DIAGRAMS
• Waveforms
— MAIN Board —
for schematic diagram:
Note:
• 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
/
4
W or less unless otherwise
specified.
• f : internal component.
• C : panel designation.
for printed wiring boards:
Note:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
a
: Through hole.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
•Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : FM
( ): AM or MW
<>: CD
∗
: Impossible measurement point
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
J : CD
F : FM
f : AM or MW
g : AUDIO
L : AUX
c : iPod
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.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
