Advanced Power Management
The 2325 uses advanced power management (APM) to provide the
longest battery life. Control of the APM features is provided in the

utility on drive B of each 2325.
This section provides additional information for getting the most power
life out of a 2325 RF unit using the RangeLAN2 wireless LAN PC card.
Batteries
For RF units, LXE recommends the use of nickel metal-hydride (NiMH)
batteries. In general, a 2325 with an RF card should be able to get
through a normal 8-hour shift before the batteries need to be replaced or
recharged.
Doze Mode
After 8 seconds without a keypress, scanner input, or other system
activity, the 2325 goes into a power-saving state known as doze mode.
To maximize battery life, especially in an RF environment, try to avoid
accidental or unnecessary pressing of the keypad keys or triggers.
Auto-Off Timer
After a predetermined time without any system activity, the unit
automatically shuts off. The default auto-off timeout is 5 minutes. To
maximize battery life, you can set the timeout to a much shorter period.
Appendix C includes bar codes that provide auto-off settings as low as
20 seconds. You can also use the PM.COM utility to set the auto-off
timer.
Backlight
Use of the display backlight severely affects battery life in the 2325. For
RF applications, do not use the backlight unless it is absolutely
necessary. If you do need to use it, you can change the display’s auto-off
timer to a setting lower than the default (15 seconds).
