Note on Printed Wiring Boards:

•X: parts extracted from the component side.

•Y: parts extracted from the conductor side.

•b: Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

Caution:
Pattern face side: Parts on the pattern face side seen from
(Side A)					the pattern face are indicated.
Parts face side:					Parts on the parts face side seen from
(Side B)					the parts face are indicated.
• Indication of transistor.

Note on Schematic Diagram:

•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 Ω and 1/4 W or less unless otherwise specified.

•% : indicates tolerance.

•f : internal component.

•5: fusible resistor.

•C : panel designation.

The components identified by mark 0or dotted line with mark 0are critical for safety. Replace only with part number specified.

•A : B+ Line.

•B : B– Line.

•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal produc- tion tolerances.

•Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc- tion tolerances.

•Circled numbers refer to waveforms.

•Signal path. F : FM

J : CD PLAY

E : MD PLAY

j : MD REC

q : DIGITAL OPTICAL IN

d : TAPE IN (PLAY)

G : TAPE OUT (REC)
