This is exactly what I wanted to find out eventhough my question wasnt exactly spot on.
When you say the history of the computer are you talking about:
how many hours of diveing in total?
how many dives in total?
This is the data you cannot erase?
How about the dive logs? Can I erase those? Or should I download them first and then it will clear itself?
Thanks again
Don't know mate, have never pressed the button. But it is in your best interest that you can't delete the history as otherwise how do you differentiate between a new and a used model? (Assuming covers were easily accessible)
A further reason (of dark nature) would be to be able to determine, without any shadow of doubt, what the diver was doing at the time of an accident.
Go ahead and press the button. You'll find what gets wiped and what doesn't very quickly.
