လျှပ်စစ်ပစ်ခတ်မှုစမ်းသပ်မှု consists of a photoelectric control circuit composed of a photoelectric receiving tube and a laser light-emitting tube. When the photoelectric receiving tube receives a strong infrared laser, it is sent to the main control circuit U1 for processing, and then output to the horn to read out the voice of the laser gun hitting the receiving tube.
