Hard Reset:
With the unit turned off, press and hold the follow buttons: PAGE + Enter on the click stick. Then press and release the POWER. The unit will power up asking if you want to release all user data. Select yes, and the unit will be reset. After the master reset, place your unit outside, so that it has a clear view of the sky for 25 to 30 minutes for the unit to acquire new almanac data.
Dit klopt, maar het toestel moet wel eerst opstarten. En dat is nou net het probleem. Dat wil hij niet!
