xxx is shown on the display while calibration is being performed. When calibration is successful, the display will show OK and the Digital Compass Mode (showing the angle value) screen.

If xxx appears and then changes to ERR (error) on the calibration screen, it means that there is something wrong with the sensor. When ERR disappears after about one second, try performing the calibration again. If ERR keeps appearing, contact your original dealer or nearest authorized CASIO distributor to have the watch checked.
