6-5. SCHEMATIC DIAGRAM – MAIN Board (1/4) – • See page 37 for Waveforms. See page 38 for IC Block Diagram.

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 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.

• Waveforms are taken with a oscilloscope.

• Power voltage is dc 1.5V and fed with regulated dc power

 

Voltage variations may be noted due to normal produc-
