Safety Precautions
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 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 A.
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 damage
to the product due to lightning 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.
OVERLOADING — Do not overload wall outlets,
extension cords, or integral convenience
receptacles as this can result in a risk of fire or
electric shock.
