• Power voltage is dc 3.6 V and fed with regulated dc power
supply from external power voltage jack (CN301).
• Voltages and waveforms are dc with respect to ground un-
der no-signal conditions.

• 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
