Checking the Battery Status
If the battery level becomes low in the course of normal use, a status icon
appears on the device screen indicating low or very low battery status. In both
cases, perform an ActiveSync / Windows Mobile Cente operation to back up
your data, and then recharge your device as soon as possible.
CAUTION! Once the device is shut down, you should recharge the device
within 48 hours. Otherwise you will lose all data including files
stored in the RAM memory.
