THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
Common Note on Schematic Diagrams:
• 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.
•
f
: internal component.
• C : panel designation.
• A : B+ Line.
• H : adjustment for repair.
•Total current is measured with no cassette installed.
•Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
•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.
F : FM
f : MW
E : PB
a : REC
J : CD
c : CD (DIGITAL)
•Abbreviation
CND : Canadian model
IT : Italian model
EE : East European model
SP : Singapore model
AUS: Australian model
Common Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
f
: internal component.
• : Pattern from the side which enables seeing.

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.
