• Power voltage is dc 3.3 V and fed with regulated dc power supply
from battery terminal.
• Voltages and waveforms are dc with respect to ground under no-
signal conditions.
no mark : CD PLAY
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production toler-
ances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler-
ances.
• Circled numbers refer to waveforms.
• Signal path.
