I have a oceanic VEO 200 that has been with me for 6 years without a problem in till 2 weeks ago while in the middle of a dive the screen went blank then the words DEMO MFT showed up on the screen. I removed the old battery for 6 days then replaced it with a new one & DEMO MFT is still on the screen & it will not allow me to excess any of the info. (locked out) what can I do, what is this DEMO MFT?
