ANTENNA INSTALLATION INSTRUCTIONS
1. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the product be sure the antenna or cable system is
grounded so as to provide some protection against voltage surges and built-up static charges, Article 810 of the
National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an antenna discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.
2. Lightning
For added protection for this product 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 product due to lightning and power-line surges. Do not disconnect the antenna or the power cord
during a heavy storm lighting may strike while you are holding the cable cord, causing serious injury; turn off
you LCD and wait for the wether to improve.
3. Power Lines
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.
