8 introduction welcome to oceanic and thank you for choosing the veo 180nx ! It is extremely important that you read this operating manual in sequence and understand it completely before attempting to use the veo 180nx. It is equally important that you read the oceanic dive computer safety and refer...
9 bar graphs tissue loading bar graph (tlbg) the tissue loading bar graph (fig. 1a) represents tissue loading of nitrogen, showing your relative no decompression or decom- pression status.
