2-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
Note on Printed Wiring Boards: X : parts extracted from the component side. Y : parts extracted from the conductor side. f : internal component. 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. Note on Schematic Diagrams: 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 and 1/4 W or less unless otherwise specified. f : internal component. C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. U : B+ Line. H : adjustment for repair. Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords. Voltages are taken with a VOM (Input impedance 10 M). Voltage 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. F : FM f : MW/LW E : MD Model Identification The destination is expressed with the model according to the language of Program Rom mounted in the set. How to identify the model is described below. POWER BOARD (Component Side)
