Managing Battery Power
Data and files saved on Dolphin 9500 Series terminals may be stored in RAM; therefore, to help prevent data loss, maintain a
continuous power 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
Status Icons on page 4-25.
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.
The battery status indicator displays in the notification tray when the battery is low or critically low. If there is no indicator, the
battery is adequately charged. If the main battery is low and the terminal is in suspend mode, pressing the SCAN or Power button
does not wake the Dolphin terminal; you must replace the discharged battery with a fully charged battery.
Default Critical and Low Battery Points
Dolphin 9500 Series terminals are programmed to display warnings when the battery reaches critical and low battery points.
There are two DWORD value registry entries [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power] that
allow these warning points to be customized:
“CriticalBatt”=a
(10%)
This sets the Critical Battery point to 10 percent (a hex = 10 decimal). The critical battery setting is the point at which the customer
is warned that the battery charge is very low. This warning is posted every 3 minutes until the situation is corrected.
“LowBatt”=19
(25%)
This sets the Low battery point to 25 percent (19 hex = 25 decimal). The low battery setting is the point at which the user is notified
that the battery is low. The user is notified only once for a low battery.
Setting Critical and Low Battery Points
Developers can reset these parameters in the registry from 0 (no warning) to 99 (would nearly always warn). Warnings do not
appear when the terminal is on external power.
Note: You can also review and set these battery points in the RegEdit utility. Tap Start > Utils > RegEdit. Drill-down to
HKEY_LOCAL_MACHINE > System > CurrentControlSet > Control > Power. The Battery Points appear in a list in the
lower half of the window; tap on the Value Name to change the Value Data.
