In altitude display mode, press the [SET] and [ALTITUDE/+] buttons simultaneously, and then [+] or [-] to change the altitude. In relative altimeter mode, the measured altitude is reset to zero, with the current position defined as the zero point (0 m). The relative altitude is then measured from this zero point. To reset the altitude to zero, press and hold the [ALTITUDE/+] button until "0 m" appears at the bottom of the screen. Then move around; the screen will now display the relative altitude. Press and hold the [ALTITUDE/+] button again to return to the display of the actual altitude.
