The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of un-insulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude
A
to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE
TO RAIN OR MOISTURE. DO NOT OPEN THE CABINET.
REFER SERVICING TO QUALIFIED PERSONNEL ONLY.
CAUTION: TO PREVENT ELECTRIC SHOCK DO NOT USE THIS (POLARIZED) PLUG WITH AN EXTENSION
CORD RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED
TO PREVENT BLADE EXPOSURE.
ATTENCION: POUR PREVENIR LES CHOCS ELECTRIQUES, NE PAS UTILISER CETTE FICHE POLARISEE AVEC
UN PROLONGATEUR, UNE PRISE DE COURANT OU UNE AUTRE SORTIE DE COURANT, SAUF SI
LES LAMES PEUVENT ETRE INSEREES A FOND SANS EN LAISSER AUCUNE PARTIE A DECOUVERT.

covered. Openings should never be blocked by placing the product on
a bed, sofa, rug, or other similar surface.
10. Grounding or Polarization: This video product is equipped with
either a three prong plug for 110 VAC use or a two prong flat blade
220 volt type plug. Each type is to be inserted into only the type of
receptacle for which they specifically designed. Do not cut off the
round grounding pin in order to be able to fit into a two prong recep¬
tacle as this could cause injury and will void the warranty.

11. Power Sources: This product should be operated only from the
type of power source indicated on the marking label. If you are not
sure of the type of power supplied to your home, consult your appli¬
ance dealer or local power company.
12. Power-cord Protection: Power-supply cords should be routed
so they are not likely to be walked on or pinched by items placed upon
or against them. Pay particular attention to cords and plugs, conven¬
ience receptacles, and the point where they exit from the appliance.
13. Lightning: For added protection for this product during a lightning
storm, or when it is left unattended or unused for long periods of time,
the unit should be disconnected from power source.
14. Power Lines: An outside antenna system should not be located
in the vicinity of overhead power lines, other electric light or power cir¬
cuits, where it can fall into such power lines or circuits. When installing
an outside antenna system, extreme care should be taken to keep
from touching such power lines or circuits as contact with them may
be fatal.
15. Overloading: Do not overload wall outlets and extension cords as
this can result in risk of fire or electric shock.

EXAMPLE OF ANTENNA GROUNDING ACCORDING TO
NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED
IN ARTICLE 810-"RADIO AND TELEVISION
EQUIPMENT"
provide some protection against voltage surges and built-up static
charges.
a. Use No. 10 AWG (5.3mm) copper, No.8 AWG (8.4mm) alu¬
minum, No.7 AWG (10mm) copper-clad steel or bronze wire or
larger, as ground wire.
b. Secure antenna lead-in and ground wires to house with stand¬
off insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.
c. Mount antenna discharge unit as close as possible to where
lead-in enters house.

to qualified purchasers within the warranty period. The program provides a free equipment loan of like qualified equipment enabling seamless operation for the time
required to repair and return the unit.
The process is simple. Call our Customer Service desk requesting a return-merchandise-authorization (RMA) number for the failed equipment and ask for a loaner
unit. We will issue an invoice for the List Price of the loaner unit plus shipping costs. When you receive the loaner unit, pack the failed unit in the loaner unit’s box
