Abstract
An electronic apparatus includes a sound collecting device, a storage device, a display device, and a control device. The storage device contains a normal spectrogram representing the operation sound of each of functional units, acquired when low-speed operation is normally performed, and a timing chart indicating a timing that each functional unit operates when the electronic apparatus performs the low-speed operation. The control device analyzes frequency of the sound data collected by the sound collecting device when the electronic apparatus performs the low-speed operation, and outputs the spectrogram, decides whether abnormal noise has occurred, by comparison between the outputted spectrogram and the normal spectrogram, identifies, upon deciding that abnormal noise has occurred, the functional unit that is a source of the abnormal noise, by comparison between the timing chart and the outputted spectrogram, and causes the display device to display a first screen indicating the identified functional unit.
