f
: internal component.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
•Power voltage is dc 4.5V and fed with regulated dc power
supply from pin 1 and 3 of CN901 on the BATTERY
board, and from pin 2 and 3 as well.

•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
pièce portant le numéro
spécifié.
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• W : indicates side identified with part number.
•
f
: internal component.
• : 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
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
