directly from the collector to the base of Q2 to a negative square wave at the collector of Q2, with to trigger the bistable circuit. R1, C1 circuit frequency

response is limited to about 3kHz to high sensitivity range. The power is turned on, the state of the bistable circuit Q4 off, Q3 saturated, D3 does

not shine. When MK1 received control signal, and a negative square wave output after two enlarged, negative spikes through D1 add to the base of Q3,

the circuit rapidly flip, D3 is lit after differential processing. When MK1 again connected to the control signal, the circuit and flipped, D3 is off. Circuit
