SAFETY INSTRUCTIONS
The openings should never be blocked by
placing the product on a bed, sofa, rug, or
other similar surface. This product should
not be placed in a built-in installation such
as a bookcase or rack unless proper ventila-
tion is provided or the manufacturer’s
instructions have been adhered to.
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 supply to your home, consult your
product dealer or local power company. For
products intended to operate from battery
power, or other sources, refer to the operat-
ing instructions.
12. Power-Cord Polarization
This product is equipped with a three-wire
grounding type plug, a plug having a third
(grounding) pin. This plug will only fit into
the grounding-type power outlet. This is a
safety feature. If you are unable to insert the
plug into the outlet, contact your electrician
to replace your obsolete outlet. Do not
defeat the safety purpose of the grounding-
type plug.
13. Power-Cord Protection
Power-supply cords should be routed so
that they are not likely to be walked on or
pinched by items placed upon or against
them, paying particular attention to cords at
plugs, convenience receptacles, and the
point where they exit from the product.
14. Outdoor Antenna Grounding
If an outside antenna or cable system is
connected to the product, be sure the
antenna or cable system is grounded so as
to provide some protection against voltage
surges and built-up static charges. Article
810 of the National Electrical Code (U.S.A.),
ANSI/ NFPA 70 provides information with
regard to proper grounding of the mast and
supporting structure, grounding of the lead-
in wire to an antenna discharge unit, size of
grounding conductors, location of antenna-
discharge unit, connection to grounding
electrodes, and requirements for the
grounding electrode.
15. Lightning
For added protection for this product
(receiver) during a lightning storm, or when
it is left unattended and unused for long
periods of time, unplug it from the wall outlet
and disconnect the antenna or cable sys-
tem. This will prevent damage to the product
due to lightning and power-line surges.
16. Power Lines
An outside antenna system should not be
located in the vicinity of overhead power
lines or other electric light or power circuits,
or 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 cir-
cuits as contact with them might be fatal.
17. Overloading
Do not overload wall outlets and extension
cords as this can result in a risk of fire or
electric shock.
18. Object and Liquid Entry
Never push objects of any kind into this
