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 fire
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.
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 fire
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.
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 signal inputs.
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.
Eliminate AC Mains Overloads
WARNING: Avoid electric shock and fire
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.
