When the P1 port of the processor 30 outputs the ultrasonic frequency signal, the signal is simultaneously limited by the fifth resistor R5 to make the second light emitting diode LED2 emit light to function as an indication for the operation of the ultrasonic drive circuit 10.
Further, a third indicating circuit 11 is also included, and the third indicating circuit 11 is connected in parallel to two ends of the first capacitor EC 1.

When an ultrasonic frequency signal output by a P1 port of the processor 30 is driven and output to the ultrasonic transducer BUZ1 through the first PNP transistor Q1, the ultrasonic frequency signal is also output to charge the first capacitor EC1, because the first light emitting diode LED1 is connected in parallel to two ends of the first capacitor EC1, when the voltage on the first capacitor EC1 reaches a voltage value for lighting the first light emitting diode LED1, the first light emitting diode LED1 discharges the electric quantity on the first capacitor EC1 through light emission, and when the voltage is reduced, the first light emitting diode LED1 is extinguished; the first capacitor EC1 is then charged again, so that the first light emitting diode LED1 lights up again, and the light emitting diode blinks to start the function of indicating the operation of the ultrasonic transducer BUZ 1.

When the P2 port of the processor 30 outputs a low frequency signal, the low frequency signal thereof simultaneously causes the third LED3 to emit light by the current limiting of the thirteenth resistor R13, and since the frequency of the low frequency signal is very low, the third LED3 is caused to emit light in a slow flashing light emitting state, so as to indicate that the low frequency electromagnetic wave driving circuit 20 is in an operating state.
