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.

 

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 your LCD Display and wait for the weather 

to improve.

 

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.
