Charging the Battery
You must charge your Treo 650 fully before using it. It may not turn on at all when
you first remove it from the box.
1. Plug the AC charger into a wall outlet.
2. Connect the charger cable to the bottom of the Treo device. Make sure
the arrow on the connector is facing up, towards your Treo screen.
3. Wait for the indicator light to turn solid green. This may take up to
four hours.
