Then a sound source device 10 is operated to sound a voice signal of a prescribed frequency from a speaker 11. The speaker 11 approaches a transmitter of the portable terminal equipment 1 to input a voice signal of a prescribed frequency to the portable terminal equipment 1. Furthermore, the test personnel inputs a voice signal outputted from the voice terminal equipment 7 to a hit detection recorder 8 to discriminate a hit based on an alarm tone or an alarm lamp ancillary to the hit detection recorder 8 and records number of times of hits.
