sure of the type of power supplied, contact your television dealer or local power company.
14. This display is 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 still doesn’t fit, contact your electrician to replace your obsolete outlet.
Do not bypass this safety feature of the polarized plug.
15. Do not allow anything to rest on or pinch the power cord. Do not locate this display
where the cord could be stepped on.
16. Do not overload wall outlets and extension cords as this can result in fire or electric shock.
17. Never push objects of any kind into this display through cabinet openings. This could
result in a fire or electric shock. Never spill liquid of any kind on the display.
18. If an outside antenna is connected to the television equipment, be sure the antenna
system is grounded so as to provide some protection against voltage surges and built-up
static charges. In the U.S. Section 810 of the National Electrical Code information is
provided regarding the 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 electrodes.
19. For additional safety 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. This
will prevent damage to the receiver due to lightning and power-line surges.
20. 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
avoid touching any power lines or circuits as contact with them could cause fatal injuries.
21. Unplug this display from the wall outlet and refer servicing to qualified service personnel
under the following conditions:
a. When the power cord or plug is damaged or frayed.
b. If liquid has been spilled into the display.
c. If the display has been exposed to rain or water.
d. If the display does not operate normally even after following the operating
instructions. Adjust only those controls that are covered by the operating
instructions as improper adjustment of other controls may result in damage and
will often require extensive work by a qualified technician to restore the display
to normal operation.
e. When the display exhibits a distinct change in performance, have it serviced by
an authorized service provider.
22. Do not attempt to service this display yourself as opening or removing covers may expose
you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
23. When replacement parts are required, be sure the service technician uses replacement
parts specified by the manufacturer that have the same characteristics as the original
part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
24. Upon completion of any service or repairs to this display, ask the service technician to
perform routine safety checks to determine that the display is in safe operating condition.
