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 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
/

W or less unless otherwise
specified.
•
¢
: internal component.
•
2
: nonflammable resistor.
•
5
: fusible resistor.
•
C
: panel designation.
For printed wiring boards.
Note:
•
X
: parts extracted from the component side.
•
®
: Through hole.
•
b
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
•
U
: B+ Line.
•
V
: B– Line.
•
H
: adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
no mark : STOP
• Circled numbers refer to waveforms.
• Signal path.
J
: CD
c
: digital out
• Abbreviation
CND : Canadian model.
