supply to the terminal. When the main battery pack becomes low, the Low Battery Charge icon appears in the notification tray at
the top of the screen. The Critical icon appears when the battery is critically low. There is also a Low Battery icon that appears
when the backup battery is low. For details about these icons, see

Letting the backup battery become fully discharged causes the terminal to lose all data in RAM. Therefore, you should keep a
charged battery pack in the Dolphin at all times. The internal battery discharges prematurely if there is not at least a partially
charged battery in the terminal. When you remove a battery pack, insert another charged battery pack in the Dolphin.
