Common note on Printed Wiring Boards:
• Y : parts extracted from the conductor side.
•
f
: internal component.
• : Pattern from the side which enables seeing.
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.
*
IC502, IC801 is not replaceable
• Lead Layouts
surface
Lead layout of conventional IC CSP (chip size package)
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 Ω and
1
/4
W or less unless otherwise
specified.
• % : indicates tolerance.
•
f
: internal component.
• C : panel designation.
• A : B+ Line.
• Power voltage is dc 3V and fed with regulated dc power
supply from external power voltage jack.
• Voltages and waveforms are dc with respect to ground in
playback mode.
no mark : REC
( ) : PB
∗
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
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.

Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
piéce portant le numéro
spécifié.
