PDA-Nulstilling

While holding down on the far left (calendar) and far right (iTask) press in on the reset button (reset hole) with your stylus for about 2-3 seconds. The Pocket PC should reset and power back on. If the device does not power back on, make sure that the battery lock switch is to the left (locked).
