LOW BATTERY ALERT
When backup battery level drops to “Very Low”, the mobile computer prompts a “Backup
Battery Very Low” warning to alert users that backup battery level is almost drained out.
Backup battery is rechargeable by the main battery pack or the power adapter. Low backup
battery puts DRAM data in great danger. Remember to save data from time to time or keep
a fully charged battery at hand for replacement.
Once backup battery drains out completely, the data in DRAM is gone. Any data that has not
been saved will be lost!
