� Note for Printed Wiring Boards and Schematic Diagrams
Note on Schematic Diagrams. � All capacitors are in µF unless otherwise noted. (p: pF) 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. � f : internal tolerance. � 2 : nonflammable resistor. � 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. Note: Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une piéce portant le numéro spécifié. Note on Printed Wiring Boards. � X : parts extracted from the component side � Y : parts extracted from the conductor side � a : Through hole � : Pattern from the side which enables seeing (The other layers' 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.

� A : B+ Line. � Voltages and waveforms are dc with respect to ground under nosignal conditions. no mark : DVD ( ) : FM � 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 : AUDIO d : TUNER f : DIGITAL IN E :Y r : COMPONENT VIDEO L : VIDEO
