User’s Guide 3–8
3. Remove the battery from the battery cover by pulling up on
the back of the battery at the finger holes in the battery cover
4, then pulling the battery out of the battery cover 5.
Ä CAUTION: Because most of the applications and data you install on
your Pocket PC are held in memory (RAM), you will need to reinstall
them if the battery completely discharges or if the battery is removed
from the unit for more than a few minutes. Otherwise, when fully
charged, the internal backup battery saves the user-installed data for up
to 15 minutes when the standard battery is removed. Before removing
the battery, check to see that the internal backup battery is fully charged
by tapping Start > Settings > System tab > Power Icon.
You do not need to reinstall applications and data installed in the iPAQ
File Store folder because they are saved in nonvolatile memory.
Charging with the AC Adapter
The AC Adapter works in a standard electrical outlet. You can
also charge your Pocket PC in your automobile with an
Automobile Adapter that works in your vehicle’s electrical
cigarette lighter or a 12-volt power outlet.
