Running your Handheld PC
Batteries and power
You can run your Handheld PC on battery power or with the AC adapter. In
addition, the Backup battery provides protection against loss of data. The main
battery requires rechargeable Li-ion battery pack. If you run your Handheld PC on
main battery while using a high power consumption device such as a PC Card,
your battery will drain before long. It is recommended that you use the AC
adapter when a PC Card is in use.
Backup battery is a rechargeable coin cell. It is charged from main
battery or AC adapter and needs not to change.
After you start using your Handheld PC, you must maintain a constant supply of
power or all data you have entered will be erased. If your Handheld PC does not
operate after you have not used it for a long time, the main battery may have run
down. If you believe this is the case, connect the AC adapter to charge
rechargeable Li-ion battery pack.
If you have not used your handheld PC for a long time or you use it in case the
first time rechargeable backup battery may have run down and "Backup Battery
Very Low " message will be displayed. In this case, please continue to connect
the AC adapter or main battery more than one hour minutes for charging
rechargeable backup battery.
