ventilation and to ensure reliable operation of the product and to
protect it from overheating, and these openings must not be
blocked or covered.  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

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
operating instructions.

12. Grounding or Polarization – This product may be equipped with

a polarized alternating-current line plug (a plug having one blade
wider than the other).  This plug will fit into the power outlet
only one way.  This is a safety feature.  If you are unable to
insert the plug fully into the outlet, try reversing the plug.  If the
plug should still fail to fit, contact your electrician to replace your
obsolete outlet.  Do not defeat the safety purpose of the
polarized 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.

15. 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, 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.  See Figure A.

16. Lightning – For added protection for this product 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 system.  This will prevent
damage to the product due to lightning and power-line surges.

17. 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 circuits as contact with them might be fatal.

18. Overloading – Do not overload wall outlets, extension cords, or

integral convenience receptacles as this can result in a risk of
fire or electric shock.

19. Object and Liquid Entry – Never push objects of any kind into

this product through openings as they may touch dangerous
voltage points or short-out parts that could result in a fire or
electric shock.  Never spill liquid of any kind on the product.

opening or removing covers may expose you to dangerous
voltage or other hazards.  Refer all servicing to qualified service
personnel.

product,

c) If the product has been exposed to rain or water,
d) If the product does not operate normally by following the

operating instructions.  Adjust only those controls that are
covered by the operating instructions as an improper
adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the product to its normal operation,

e) If the product has been dropped or damaged in any way, and
f) When the product exhibits a distinct change in performance

– this indicates a need for service.

22. Replacement Parts – When replacement parts are required, be

specified by the manufacturer or have the same characteristics
as the original part.  Unauthorized substitutions may result in
fire, electric shock, or other hazards.

The lightning flash with arrowhead
symbol, within an equilateral triangle, is
intended to alert the user to the presence
