Note to CATV System Installer
This reminder is provided to direct 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.
Secure Ventilation
Slots and openings in the cabinet and the back or bottom are provided for ventilation, and to ensure reliable operation of the
LCD TV and to protect it from overheating. These openings must not be blocked or covered. There should be at least 4 inches
(10 cm) of space around the TV. The openings should never be blocked by placing the LCD TV on a bed, sofa, rug or other similar
surface. This LCD TV should not be placed in a built-in installation such as a bookcase unless proper ventilation is provided.
