PURPOSE:To check whether or not individual backup data have truly proper values by checking the backup data by using data for comparison which are prepared corresponding to the individual backup data. CONSTITUTION:When a control ON state is entered, the backup data are loaded in an I/F buffer 3 from a CMOS 1. Then the individual backup data which are loaded in the I//F buffer 3 are checked by using the data 4 for comparison. If it is judged that backup data does not have a proper value, an error is displayed and the abnormal backup data part is indicated. Thus, the individual backup data are checked by the data 4 for comparison which are prepared corresponding to the backup data. Consequently, the true propriety of the individual backup data is known. |
