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 .

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.

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
set by placing it on a bed, sofa, rug, etc.
— Never place a TV set in a “built-in” enclosure unless
proper ventilation is provided.
— Never cover the openings with a cloth or other material.
— Never place the TV set near or over a radiator or heat re g i s t e r.

To avoid personal injury:
— Do not place a TV set on a sloping shelf unless properly secure d .
— Use only a cart or stand recommended by the TV s e t

— Do not try to roll a cart with small casters across thresh-
olds or deep pile carpets.
— Wall or shelf mounting should follow the manufacturer’s
instructions, and should use a mounting kit approved by
the manufacturer.
USE
10
Caution children about dropping or pushing objects into the TV set
t h rough cabinet openings. Some internal parts carry hazard o u s
voltages and contact can result in a fire or electrical shock.
11
Unplug the TV set from the wall outlet before cleaning. Do
not use liquid or an aerosol cleaner.
12
Never add accessories to a TV set that has not been designed for
this purpose. Such additions may result in a hazard .
13
For added protection of the TV set during a lightning storm or
when the TV set is to be left unattended for an extended peri-
od of time, unplug it from the wall outlet and disconnect the
antenna. This will prevent damage to product due to lightning
s t o rms or power line surg e s .

other hazards. Refer all servicing to qualified service person-
n e l .
17
