Note on Schematic Diagram:
• 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  and
1
/4 W or less unless otherwise
specifi ed.
•
2
: nonfl ammable resistor.
• C : panel designation.
• Note for Printed Wiring Boards and Schematic Diagrams
• A : B+ Line.
• B : B– Line.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER
< > : CD PLAY
*
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F : AUDIO
E : USB

Note on Printed Wiring Board:
• X : parts extracted from the component side.
• : parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.
(The other layer’s patterns are not indicated.)
Caution:

(Component Side)
Parts on the pattern face side seen from
the pattern face are indicated.
Parts on the parts face side seen from
the parts face are indicated.
Note: The components identifi ed by mark 0 or
dotted line with mark 0 are critical for safety.
Replace only with part number specifi ed.
