For schematic diagrams
• 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.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS
AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
•
U
: 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 M
Ω
).
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
J
: CD
For printed wiring boards
•
X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
a
: Through hole.
•
f
: internal component.
•
b
: 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.
The components identified by
mark
0
or dotted line with mark
0
are critical for safety.
Replace only with part number
specified.
Les composants identifiés par une
marque

sont critiques pour la
sécurité.
Ne les remplacer que par une piéce
portant le numéro spécifié.
