Note on Schematic Diagram:
•All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums.
•All resistors are in Ω and 1/4 W or less unless otherwise specified.
•% : indicates tolerance.
Note: The components identified by mark 0or dotted line with mark 0are critical for safety.
Replace only with part number specified.
