Note:
Power voltage ls dc 3V and fed with regulated
dc power supply from battery terminal.
DC voltage are taken with digital multimeter
(input impedance 1MΩ or more)under no-signal
conditions.
Voltage values on signal input conditions are
taken when the signal is -60dB(OdB=1Vrms)and
fed with AF oscillator from MIC input terminal.
Voltage variations may be noted due to normal
production tolerances.
