Notice to Installers
The servicing instructions in this notice are for use by qualiÞ ed service personnel only. To reduce risk of electric shock, do not perform any servicing other than that contained in
the operating instructions, unless you are qualiÞ 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.
IMPORTANT SAFETY 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
Avoid electric shock and Þ 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 Þ 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)
Avoid electric shock and Þ 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.
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.

goes out when the apparatus is turned off, regardless of whether it is still plugged into an AC power source.
Eliminate AC Mains Overloads
Avoid electric shock and Þ 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.
