On Windows Mobile 5.0 products, a hard (full) reset stops all running programs, but does not clear user data or applications because they are stored in ROM (Persistent Store feature). A hard reset also resets all hardware registers. Users can perform a Clean Reset, in which the product is cleared to its factory defaults. A clean reset returns the HP iPAQ to the default Windows Mobile 5.0 settings with no user data or applications.

To perform a clean reset please follow these steps:

1. Press and hold the Calendar button, the Power button, and the Messaging button.
2. While holding these buttons, use the stylus to lightly press the Reset button on the bottom of the HP iPAQ
