High O2 during Deco
If a High O2 Warning (80%) occurs while at a Deco Stop, the graphic O2 will flash (in
place of Stop Depth/Time) until the Audible is silent, then Stop Depth/Time is restored.
If a High O2 Alarm (100%) strikes while at a Deco Stop, the graphic O2 and O2BG will
flash (in place of Stop Depth/Time and TLBG) until on the surface. The Up Arrow icon will
replace the Deco Stop icon (both arrows with bar) and flash until on the surface.
High O2 on Surface
The graphic O2 flashes (in place of NORM) and the full O2BG is displayed solid until O2
decreases below 100% (to 4 O2BG segments), then the NORM Surface Main screen is
restored.
If High O2 occurred during Deco, the graphic O2 flashes with the full O2BG solid for the
first 5 minutes, then the O2BG is removed and the graphic O2 alternates with VIOL until
O2 decreases below 100%, then the graphic O2 alternates with NORM until 24 hours
elapse with no dive.
> Operation enters VGM.
> In the event that a dive is made during the 24 hour period, a full 24 hour surface
interval must then be served before all functions are restored.
> During that 24 hours, VGM does not allow access to the Set F, Plan, Dsat, and FREE
Mode features/screens. All Watch and Compass functions will be allowed.
