Note
For schematic Diagram
- Resistors are in ohms, 1/8W unless otherwise noted.
Special note :
Most semiconductor devices are electrostatically sensitive and therefore require the special handling techniques described under the
“electrostatically sensitive (ES) devices” section of this service manual.
Important safety notices :
Components identified with the mark
0
have the special characteristics for safety. When replacing any of these components.
Use only the same type.
