ng well with 5 of IC2 transform R5. By the frequency from IC1 pray contact compute up with the frequency by IC2 launch will valuable about 440 Hz - 550 Hz the frequency had with the intention of to sent arrive out pin 3 ways. Which remain take flatter up of IC2 the connection goes to grasp along well with B of Q1 in lieu of enlarge the trend comes to sing bail get to the sound of the circuit with the purpose of comes unacceptable resemble the sound of regulate distress signal.
