SCHEMATIC DIAGRAMS / CBA'S AND TEST POINTS
Standard Notes
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. Resistor wattages are 1/4W or 1/6W unless otherwise specified.
4. All capacitance values are indicated in µF (P = 10
5. All voltages are DC voltages unless otherwise specified.
