3 - 9
If the main battery is low and the terminal is in sleep mode, pressing the ON/SCAN button or the scan trigger will not wake up
the Dolphin 7400/7450 terminal; you must replace the discharged battery with a fully charged battery.
Setting Critical and Low Battery Points
The Dolphin 7400/7450 may be programmed to display warnings when the battery reaches critical and low battery points. There
are two entries defined in the registry. The specific settings are:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power]
"CriticalBatt"=dword:a
"LowBatt"=dword:19
"CriticalBatt"=dword:a
This sets the Critical Battery point to 10 percent (a hex = 10 decimal). The critical battery is the point at which the customer is
warned that the battery charge is very low. This warning will be posted every 3 minutes until the situation is corrected.
"LowBatt"=dword:19
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 alerted
that the battery is low. The user is notified only once for a low battery.
These are the default values. Developers can set these parameters from 0 (no warning at all) to 99 (would nearly always warn).
The warnings do not appear when the terminal is on external power.
Using the Power Control Panel
The Power control panel displays information about current battery status and allows you to set options that can conserve battery
power.
There is also a battery usage indicator displayed. This indicator represents the total cumulative time that the current main battery
pack has been in use. If the main battery is replaced with a new battery pack, the indicator will reset to 0:00. Each battery is
uniquely identified with a serial number that the Dolphin terminal uses to track cumulative time. Also, if the terminal is placed in
a HomeBase and is running on external power, the indicator will cease counting. When the terminal is removed from the
HomeBase, the timer will resume.
