CDX-3700 E Model 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 · 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. · % : indicates tolerance. ў · : internal component. · C : panel designation. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. · U : B+ Line. · 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 : AM J : CD · (( )) : Page of supplement-1. For printed wiring boards · Y : parts extracted from the conductor side. ® · : Through hole. ў · : internal component. · b : Pattern from the side which enables seeing. (The other layer's patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A) · (( 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. SERVICE MANUAL SUPPLEMENT-1 File this supplement with the service manual. Subject : Change of Main and Key Boards (ECN-CSB00629) When performing service and inspection, check the suffix of the part number of the main and key boards. 1.
