•Use No. 10AWG (5.3 mm2) copper, No. 8AWG (8.4 mm2) aluminum,

No. 17AWG (1.0 mm2) copper-clad steel or bronze wire, or larger, as a ground wire.

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

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

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

•For added protection for your 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 your television due to lightning and power line surges.

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

•Unplug your television from the power 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 your television.

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

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

•When your television exhibits a distinct change in performance.

•When replacement parts are required, make sure that the service technician uses 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 your television, ask the service technician to perform routine safety checks to determine that your 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.
