W or less unless otherwise
specified.
• % : indicates tolerance.
•
f
: internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• 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 : FM
J : CD (ANALOG)
c : DVD (DIGITAL)

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.
Caution:
Pattern face side: Parts on the pattern face side seen from
