• The Air option will not be displayed in Set FO2 for Gas 1 until a full 24 hour Surface
Interval has elapsed.
• If the FO2 50% Default is set Off, FO2 remains at the values set until changed. If the
Default is set On, all FO2 values default to 50%.
• The OC1 is programmed to prevent FO2 Gas 2 and 3 from being set at values lower
than the FO2 Set Point for Gas 1. Gas 2 and Gas 3 require Set Points equal to/
higher than Gas 1 and Gas 2, respectively.
DIVE TIME REMAINING (DTR)
The OC1 constantly monitors No Deco status, O2 Accumulation, and Air Time Remain-
ing (when TMTs are used), and will display whichever Time is the least amount available
as DTR on the No Deco Dive Main screen (Fig. 71). The graphic NDC, OTR, or ATR will
identify the Time displayed. If ATR is DTR, it will not be displayed at the lower/left.
No Deco DTR (NDC)
NDC is the maximum amount of time that you can stay at your
present Depth before entering Deco. It is calculated based on
the amount of Nitrogen absorbed by hypothetical tissue com-
partments. The rates each of these compartments absorb and
release Nitrogen is mathematically modeled and compared
against a maximum allowable Nitrogen level.
Whichever one is closest to this maximum level is the controlling
compartment for that Depth. Its resulting value will be displayed
NDC time (Fig. 71a) and graphically as the TLBG (Fig. 71b).
