An outside antenna system should not be located
in the vicinity
of overhead
power
lines or other
electrical
lights 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.
For added protection
for this television
set du ring
a lightning
storm, or when it is left unattended
and
unused for long periods
of time, unplug it from the
wall outlet and disconnect
the antenna.
This will
prevent
damage
due to lightning
and power-line
surges.
