Notice to Installers
The servicing instructions in this notice are for use by qualiÞ 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 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.
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.
WARNING
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.

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.
• 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 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.
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
