Default Critical and Low Battery Points
Dolphin terminals are programmed to display warnings when the battery reaches critical and low battery
points. The following registry entry sets both warning points:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power]
There are two DWORD values in this registry entry: LowBatt and CriticalBatt. The default values for these
entries are as follows:
LowBatt=19 (25%)
This sets the Low Battery point to 25% (19 hex=25 decimal). When the battery hits the
percentage charge specified here, the user is notified by this icon in the Navigation bar
If the main battery is low and the terminal is in suspend mode, pressing the SCAN or Power
button won't wake the Dolphin terminal; you must replace the discharged battery with a battery
charged over 25% mark before you can resume terminal operation.
CriticalBatt=a (10%)
This sets the Critical Battery point to 10% (a hex= 0 decimal). When the battery hits the
percentage charge specified here, the user is notified by this icon in the Navigation bar
Note: Warnings do not appear when the terminal is on external power.
Setting Critical and Low Battery Points
Developers can re-reset the default battery points in the RegEdit Power Tool.
1. Tap Start > Power Tools > RegEdit.
2. Drill-down to HKEY_LOCAL_MACHINE > System > CurrentControlSet > Control > Power. The
CriticalBatt and LowBatt values appear in the list.
3. Tap the Value Name to change the Value Data. You can reset the Value Data from 0 (no warning)
to 99 (would warn whenever the charge drops below 99%).
4. Tap OK to save changes.
Note: For more information about the RegEdit Power Tool, refer to the Dolphin Power Tools User's Guide, which is
available for download at www.honeywell.com/aidc.
