5-2. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Schematic Diagram: · 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. · U : B+ Line. · Power voltage is dc 5.8 V and fed with regulated dc power supply to 3 (EXT +B) pin of the jack connector (J1). · Voltages are dc with respect to ground in TEST mode. · Voltages are taken with a VOM (Input impedance 10 M). Voltages variations may be noted due to normal production tolerances. · Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. · Circled numbers refer to waveforms. · Signal path. N : RX O : TX Note on Printed Wiring Boards: · X : parts extracted from the component side. · b : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Conductor Side) Parts face side: (Component Side) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.
