If the menus are the same, the choices are AIR, NITROX, ON /OFF and if you toggle to OFF, this puts it in free-dive mode. If you go underwater, then its stuck in free-dive mode for 48 hrs.
I think that's how it works.
Hope this helps.
The FREE mode has a time limit of 10 minutes. After 10 minutes, Suunto D4i will automatically change from Free Dive to Scuba Bottom Timer. After the dive, the no- fly time will countdown from 48 hours. Also, you will not be able to dive in AIR or NITROX modes until the no-fly time has counted down to zero. You can only set the DIVE mode to OFF.
NOTE If you want to dive in AIR or NITROX mode after diving in FREE mode, remember to switch to the correct mode. Otherwise, the
free dive time limit will activate after 10 minutes.
