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.

IMPORTANT PRODUCT

SAFETY INSTRUCTIONS

Electrical energy can perform many useful functions. 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 instructions. 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.
