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. (p: pF)
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.
f
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
Note: The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specified.
• A : B+ Line.
• B : B– Line.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : FM
• 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.

: TUNER (FM/AM)
L : VIDEO (AUDIO)
I : VIDEO
J
: CD (ANALOG)
c : CD (DIGITAL)
• Abbreviation
AUS : Australian model.
