Charging the Battery
Before using the terminal for the first time, you need to charge it for about 16
hours. After that, you can charge the terminal for 4 hours to recharge the
battery to full capacity. Charge the terminal using the USB charging cable or
the docking station.
CAUTION! Operating the terminal for the first time without the AC adapter, and
without fully charging the backup battery may result in loss of data
stored in RAM memory. When the main battery is removed, the
backup battery retains RAM data in memory for 8 hours. Please
charge the battery for the period to avoid data loss in RAM
memory.
NOTE: Turn the backup battery switch on before charging the battery. Data
you entered may not be properly stored until the built-in backup battery
has been fully charged.
Charging the battery with USB charging cable
1. Connect the USB charging cable to PA550 (1).
2. Plug the AC adapter cable into the power jack of the USB charging cable
(2).
3. Plug the AC adapter cord into an electrical outlet (3).
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 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
