• NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed
in each block.)
For schematic diagrams.
Note:
• 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

W or less unless otherwise
specified.
f
: internal component.
C
: panel designation.
For printed wiring boards.
Note:
• X
: parts extracted from the component side.
• Y
: parts extracted from the conductor side.
a
: Through hole.
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)

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