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.

1. Hold until the watch turns off.
2. Hold to turn on the watch.
3. When the product logo appears, hold until you are prompted to reset the surface pressure.
