Note on Schematic Diagram:
•
All capacitors are in
µ
F unless otherwise noted. (p: pF)
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.
•
f
: internal component.
•
2 : nonflammable resistor.
•
5 : fusible resistor.
•
C
: panel designation.
•
A : B+ Line.
•
B
: B– Line.
•
C
: adjustment for repair.
•
Voltages and waveforms are dc with respect to ground
under no-signal conditions.
– DMB10, MIB01 and IO Boards –

•
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.

Note on Printed Wiring Board:
•
X : parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
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.
•
DMB10 and MIB01 boards are multi-layer printed board.
However, the patterns of intermediate layers have not been
included in diagrams.
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

Ne les remplacer que par une
pièce por tant le numéro
spécifié.
