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 CPU264A board. To charge the large storage capacitor sufficiently, turn on the power of DVS-7000A 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.
