NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Board:
•
Y
: parts extracted from the conductor side.
•
b
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. U: µF,
pF: µµF 50 WV or less are not indicated except for
electrolytics and tantalums.
• If a numeric value of capacitor is a decimal function, the
preceding zero may be omitted.
(For example, .1 expresses 0.1)
• All resistors are in
Ω
and
1
/
4
W or less unless otherwise
specified.
•
f
: internal component.
•
2
: nonflammable resistor.
•
C
: panel designation.
•
U
: B+ Line.
•
V
: B– Line.
•
H
: adjustment for repair.
• 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.
F
: FM
f
: AM
E
: TAPE PLAY (DECK A)
d
: TAPE PLAY (DECK B)
G
: TAPE REC
J
: CD PLAY (ANALOG OUT)
c
: CD PLAY (DIGITAL OUT)
• Abbreviation
CND : Canadian model
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.
