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. 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.
•%: indicates tolerance.
•
f
: internal component.
• C : panel designation.
• A : B+ Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
•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
f : AM/MW/LW
J : CD
c : CD-R/RW (MP3)
for printed wiring boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• x : parts mounted on the conductor side.
•
a
: Through hole.
• : Pattern from the side which enables seeing.
(The other layer’s patterns are not indicated.)
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.

Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.
Note:
