HIGH PO2 DIVE MODE
The DataPlus enters the High PO2 Dive Mode (Fig. 41) when partial pressure of
oxygen becomes equal to or greater than 1.40 BAR as indicated by the digital
display.
In the event that this does occur, the value of PO2 (Fig. 41a), and the symbol
'PO2' (Fig. 41b), will be displayed in place of Max Depth and Elapsed Dive Time
(if in the No Deco Dive Mode), or the required Stop Depth and Time (if in the
Deco Dive Mode). The PO2 value will remain on display until the partial pres-
sure of oxygen decreases below a value of 1.40 BAR.
In the event that you enter High PO2 Dive Mode, you must focus on reducing
the partial pressure of oxygen by slowly ascending to a shallower depth at a safe
rate. Oxygen Exposure, High O2, and High PO2 Dive Mode are more fully
described beginning on page 57 in the Handling the Extremes section.
VIOLATION MODES
The DataPlus enters one of three different Violation Modes (Conditional, De-
layed, or Immediate) when you exceed its ability to predict an ascent procedure.
Violation Modes are more fully described beginning on page 50 in the Handling
the Extremes section.
