per minute in place of Stop Depth/Time until PO2 is less than the
PO2 Alarm Set Point.
Upon surfacing the O2 graphic will flash for the first 5 minutes
(Fig. 88A), then it will alternate with the graphic Vio (Fig. 88B)
until O2 decreases to < 300 OTU, then Vio will alternate with
the graphic Nor. Operation will lock into NOR Mode, blocking
access to GAU and FRE, until the O2BG recedes to 4 segments.
