  1. Hold MENU.
  2. Select Settings > Sensors & Accessories > Altimeter.
  3. Select an option:
    • To calibrate automatically from your GPS starting point, select Auto Cal..
    • To enter the current elevation manually, select Calibrate > Enter Manually.
    • To enter the current elevation from the digital elevation model, select Calibrate > Use DEM.

    NOTE: Some watches require a phone connection to use DEM for calibration.

    • To enter the current elevation from your GPS location, select Calibrate > Use GPS.
