the collector directly fed to Q2 amplification, a negative square wave at the collector of Q2, used to trigger bistable


circuit. R1 C1, the circuit frequency response for high sensitivity limit in the range of about 3kHz. When the power is


switched on, the state of the bistable circuit is Q4, Q3 saturation, D3 is not bright. When the MK1 receives the control


signal, after two stages of amplification, the output of a negative square wave, after the differential treatment of the


negative pulse through the D1 to the base of the Q3, so that the circuit quickly turned, D3 is lit. When the MK1 is


connected to the control signal, the circuit turns again and the D3 goes out.
