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-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. (Fig. A) 14.Lightning-For added protection for this TVNCR receiver during 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 TVNCR 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 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. 16.Overloading-Do not overload wall outlets and extension 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 TVNCR through openings as they may touch dangerous voltage points or short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the TVNCR. 18Servicing-Do not attempt to service this TVNCR yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel. 19.Damage Requiring Service-Unplug this TVNCR from the wall outlet and refer servicing to qualified service personnel under the following conditions: a. When the power-supply cord or plug is damaged or frayed. b. If liquid has been spilled, or objects have fallen into the TVNCR. c. If the TVNCR has been exposed to rain or water. d. If the TVNCR does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions, as improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the TVNCR to its normal operation. e. If the TVNCR has been dropped or damaged in any way. f. When the TVNCR exhibits a distinct change in performance-this indicates a need for service. 20.Replacement Parts-When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, injury to persons or other hazards. 21.Safety Check-Upon completion of any service or repairs to this TVNCR, ask the service technician to perform routine safety checks to determine that the TVNCR is in proper operating condition. 22.Heat-This TVNCR product should be situated away from heat sources such as radiators, heat registers, stoves, or other products (including amplifiers) that produce heat. - 3 - EN 5L01
