PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in television receivers have special safety related characteristics. These
characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be
obtained by using replacement components rated for higher voltage, wattage, etc.
Replacement parts which have special safety characteristics are identified in this service manual.
Electrical components having such features are identified
in the parts data base and by bold
type in the parts list of this service manual. The replacement for any safety part should be identical in value
and characteristics.
