ABSTRACT:
A microcomputer gives instructions to a sound processor to set a value of a volume prescribing a sound volume outputted through a speaker to a predetermined value as a parameter. The sound processor stores the value of the parameter in a RAM and sets a sound volume corresponding to the value of stored parameter. The microcomputer reads the value of parameter which is set practically by a sound processor, and decides whether the value of the parameter is different from the value that the setting thereof has been instructed or not, and decides that abnormality has been generated in the sound processor when they are different from each other, thus making it possible to detect generation of abnormality in an apparatus that has no function of detecting generation of abnormality.
