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 ∝F unless otherwise noted. pF: ∝∝F 50 WV or less are not indicated except for electrolytics and tantalums.
•All resistors are in Ω and 1/4 W or less unless otherwise specified.
•f : internal component.
•C: panel designation.

∗: Impossible to measure
•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.
