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. 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

(P=10

-6

 

µ

F).

5. All voltages are DC voltages unless otherwise

specified.
