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.
