• A : B+ Line.
• B : B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
•
no mark
: FM
( ) : AM/MW/SW
< > : CD PLAY
• Voltages are taken with 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 PLAY
F : FM
f : AM/MW/SW
L : AUX

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
Note:
The components identi-
fi ed by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specifi ed.
Note:
Les composants identifi és
par une marque 0 sont
critiques pour la sécurité.
Ne les remplacer que par
une piéce portant le nu-
méro spécifi é.
