• Total current is measured with MD installed.
• Power voltage is dc 3 V and fed with regulated dc power

supply from DC IN 3 V jack (J601).

• Voltages and waveforms are dc with respect to ground in

playback mode.

• Voltages are taken with a VOM (Input impedance 10 M

Ω

).

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.

• The voltage and waveform of CSP (chip size package)

cannot be measured, because its lead layout is different
form that of conventional IC.

Note on Printed Wiring Board:
•

X

: parts extracted from the component side.

•

Y

: parts extracted from the conductor side.

•

(The other layers' patterns are not indicated.)

Caution:
Pattern face side:

Parts on the pattern face side seen from

(Conductor Side)

the pattern face are indicated.

• MAIN board is four-layer printed board.

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