Notice for 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 in the operating instructions, unless you are qualifi ed to do so.
Note to System Installer
For this apparatus, the coaxial cable shield/screen shall be
grounded as close as practical to the point of entry of the cable
into the building. For products sold in the US and Canada, this
reminder is provided to call the system installer's attention to
Article 820-93 and Article 820-100 of the NEC (or Canadian
Electrical Code Part 1), which provides guidelines for proper
grounding of the coaxial cable shield.
This symbol is intended to alert you that uninsulated voltage
within this product may have sufficient magnitude to cause
electric shock.Therefore, it is dangerous to make any kind of
contact with any inside part of this product.
Ce symbole a pour but d’alerter toute personne qu’un contact
avec une pièce interne de ce produit, sous tension et non isolée,
pourrait être suffisant pour provoquer un choc électrique. Il est
donc dangereux d’être en contact avec toute pièce interne de
ce produit.
CAUTION: To reduce the risk of electric shock, do not
remove cover (or back). No user-serviceable parts
inside. Refer servicing to qualified service personnel.
TO PREVENT FIRE OR ELECTRIC SHOCK, DO NOT
EXPOSE THIS UNIT TO RAIN OR MOISTURE.
This symbol is intended to alert you of the presence
of important operating and maintenance (servicing)
instructions in the literature accompanying this product.
Ce symbole a pour but de vous avertir qu’une
documentation importante sur le fonctionnement et
l’entretien accompagne ce produit.

IMPORTANT SAFETY INSTRUCTIONS
Read These Instructions
Keep These Instructions
Heed All Warnings
Follow All Instructions
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 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.
T13508
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 may go
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 fi re
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.
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.
Provide Ventilation and Select a Location
• Remove all packaging material before applying power to the
product.
• Do not block any ventilation openings. Install in accordance
with the manufacturer’s instructions.
• Do not place this apparatus on a bed, sofa, rug, or similar
surface.
• Do not place this apparatus on an unstable surface.
• Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifi ers)
that produce heat.
• 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.
