Handspring Treo 600 - Manual (Page 132)

Hard reset
A hard reset erases all data and third-party software on your Treo. Never
perform a hard reset without first trying a soft and system reset. You can
restore previously synchronized data with the next HotSync operation.
A hard reset can tell you whether a problem stems from your Treo or an
application installed on it. If you do not experience the problem after you
perform a hard reset, the problem may be related to software you installed.
See page 145 for suggestions on diagnosing third-party software issues.
1. Unscrew the stylus tip to access the reset tool.
2. While holding the Wireless Mode button
, use the reset tool to gently
press the reset button on the back of your Treo.
3. When the Palm Powered logo appears, release the Wireless Mode
button .
4. When the warning appears, press Up to confirm the hard reset.
5. If a language selection screen appears, select the same language you
selected for your desktop software.
