OPERATION OF YOUR SET

18.

This television set 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 at your home, consult your television dealer or local power company.  For television
sets designed to operate from battery power, refer to the operating instructions.

19.

If the television set does not operate normally by following the operating instructions, unplug this television set from the
wall outlet and refer servicing to qualified service personnel.  Adjust only those controls that are covered in 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 set to normal operation.

20.

When going on a holiday :  If your television set is to remain unused for a period of time, for instance, when you go on
a holiday, turn the television set 

and unplug the television set from the wall outlet.

IF THE SET DOES NOT OPERATE PROPERLY

21. If you are unable to restore normal operation by following the detailed procedure in your operating instructions,

do not attempt any further adjustment.  Unplug the set and call your dealer or service technician.

22. Whenever the television set is damaged or fails, or a distinct change in performance indicates a need for

service, unplug the set and have it checked by a professional service technician.

23. It is normal for some TV sets to make occasional snapping or popping sounds, particularly when being

turned on or off.  If the snapping or popping is continuous or frequent, unplug the set and consult your
dealer or service technician.

FOR SERVICE AND MODIFICATION

24. Do not use attachments not recommended by the television set manufacturer as they may cause hazards.

25. 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.

26. Upon completion of any service or repairs to the television  set, ask the service  technician  to  perform

routine safety checks to determine that the television is in safe operating condition.
