PURPOSE:To display the condition of diagnosis with high reliability by distinguishing the diagnosis results of devices from the generation of an intermittent sound and the level of the sound. CONSTITUTION:The start or end of each diagnosis phase is desplayed by the sound decided every diagnosis phase. The sounds of the diagnosis phase are distinguished from the generating frequency of intermittent sounds and the levels of these sounds. A display is given to a display part when an electronic device has no fault and a test is through with the final phase. If some fault is detected, the progress of the diagnosis phase is discontinued. Thus a user counts the generating frequency of the intermittent sound delivered from a speaker 28 at the final stage and informs the count result to a maintenance operator. |
