DIAGRAMS
For schematic diagrams.
Note:
• All capacitors are in µF 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.
• % : indicates tolerance.
•
f
: internal component.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
No mark : FM
• 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.
• Circled numbers refer to waveforms.
• Signal path.
F : ANALOG
J : DIGITAL
c : DVD

CND : Canadian model
MY : Malaysia model
SP : Singapore model
CH : Chinese model
MX : Mexican model
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this necessary note is printed in each block.)
Note:
The components identified by
mark 0 or dotted line with mark
0 are critical 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.

For printed wiring boards.
Note:
• X : parts extracted from the component side.
•
a
: Through hole.
•
f
: internal component.
• : Pattern from the side which enables seeing.
Caution:
Pattern face side: Parts on the pattern face side seen from
(Side A) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side B) the parts face are indicated.
