The Luna does not go into SOS until you go to the surface ( above 3' ) for more 3 minutes and neglect a mandatory Deco stop. At that point, you should stay out of the water, think about getting on O2 and heading to a chamber.
If you get back to depth in less than 3 minutes the Luna will not go in to SOS and you can clear your Deco.
If it does go into SOS, you can still go back to depth and use gauge mode.
I believe that if a Luna goes into SOS, the diver should stay out of the water in most cases.
You can always carry a 10' line, tie your computer to it & go have lunch while your dive computer clears the Deco. ( Not recommended! )
