you are not sure of the type of power supply to your home,
consult your product dealer or local power company. For
products intended to operate from battery power, or other
sources, refer to the operating instructions.
12. Grounding or Polarization – This product may be equipped
with a polarized alternating-current line plug (a plug having
one blade wider than the other).This plug will fit into the
power outlet only one way.This is a safety feature. If you are

14. 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, size of grounding conductors,
location of antenna-discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.
See figure at right.
15. 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

surges.
16. 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, take extreme care to keep it from touching such
power lines or circuits; contact with them might be fatal.
