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. 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 

drawings 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 

otherwise specified.

4. All capacitance values are indicated in 

µ

(P=10

-6

 

µ

F).

5. All voltages are DC voltages unless otherwise 

specified.

6. Electrical parts such as capacitors, connectors, 

diodes, 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.
