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 diagram: • 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 Ω and 1/4 W or less unless otherwise specified. • f : internal component. • 2 : nonflammable resistor. • 5 : fusible 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. • A : B+ Line. • B : B- Line. • Voltage and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM • Voltages are taken with a VOM (Input impedance 10 MΩ). 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 : TUNER (FM/AM) L : VIDEO (AUDIO) I : VIDEO J : DVD (DIGITAL) c : CD (ANALOG) • Abbreviation AUS : Australian model MY : Malaysia model SP : Singapore model TH : Thai model AR : Argentina model E51 : Chilean and Peruvian models MX : Mexican model for printed wiring boards: • X : parts extracted from the component side. • f : internal component. • : Pattern from the side which enables seeing. Caution: Pattern face side: Parts on the pattern face side seen from the (Side B) pattern face are indicated. Parts face side: Parts on the parts face side seen from the (Side A) parts face are indicated. • Abbreviation AUS : Australian model MY : Malaysia model SP : Singapore model TH : Thai model E51 : Chilean and Peruvian models MX : Mexican model C Q These are omitted.
