Managing The Battery; Charging The Battery - HP iPAQ rz1700 series User Manual

Your device is shipped with a partially charged internal battery.
It is recommended that you fully charge the device before setting
up the unit.
Note:
Even when not in use, the device uses battery power to run the
clock and maintain files. When at your desk, keep the device
plugged into an electrical outlet with the AC Adapter. When you
travel, carry with you the AC Adapter and sync cable.
Ä
CAUTION: Keep the battery charged. The programs and files you
install or create are stored in volatile RAM memory. If the battery
completely discharges, all user-installed programs and user data files
created will be erased and you will have to reinstall them. To prevent
losing valuable programs and files, keep the battery always charged.
Optionally, you can store a limited number of programs and files in the
iPAQ File Store folder so that if the battery completely discharges, they
will not be lost.

Charging the Battery

The AC Adapter works with any household electrical outlet. You
can also purchase an adapter that works with your vehicle
cigarette lighter or 12 Volt power outlet.
Ä
CAUTION: Use only the AC Adapter that came with your device to
charge it.
