THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this 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
4
specified.
• % : indicates tolerance.
• ¢ : internal component.
• 2 : nonflammable resistor.
• 1 : fusible resistor.
• C : panel designation.
The components identified by mark ! or dotted
line with mark ! are critical for safety.
Replace only with part number specified.
• 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 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.
• Circled numbers refer to waveforms.
• Signal path.
F
: FM
g : VIDEO/MD
E
: PB (DECK A)
d
: PB (DECK B)
G
: REC (DECK B)
J
: CD
c : CD DIGITAL
• Abbreviation
CND : Canadian
For printed wiring boards.
Note:
• X : parts extracted from the component side.
• : internal component.
