Next, the operation of the CPU 11A in the abnormality notification circuit 10A after the battery power supply is down will be described with reference to the flowchart of FIG. Power supply compensation capacitor 1
8 is normally charged by the output of the DC power supply circuit 3 or the battery 5. If the voltage of the battery 5 drops and the power supply to the malfunction reporting circuit 10A is stopped while the CPU 11A is performing the malfunction monitoring / reporting operation of the equipment (step S-1), the power compensating capacitor 18 is used as the power supply. The CPU 11A of the abnormality reporting circuit 10A which is operating detects the battery voltage drop by the output of the battery voltage detection circuit 6 (step S-2), and moves the notification history data stored in the RAM 12 to the EEPROM 13 (step S-). 3). When the movement of the report history data is completed, the CPU
11A completes the operation and completely discharges the power supply compensation capacitor 18.

Further, in this embodiment, since the power source compensating capacitor 18 is always charged by the battery 5 or the DC power source circuit 3 when the apparatus is in operation, the power source compensating capacitor 18 is charged when the battery power is cut off.
