16-2 Note to CATV system installer: (Only for the television set with CATV reception) This
reminder is provided to call the CATV system installer's attention to Article 820-40 of the NEC that
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.
17 An outside antenna system should not be located in the vicinity of overhead power lines or other
electrical lights 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.
18 For added protection for this television set 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. This
will prevent damage due to lightning and power-line surges.
