6 If an outside antenna is connected to the TV set, be sure the
antenna system is grounded so as to provide some pro t e c t i o n
against voltage surges and built-up static charges. Section 810
of the National Electrical Code provides information with re s p e c t
to proper grounding of the mast and supporting stru c t u re ,
g rounding of the lead-in wire to an antenna discharge unit, size
of grounding conductors, location of antenna discharge unit,
connection re q u i rements for the grounding electro d e .
7 An outside antenna system should not be located in the
vicinity of overhead power lines or other electric light 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.
8 TV sets are provided with ventilation openings in the cabinet
to allow heat generated during operation to be released.
Therefore:
— Never block the bottom ventilation slots of a portable TV

instructions, and should use a mounting kit approved by
the manufacturer.
