Note: 1. R1 = 1.2 M

Ω, T(transistor) = ß > 130, R2 = 470 Ω , S(speaker) = 1/4 w, 8 Ω; all typical.

2. R2=470

Ω ( typical ) to bypass extra current into base to get rid of waveform saturation

on collector .

3. Piezo buzzer resonant frequency being around 1K Hz is recommended.

4. Input switch could be replaced by CDS.

5.COUT,VOUT1,VOUT2 are tristate during stand by state.
