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 replace-
ment 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 fea-
tures 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 speci-
fied in the parts list may create shock, fire, or other
hazards.

Notes:
1. Do not use the part number shown on these draw-
ings for ordering. The correct part number is
shown in the parts list, and may be slightly different
or amended since these drawings were prepared.
2. To maintain original function and reliability of
repaired units, use only original replacement parts
which are listed with their part numbers in the parts
list section of the service manual.
3. Prefix symbol "CN" means "connector" (can dis-
connect and reconnect).
Prefix symbol "CL" means "wire-solder holes of the
PCB" (wire is soldered directly).
4. How to read converged lines.
