DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)
Note on Schematic Diagram:
•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.
•¢ : internal component.
•C: panel designation.
