Using the Surface Mode

The surface mode is used to display elapsed time from the end of the most recent scuba dive (S.I. time) and the amount of time remaining until boarding an aircraft is permitted (no fly time). * The surface mode is preferentially displayed at all times after scuba diving. * When the no fly time reaches 0 hours 00 minutes, the watch exits the surface mode , and returns to the time mode of the standard mode . The surface mode is not displayed after that time until completion of the next scuba dive. * If the watch is insufficiently charged (when the level of the charge level indicator is  ), in the lower left corner of the display in the surface mode changes to  to indicate that the watch should be charged.

Avoid traveling in an aircraft while the surface mode is activated. Traveling in an aircraft without allowing sufficient time to rest after diving results in the risk of decompression sickness. It is recommended to avoid traveling in an aircraft for at least 24 hours after diving whenever possible even if the surface mode is no longer displayed. There are no rules for completely preventing decompression sickness caused by flying in an aircraft after diving.
