THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) Common Note on Schematic Diagrams: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. All resistors are in � and 1/4 W or less unless otherwise specified. f : internal component. C : panel designation. A : B+ Line. Power voltage is dc 3V and fed with regulated dc power supply from battery terminal.
