cressi archimedes 2 nitrox probmlems , OLI

[batman diver]

i went nitrox diving with my archimedes 2 today , 1st dive , 30 min , 34%02 and po1.4 , at the end of the dive my oxygen toxicity was 2 bars , on my second dive exactly 60 minutes after , as i went under it went mad , beeping and flashing , o2 toxicity went to full and it kept saying OLI , anyone know wats potting ?

Ok well I figured out wat was wrong , so in case this happens to some one else , when the archimedes does a nitrox dive , 10 min after the dive it puts the o2 to 100% , so u have to readjust it b4 the next dive , a safety feature I'm guessing.
