IMPORTANT SAFEGUARDS
14 Avoid dusty places. Accumulated dust inside the chassis may cause failure of the television when high
humidity persists.
15 The television has slots or openings in the cabinet for ventilation purposes which provide reliable operation of
the receiver and protect the television 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 television by placing it on a bed, sofa, rug, etc.
• Never place the television near or over a radiator or heat generator.
• Never place the television in a built-in enclosure, unless proper ventilation is 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.
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.
