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 pro duct is equipped wit h a th ree-w ire
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, lo cation of antenna-discharge unit,
co nn ecti on t o g roun ding e lec tr odes , a nd
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 outl ets,

extension cords, or integral convenience receptacles
as this can result in a risk of fire or electric shock.
