
15.POWER LINES-An outside antenna system should not be located in the vicinity of overhead power lines or other electric light of 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 touch- ing such power lines or circuits as contact with them might be fatal.
16.OVERLOADING-Do not overload wall outlets and exten- sion cords as this can result in a risk of fire or electric shock.
17.OBJECT AND LIQUID ENTRY-Never push objects of any kind into this TV through openings as they may touch dan- gerous voltage points or short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the TV.
18.SERVICING-Do not attempt to service this TV yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
