7-5. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• p : parts mounted on the conductor side.
•
¢
: internal component.
• b : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Indication of transisitor.
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.
Note on Schematic Diagram:
• 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
/
4
W or less unless otherwise
specified.
•
¢
: internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• 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 : TUNER (FM/AM)
E : PLAYBACK (DECK A)
d : PLAYBACK (DECK B)
G : RECORD
J : CD PLAY (ANALOG OUT)
c : CD PLAY (DIGITAL OUT)
N : MIC INPUT
• Abbreviation
AR : Argentine model
AUS : Australian model

Note:
The components identi-
fied by mark ! or dotted
line with mark ! are criti-
cal for safety.
Replace only with part
number specified.
Note:
