You can view the amount of battery power remaining for both the main battery and the backup battery. The main battery provides the HP iPAQ with power when it is not physically connected to the cradle or AC adapter. The internal backup battery provides the HP iPAQ with enough power to maintain data when you remove the battery for short periods of time. When the backup battery is fully charged, it maintains data for up to 15 minutes. However, you should always re-insert the main battery (extended or standard) back into the device immediately to minimize the drain on the backup battery. If the main or backup battery charge level is low, recharge the battery by connecting the HP iPAQ to AC power using the cradle or the AC adapter or insert a fully charged battery into the HP iPAQ. When the HP iPAQ turns off (due to low battery level) and does not turn on again, you have only up to 72 hours (if using default setting) to recharge the battery before you lose data. For information on purchasing an optional standard or extended life battery, visit the Cingular site at www.cingular.com/accessories or visit a Cingular retail outlet. CAUTION: Do not allow the main battery and back up battery installed in your HP iPAQ to completely deplete. Doing so will not harm your HP iPAQ or the batteries, but your device will lose all data not stored in File Store (ROM). Depleting the batteries completely is similar to performing a hard reset. 9
