Resetting the Surface Pressure
The device automatically determines the surface pressure using the barometric altimeter. Large pressure changes, such as during a flight, can cause the watch to automatically start a dive activity. If the watch starts a dive activity incorrectly, you can reset the surface pressure by connecting the watch to a computer. If you do not have access to a computer, you can reset the surface pressure manually.
