PROTECTION AND LOCATION OF YOUR SET
12 Do not use this television set near water, for example, near a bathtub, washbowl, kitchen sink, or laundry tub,
in a wet basement, or near a swimming pool, etc.
• Never expose the set to rain or water. If the set has been exposed to rain or water, unplug the set from the wall
outlet and refer servicing personnel.

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.

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

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.
