1-1-4. Capacitor for Data Backup

To store a setup data and a real-time clock, the large storage capacitor (3 Farad) is mounted on the CPU-
264B board.
To charge the large storage capacitor sufficiently, turn on the power of DVS-7200A for more than about
thirty minutes. The sufficiently charged large storage capacitor enables data to be stored for about one
week in the normal temperature.
