PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety characteristics.
These safety characteristics often pass unnoticed and the protection afforded by them cannot
necessarily be obtained by using replacement components rated for higher voltage, wattage, etc.
Replacement parts that have these special safety characteristics are identified in this manual
and its supplements; electrical components having such features are identified by in the
schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully.
The use of substitute replacement parts that do not have the same safety characteristics as
specified in the parts list may create shock, fire or other hazards.
