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 Appliances 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 Appliance by placing it on
a bed, sofa, rug, etc.
– Never place an Appliance in a “built-in”
enclosure unless proper ventilation is
provided.
– Never cover the openings with a cloth
or other material.
– Never place the Appliance near or over
a radiator or heat register.
9 To avoid personal injury:
– Do not place an Appliance on a sloping
shelf unless properly secured.
– Use only a cart or stand recommended
by the Appliance manufacturer.
– Do not try to roll a cart with small
casters across thresholds or deep pile
carpets.
– Wall or shelf mounting should follow the
manufacturer’s instructions, and should
use a mounting kit approved by the
manufacturer.
