supplied to your home consult your television dealer or local power company. For television receivers designed to
operate from battery power, refer to the operating instructions.
9. This television receiver is equipped with a polarized alternating-current line plug (a plug having one blade widerthan 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.

14. 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 and in Canada Part 1 of the Canadian Electrical Code provides information with respect 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.
15. For added protection for this television 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. This will prevent damage to the receiver due to
lightning and power-line surges.
16. 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.
17. Unplug this television receiver 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 television receiver.
c. If the television receiver has been exposed to rain or water.
d. If the television receiver does not operate normally by 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 television receiver to normal operation.
e. If the television receiver has been dropped or the cabinet has been damaged.
f. When the television receiver exhibits a distinct change in performance - this indicates a need for service.
18. Do not attempt to service this television receiver yourself as opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service personnel.
19. When replacement parts are required, be sure the service technician has used 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.
20. Upon completion of any service or repairs to this television receiver, ask the service technician to perform routine safety
checks to determine that the television is in safe operating condition.
21. WARNING: To prevent fire or shock hazard, do not expose this appliance to rain or moisture.
