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
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 register.
9 To avoid personal injury:
-- Do not place a TVset on a sloping shelf unless properly secured.
-- Use only a cart or stand recommended
by the TV set
manufacturer.
-- 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 oL_ectsinto the TV set
through cabinet openings. Some internal parts carry hazardous
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.
For added protection of the TV set during a lightning storm or
when the TV set is to be left unattended for an extended period
of time, unplug it from the wall outlet and disconnect the
antenna. This will prevent damage to product due to lightning
storms or power line surges.
A TV set and cart combination should be moved with care.
Quick stops, excessive force, and uneven surfaces may cause
the TV set and cart combination to overturn.

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.
