I appreciate all of your concern over my going to the chamber. Yes the computer won't know my nitrogen loading, but I will! Why does everyone assume I won't?
The problem is that my last dive of the day ended around noon, and my first dive in the morning will be at 8:30. 24 hours will not have elapsed, and if I use my computer the 24 hour clock starts over again. The problem will continue until the end of my trip. Only thing I can do is dive without my computer tomorrow and then use it the next day - hmmm guess I can't do that because my computer won't know what my nitrogen loading is.
I understand why it's there, and I'm sure that there are some people out there that would get themselves into trouble, but there are also people that do know what they are doing. I think this is more about protecting the manufacturer from liability and is a PITA for the rest of us.
I'd have to question how the computer got into gauge mode to begin with.
To the rest of us that are familiar with that computer it sounds like you had a violation that caused it to go into that mode or you just used it in gauge mode without being fully familiar with the computer. If that is correct and you are trying to take it out of gauge mode, then I would suggest that maybe you are not really aware of what you are doing and the safety involved otherwise the computer wouldn't be in gauge mode to begin with.
