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 fi 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 fit 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.
