Note for Printed Wiring Boards and Schematic Diagrams
Note on Printed Wiring Boards:
•
X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
f
: internal component.
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
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.
•
DIAT AMP board is multi-layer printed board.
However, the patterns of intermediate layers have not been
included in diagrams.

Note on Schematic Diagram:
•
All capacitors are in

50 WV or less are not indicated except for electrolytics
and tantalums.
•
All resistors are in 
Ω
 and

specified.
•
f
: internal component.
•
2
: nonflammable resistor.
•
C
: panel designation.
•
A
: B+ Line.
•
Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
Note: When mesurering voltages and waveforms, con-
nect with HCD-SB500W (HCD-SB500W states:
DVD play).
no mark : DVD PLAY
∗
: Impossible to measure
•
Voltages are taken with a VOM (Input impedance 10 M
Ω
).
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.
