Note on Schematic Diagram: MAIN SECTION

• All capacitors are in

F unless otherwise noted. pF:

µµ

50 WV or less are not indicated except for electrolytics
and tantalums.

• All resistors are in

Ω

and

W or less unless otherwise

specified.

•

: internal component.

Note:

The components identified by mark

or dotted

line with mark

are critical for safety.

Replace only with part number specified.

•

: B+ Line.

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

supply from battery terminal.

• Voltages and waveforms are dc with respect to ground

under no-signal conditions.
no mark : PLAY

• 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.
• Signal path.

: Analog

: Digital

•

Replacement of IC601 used in this set requires a special
tool.

•

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 Boards: MAIN SECTION

•

: parts extracted from the component side.

•

: Pattern from the side which enables seeing.

(The other layers' 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 boards is four-layer pritnted board.

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

MAIN BOARD SUB ASSY

• Audio board is supplied with main board sub ASSY.
• Audio board can't be moved away from main board.
