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 spe-
cial 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 µF
(P=10
-6
µF).
5. All voltages are DC voltages unless otherwise
specified.
