*:
Note:
Power voltage is 3.0 Vdc and fed with regulated dc power
supply from battery terminal.
DC valtage are taken with digital multimeter (input impedance
1 M
Z
or more) under no-signal conditions.
Voltage values on signal input conditions are taken when the
signal is
_
55 dB (0 dB = 1 Vrms) and fed with AF oscillator from
MIC input terminal.
