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.
The AC inlet on the unit must remain accessible and operable at all times.
Ground the Product
WARNING: Avoid electric shock and fi re hazard! Do not defeat the safety purpose of the polarized

provided plug does not fi 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 fi 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.
Notice to Installers
The servicing instructions in this notice are for use by qualifi ed service personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained
