NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS

Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• : internal component.
f
• : Pattern from the side which enables seeing.
Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
• MB board is multi-layer board.
However, the patterns of intermediate-layer not been included
in diagram.
Note on Schematic Diagram:
• 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 / W or less unless otherwise

specified.
• : internal component.
f
• C : panel designation.
Note: The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specified.
• A : B+ Line.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : DVD PLAY
( ) : CD PLAY
• 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.
c : DVD PLAY
J
: CD PLAY
L : DVD/CD PLAY (VIDEO OUT)
F
: DVD/CD PLAY (AUDIO OUT)
I : DVD/CD PLAY (DIGITAL OUT)
• Abbreviation
