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.

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. All resistance values are indicated in ohms (K=10
3
,
M=10
6
).
3. Resistor wattages are 1/4W or 1/6W unless other-
wise specified.
4. All capacitance values are indicated in
µ
F
(P=10
-6
µ
F).
5. All voltages are DC voltages unless otherwise speci-
fied.
6. Electrical parts such as capacitors, connectors, di-
odes, IC's, transistors, resistors, switches, and fuses
are identified by four digits. The first two digits are
not shown for each component. In each block of the
diagram, there is a note such as shown below to
indicate these abbreviated two digits.
