The UM3562 integrated circuit is a dedicated circuit found in many toys because it generates three types of weapon sounds, depending on the position of the programming key. Power is supplied from two common batteries and the transducer used must have an impedance of 64 ohms. At the same time the sound is emitted when the trigger is pressed, the LED lights up. The rate of repetition of shots in the case of the machine gun is adjusted in the trimpot. For increased power, the signal from pin 5 can be applied to an amplifier.
