• Note for Printed Wiring Boards and Schematic Diagrams
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:
Pattern face side:
Parts on the pattern face side seen
(Conductor Side)
from the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(Component Side)
the parts face are indicated.
• MOTHERBOARD board is multi-layer printed board. However,
the patterns of intermediate layers have not been included in
diagrams.

• Voltages are taken with VOM (Input impedance 10 M).
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.
