SCHEMATIC DIAGRAMS / CBA'S AND TEST POINTS Standard Notes WARNING Many electrical and mechanical parts in this chassis have special characteristics. These 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 the mark " # " in the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully.

Standard Notes
WARNING
Many electrical and mechanical parts in this chassis
have special characteristics. These 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 the mark "
#
" 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.
