Note:
. Power voltage is 3.0 Vdc and fed with regulated dc power
supply from battery terminal.
. Reference input signal is _55 dB (0 dB = 1 Vrms) and fed with
AF oscillator from MIC connector.
. For measuring points (A to J), see schematic diagram.
. Level values are referential values measured with AF level
meter.

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 MZ 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.
