14 Avoid dusty places, since accumulated dust inside the chassis may cause failure of
the set when high humidity persists.
15 The set has slots, or openings in the cabinet for ventilation purposes, to provide
reliable operation of the receiver, and to protect from overheating. These openings must
not be blocked or covered.
• Never cover the slots or openings with cloth or other material.
• Never block the bottom ventilation slots of the set by placing it on a bed, sofa, rug, etc.
• Never place the set near or over a radiator or heat register.
• Never place the set in a "built-in" enclosure, unless proper ventilation provided.
PROTECTION AND LOCATION OF YOUR SET
16-1 If an outside antenna is connected to the television set, be sure the antenna
system is protected against voltage surges and built up static charges, Section 810 of
the National Electrical Code, NFPA No. 70-1975, 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 electrode, and requirements for the grounding electrode.
EXAMPLE OF ANTENNA GROUNDING
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
