ANTENNA INSTALLATION
INSTRUCTIONS
1. 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.
2. 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.
3. 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.

SAFETY INSTRUCTIONS
Electrical energy can perform many useful func-
tions. But improper use can result in potential
electrical shock or fire hazards. This product has
been engineered and manufactured to assure your
personal safety. In order not to defeat the built-in
safeguards, observe the following basic rules for its
installation, use and servicing.
ATTENTION:
Follow and obey all warnings and instructions
marked on your product and its operating instruc-
tions. For your safety, please read all the safety and
operating instructions before you operate this
product and keep this manual for future reference.
INSTALLATION
1. Grounding or Polarization
(A) Your 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 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.
(B) Your product may be equipped with a 3-wire
grounding-type plug, a plug having a third
(grounding) pin. This plug 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.
2. Power Sources
Operate your product only from the type of power
source indicated on the marking label. If you are not
sure of the type of power supply to your home, consult
your product dealer or local power company. If your
product is intended to operate from battery power, or
other sources, refer to the operating instructions.
3. Overloading
Do not overload wall outlets, extension cords, or
integral convenience receptacles as this can result in a
risk of fire or electric shock.
4. 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.
