W or less unless otherwise
specified.
• % : indicates tolerance.
•
¢
: internal component.
• C : panel designation.
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• p : parts mounted on the conductor side.
• b : Pattern from the side which enables seeing.
• U : B+ Line.
• V : B– Line.
• 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.
