30DIVE SET 1 for RATIO iX3M Tech+ & iX3M RebTo navigate this menu follow the clues in the picture on the left.Algorithm: Select the decompressive algorithm you want to use for your dive.BUL: Bühlmann ZHL-16 BVPM: VPM-B (next page of this manual)If the chosen Algorithm is BUL:GFL/GFH: set the Gradient Factor Low (GFL) e Gradient Factor High (GFH).Attention: The GFL can NEVER be higher than the GFH.It is possible to set the GFH from 20% to 100% ( 20% < GFH < 100% )It is possible to set the GFL from 20% to GFH ( 20% < GFL < GFH )Do you know what?: You can keep pressed the buttons C or D to change the iX3M data more rapidly.ATTENTION: To change the Gradient Factor’s value a suitable theoreticalknowledge is needed.DO NOT CHANGE THE GRADIENT FACTOR WITHOUT HAVINGRECEIVED A SUITABLE TRAINING.The RATIO iX3M is not responsible for damages to people or objects due to a wrongsetting of such parametres.For suggested protection levels refer to the previous page of this manual.Do you know what?:If you have any doubts on your device’s setting, you can set the company’s parametres from the menu DEFAULTDo you know what?:Generally speaking, reducing the GFH involves a computer increasing conservatism. The GFL’s reductioninvolves a shift towards a major depth of the first compulsory decompressive stop.Do you know what?:With the RATIO iX3M it is possible to change the value GFL/GFH while diving, to manage possible emergencies.DIVE SETTINgSWATER:DIVE MODE:GFL/GFHALGORITHM:DECO CTRL:bA C DExIT NExTENTRY + _SALTSCUBA93/93BULONFor iX3M Tech+ iX3M Reb
