GROUNDING OR POLARIZATION:
• If this product is equipped with a polarized alternating current line plug (a plug
having one blade wider than the other), it will fit into the 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 safety purpose of the polarized
plug.
• If this product is equipped with a three-wire grounding type plug, a plug having
a third (grounding) pin, it will only fit into a grounding type power outlet. This is a
safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the
grounding type plug.
POWER-CORD PROTECTION: Power-supply cords should be routed so that they
are not likely to be walked on or pinched by items placed upon or against them,
paying particular attention to cords at plugs, convenience receptacles, and the
point where they exit from the product.
OUTDOOR ANTENNA GROUNDING: If an outside antenna or cable system is con-
nected 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 B.
LIGHTENING: For added protection for this product during a lightening 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 lightening and power-line surges.
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,
extreme care should be taken to keep from touching such power lines or circuits
as contact with them might be fatal.
