PURPOSE:To discriminate the kind of abnormality only by listening to a warning sound or warning melody and make a response fast by generating a different musical sound corresponding to the kind of the detected abnormality. CONSTITUTION:For example, a specific address of a memory is read out to check whether or not the kind of the abnormality is A and when so, a melody (a) is selected among various melody data stored in a ROM 11; and its data are read out and a sounding body 14 is controlled to sound the melody. When the kind of the abnormality is not A, it is checked whether or not the kind of the abnormality is B, and when so, a melody (b) is generated; when the kind of the abnormality is C, a melody (c) is generated similarly. When no corresponding kind is found, a melody (d) is generated. After the melody corresponding to the kind of the abnormality is thus generated, the same abnormality processing as usual is performed and processing for displaying the kind of the abnormality on the display unit of a panel 15 is included therein. |
