Important safety instructions

•If an outside antenna or cable system is connected to the television, 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 70, provides information with regard 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.

Antenna lead-in wire

•Use No. 10 AWG (5.3 mm2) copper, No. 8 AWG (8.4 mm2) aluminum, No. 17 AWG (1.0 mm2) copper-clad steel or bronze wire, or larger, as a ground wire.

•Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1.22 -1.83 m) apart.

•Mount antenna discharge unit as close as possible to where lead-in enters house.

•Use jumper wire not smaller than No. 6A WG (13.3 mm2) copper, or the equivalent, when a separate antenna-grounding electrode is used. See ANSI/NFPA70.

•An outside antenna system should not be located in the vicinity of overhead 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.

•For added protection for this television during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the power outlet and disconnect it from the antenna or cable system. This prevents damage to the television due to lightning and power line surges.

•Do not overload wall outlets and extension cords, because overloading can cause a fire or electric shock.

•Never push objects of any kind into this television through slots in the case, 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 television.

•Do not attempt to service this television yourself, because opening or removing covers may expose you to dangerous voltages or other hazards. Refer all servicing to qualified service technicians.

•Unplug this television from the wall outlet and refer servicing to qualified service technicians under the following conditions:

•When the power cord or plug is damaged or frayed.

•If liquid has been spilled into the television.

•If the television has been exposed to rain or water.

•If the television does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions, because incorrect adjustment of other controls may result in damage and often requires extensive work by a qualified technician to restore normal operation.

•If the television has been dropped or the case has been damaged.

•When the television exhibits a distinct change in performance.

•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, or other hazards.

•Upon completion of any service or repairs to this television, ask the service technician to perform routine safety checks to determine that the television is safe to operate.

Note to cable television system installer

This reminder is provided to call the cable television system installer’s attention to Section 820 40 of the NEC which provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
