Power voltage is dc 4.5 V and fed with regulated dc power
supply from battery terminal.
Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

 See page 11 for Waveforms and IC Block Diagrams.
Voltages are taken with a VOM (Input impedance 10 M
).
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.
