Caution:
Pattern face side: Parts on the pattern face side seen from
(SIDE B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(SIDE A) the parts face are indicated.
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
1
/
4
W or less unless otherwise
specified.
• % : indicates tolerance.
• 2 : nonflammable resistor.
• 1 : fusible resistor.
• 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 : 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
c : DIGITAL
I : PHONO
• Abbreviation
CND :Canadian model
AUS :Australian model
MY :Malaysia model
SP :Singapore model
CH :Chinese model

Note:
• X : parts extracted from the component side.
• a : Through hole.
• b : Pattern from the side which enables seeing.
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 cri-
tiques pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro spécifié.
