Charging the Internal Backup Battery

After installing the VC70, leave it powered on for 6 hours to fully charge
the internal backup battery. Note that the VC70 can charge the backup
battery while in Suspend mode, but not if power is turned Off with the
power switch.

reduced functionality (no heaters, USB, Serial, Ethernet, external
speaker interfaces and dimmed display backlight, and lower internal
speaker volume) to enable forklift battery replacement when drained.

fully charged. The data in the Flash memory or Flash file system is not
affected by the state of charge.
