Note:
The components identified by mark

• Power voltage is dc 6.0V and fed with regulated dc power
supply from cradle.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
