External Television Antenna Grounding 
If an outside antenna or cable system is connected to the 
product, be sure the antenna or cable system is electrically 
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 electrical grounding of the 
mast and supporting structure, grounding of the lead-in wire 
to an antenna-discharge unit, size of grounding conductors, 
location of antenna-discharge unit, connection to grounding 
electrodes, and requirements for the grounding electrode. 
Lightning Protection 
For added protection of any product during a lightning 
storm, or when it is left unattended and unused for long 
periods of time, unplug the product from the wall outlet and 
disconnect the antenna or cable system. This will prevent 
damage to the product from lightning and power line 
surges.
