Power Low Indication

Main Battery

When the main battery becomes low, a warning message
will be shown on the screen.
When the low battery message appears, the main battery can
continue to supply power for about 30 more minutes. When the
HT630 reaches the system power cutoff point it will automatically
turn off. The HT630 will store the data contents in the RTC and RAM but cannot be
turned on again until the batteries have been recharged or replaced.

Lithium Backup Battery

When the Lithium backup battery doesn't have enough capacity
to back up the system, a message will appear on the screen.
In this situation, you should upload your data from the HT630
immediately and recharge or replace with a new Lithium battery.
