: B– Line.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
• Voltages and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
no mark : DVD STOP

: Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M
Ω
).
• Circled numbers refer to waveforms.
• Signal path.
