Calibrating the Barometric Altimeter

Your device was already calibrated at the factory, and the device uses automatic calibration at your GPS starting point by default. You can manually calibrate the barometric altimeter if you know the correct elevation or the correct sea level pressure.

  1. Hold UP.
  2. Select Settings > Sensors > Altimeter.
  3. Select an option:
    • To calibrate automatically from your GPS starting point, select Auto Cal. > On.

    • To enter a known altitude, select Calibrate.
