ANTENNA INSTALLATION SAFETY
Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the LED TV, be sure the 
antenna or cable system is grounded to prevent voltage surges and built-up static 
charges. Article 810 of the National Electrical Code, ANS/NFPA 70, provides 
information on 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.
Lightning
Power lines
For added protection for the LED TV 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. DO NOT disconnect the antenna or the power cord during 
a heavy storm—lightning may strike while you are holding the 
cable cord, causing serious injury. Turn off the LED TV 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.
