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 Þre 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.  
WARNING:  
Avoid electric shock and Þre 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 Þt into  
your outlet, consult an electrician for  
replacement of the obsolete outlet.  
Protect the Product from Lightning  
For added protection, unplug this apparatus  
during lightning storms or when unused for long  
periods of time. In addition to disconnecting the  
AC power from the wall outlet, disconnect the

be sure the cable system is grounded (earthed).  
Grounding provides some protection against  
voltage surges and built-up static charges.  
Verify the Power Source from the  
On/Off Power Light  
When the on/off power light is not illuminated,  
the apparatus may still be connected to the  
power source. The light goes out when the  
apparatus is turned off, regardless of whether  
it is still plugged into an AC power source.  
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.  
Eliminate AC Mains Overloads  
Article 810 of the National Electric Code (NEC)  
ANSI/NFPA No. 70-1990, provides the following  
information:  
WARNING:  
Avoid electric shock and Þre hazard!  
Do not overload AC mains, outlets,  
extension cords, or integral convenience  
receptacles. For products that require  
battery power or other power sources  
to operate them, refer to the operating  
instructions for those products.  
• Grounding of the mast and supporting  
structure  
• Grounding the lead-in wire to an antenna  
discharge unit  
• Size of the grounding conductors
