Outdoor antenna
grounding

If an outside antenna or cable system is connected
to the equipment, be sure the antenna or cable
system is grounded as to provide some protection
against voltage surges and built-up static charges.

Lightning

For added protection for this equipment during 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 or cable
system. This will prevent damage to the video

Power lines

An outside antenna system should not be located
in the vicinity of overhead power lines 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 may be fatal.
