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

(The other layer's patterns are not indicated.)
• Schematic diagrams.
• All capacitors are in

and 1/4W or less unless otherwise speci-
fied.
•

• Voltage and waveforms are dc with respect to ground under no-
signal conditions.
no mark : STOP
• Voltages are taken with a VOM (Input impedance 10M
Ω
).
Voltage variations may be noted due to normal production tol-
erances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tol-
erances.
• Circled numbers refer to waveforms.
• Signal path.
