Power Source Warning

A label on this product indicates the correct power source for this product. Operate this product only from an electrical

outlet with the voltage and frequency indicated on the product label. If you are uncertain of the type of power supply to

your home or business, consult your service provider or your local power company.

Ground the Product

WARNING:

Avoid electric shock and Þ re hazard! Do not defeat the safety purpose of the polarized or grounding-type

plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades

and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug

does not Þ t into your outlet, consult an electrician for replacement of the obsolete outlet.

If this product connects to coaxial cable wiring, be sure the cable system is grounded (earthed). Grounding provides

some protection against voltage surges and built-up static charges.

Outdoor Grounding System

If this product connects to an outdoor antenna or cable system, be sure the antenna or cable system is grounded

(earthed). This provides some protection against voltage surges and built-up static charges.

Article 810 of the National Electric Code (NEC) ANSI/NFPA No. 70-1990, provides the following information:

• Grounding of the mast and supporting structure

• Grounding the lead-in wire to an antenna discharge unit

• Size of the grounding conductors

• Location of the antenna-discharge unit

• Connection to grounding electrodes

• Requirements for the grounding electrodes (see the following antenna grounding diagram as recommended by

NEC ANSI/NFPA 70)

WARNING:

Avoid electric shock and Þ re hazard! Do not locate an outside antenna system in the vicinity of overhead

power lines or power circuits. Touching power lines or circuits might be fatal.
