THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed
in each block.)
For schematic diagrams.
Note:
• 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

W or less unless otherwise
specified.
•
¢
: internal component.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : STOP
• 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.
J : CD
c : digital out
• Abbreviation
CND: Canadian model
AUS : Australian model
SP : Singapore model.
MY : Malaysia model.
For printed wiring boards.
Note:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
®
: Through hole.
• b : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)

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