Power Source Warning
A label on this product indicates the correct power source for this product. Operate this product only from an elec-
trical 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
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 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.
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 Power/Mains Overloads
WARNING: Avoid electric shock and fi re hazard! Do not overload AC power/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.
Prevent Power Cord Damage
Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the
point where the cord exits from the apparatus.

• Do not install this apparatus in an enclosure, such as a bookcase or rack, unless the installation provides proper
ventilation.
• Do not place entertainment devices (such as VCRs or DVDs), lamps, books, vases with liquids, or other objects
on top of this product.
Operating Environment
The set-top is designed for operation indoors with a temperature range from 32° to 104° F (0° to 40°C). Each set-
top should have adequate spacing on all sides so that the cooling air vents on the chassis are not blocked.
Protect from Exposure to Moisture and Foreign Objects
Do not use this apparatus near water.
WARNING: Avoid electric shock and fi re hazard! Do not expose this product to liquids, rain, or
moisture.
WARNING: Avoid electric shock and fi re hazard! Unplug this product before cleaning. Clean
only with a dry cloth. Do not use a liquid cleaner or an aerosol cleaner. Do not use a magnetic/static
cleaning device (dust remover) to clean this product.
WARNING: Avoid electric shock and fi re hazard! Never push objects through the openings in
this product. Foreign objects can cause electrical shorts that can result in electric shock or fi re.
Accessories Warning
WARNING: Avoid electric shock and fi re hazard! Only use attachments/accessories specifi ed
by your service provider or the manufacturer.
Service Warnings
WARNING: Avoid electric shock! Do not open the cover of this product. Opening or removing
the cover may expose you to dangerous voltages. If you open the cover, your warranty will be void. This
product contains no user-serviceable parts. Refer all servicing to qualifi ed service personnel.
Servicing is required when the apparatus has been damaged in any way, such as a power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or
