THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this necessary note is printed in each block.)

For schematic diagrams. Note:

• 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 Ω and 1/ specified.

• % : indicates tolerance.

• 2 : nonflammable resistor.

• 1 : 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.

• U : B+ Line.

• V : B– Line.

• H : adjustment for repair.

• Voltages and waveforms are dc with respect to ground

under no-signal (detuned) conditions. No mark : FM

• Voltages are taken with a V OM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

• Waveforms are taken with a oscilloscope.

• Circled numbers refer to waveforms .

• Signal path.

F : FM J : CD c : DIGITAL I : PHONO

W or less unless otherwise

4

For printed wiring boards. Note:

• X : parts extracted from the component side.

• a : Through hole.

• b : Pattern from the side which enables seeing.

Caution: Pattern face side: Parts on the pattern face side seen from (SIDE B) the pattern face are indicated. Parts face side: Parts on the parts face side seen from (SIDE A) the parts face are indicated.
