Common note on Printed Wiring Board:

Y : parts extracted from the conductor side.

: Pattern from the side which enables seeing. (The other layer’s patterns are not indicated.)

Caution:

Pattern face side: Parts on the pattern face side seen from the

(Side B) pattern face are indicated.

Parts face side: Parts on the parts face side seen from the

(Side A)

parts face are indicated.

Main board is four-layer printed board.

However, the patterns of layers 2 and 3 have not been in- cluded in this diagrams.

*Replacement of IC801 on main board requires a special tool.

Common 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.

Total current is measured with Minidisc installed.

Power voltage is dc 3V and fed with regulated dc power supply from external power voltage jack.

Voltage and waveforms are dc with respect to ground under no-signal conditions.

: Impossible to measure

Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal produc- tion tolerances.

Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc- tion tolerances.

Circled numbers refer to waveforms.
