Important Safeguards
Grounding or Polarization – This video product is
equipped with a polarized alternating-current (AC)
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 unable
to insert the plug fully into the outlet, try reversing
the plug. If the plug should still fail to fit, contact
your electrician to replace your obsolete outlet. Do
not defeat the satety purpose of the polarized plug.
Overloading – Do not overload wall outlets
extension cords as this can result in a risk of fire or
electric shock.
Outdoor Antenna Grounding – If an outside
antenna or cable system is connected to the video
product, be sure the antenna or cable system is
grounded so as to provide some protection against
voltage surges and built-up static charges. Section
810 of the National Electrical Code, ANSI/NFPA
No. 70-1984, provides information with respect 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 the
National Electrical Code example below.
