Danger:

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 product
due to lightning and power line surges.
• 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.
