As above and its the same for the VR2. I have done this when I was inside a wreck and it asked for a stop that I couldn’t get back down for. It asks you to refer to tables but continues best guess deco. I continued to dive the unit two or three times a day for the next few days and the warning staid there but it worked fine. Surprisingly the warning gave up after a while despite the repeated diving.
I have no idea what happened to JBs computer but he either didn’t read the instructions (he is male after all

) or he had a faulty unit.
