Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 V or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1 / W or less unless otherwise
4
specified.
• 2 : nonflammable resistor.
• C : panel designation.
The components identified by mark 0
or dotted line with mark 0 are critical for
safety.
Replace only with part number specified.
Les composants identifiés par une marque
0 sont critiques pour la sécurité.
Ne les remplacer que par une piéce portant
le numéro spécifié.
• A : B+ Line.
• B : B– Line.
• H : Adjustment for repair.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER
• 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 : AUDIO (DIGITAL)
F : AUDIO (ANALOG)
f : TUNER (FM)
L : VIDEO
E : USB
J : CD/DVD PLAY
N : MIC
a : BLUETOOTH
