For schematic D iagram

- R esistors are in ohms, 1/8W unless otherwise noted.

- C ircled numbers refer to waveforms.

Note

Special note :

M ost semiconductor devices are electrostatically sensitive and therefore require the special handling techniques

described under the electrostatically sensitive (ES ) devices section of this service manual.

Note :

D o not use the part number shown on this drawing for ordering. T he correct part number is shown in the parts

list (m ay be slightly different or am ended since this drawing was prepared).

Important safety notices :

Components identi fied wi th the mark ! have the special characteristics for safety. When replacing any of thesecomponents. U se only the same type.
