Use proper
power
sources-
Plug the product into
a proper power source, as described
in
the operating
instructions or as marked on the product.
19.
Avoid
power
lines-
Use extreme care when
installing an outside antenna system
to
keep from
touching power lines or circuits, as contact with
them may be fatal. Do not install external antennas
near overhead power lines or other electric light or
power circuits, nor where
an
antenna can fall into
such circuits or power lines.
20.
Ground all outdoor
antennas-
If
an
external
antenna or cable system is connected
to
this
product, be sure the antenna or cable system is
grounded. This will provide some protection against
voltage surges and built-up static charges.
