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.

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.
