My Garmin Descent Dive Computer is Stuck in Dive Mode

There might be few circumstances where the Descent™ Dive Computer could initiate starting a dive. If this occurs, the Descent computer will no longer show the watch face but instead will display only the dive screens and in addition the back button will be disabled. To address this, we can reset the surface pressure.
