OC1 OPERATING MANUAL

FO2 set to Air

The default FO2 Gas 1 each new dive period will be Air. When FO2 Gas 1 is set for Air, calculations are the same as when

FO2 is set for 21%. When FO2 Gas 1 is set for Air, it will remain set for Air until set for a numerical FO2 value (21 to 50%).

When FO2 Gas 1 is set for Air, the O2BG will not be displayed at any time during the dive, on the surface, or during the PDPS.

PO2 will not be displayed during the dive.

MOD will not be displayed on the FO2 set screen when Air is displayed.

Internally, the OC1 will keep track of the oxygen loading so that if FO2 for Gas 1 is subsequently set for Nitrox, the oxygen load-

ing for previous Air dives will be accounted for in the next Nitrox dive (during that dive period and series of repetitive dives).

FO2 set for Nitrox

When FO2 for any Gas is set for a numerical value, the dive is considered Nitrox and the Nx icon will be displayed.

Once FO2 Gas 1 is set for a numerical value (21 to 50%), the Air option is disabled until 24 hours elapse after the last dive.

• 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 Remaining (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 compartments. 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).

As you ascend, the TLBG segments will recede as control shifts to slower compartments. This is a feature of the Decompression

Model that is the basis for Multilevel Diving, one of the most important advantages that Oceanic dive computers offer.

O2 DTR (OTR)

When the OC1 is set for Nitrox operation, O2 accumulation during a dive, or 24 hour period, is dis-

played as the O2BG on an ALT screen (Fig. 72a). As time remaining before reaching the O2 Exposure

Limit decreases, segments are added to the O2BG.

When the amount of time remaining before reaching the O2 Limit becomes less than the NDC, calculations for that Depth will be

controlled by O2 and OTR will be displayed as DTR on the Main.

Air Time Remaining (ATR)

The OC1

calculates ATR using a patented algorithm that is based on a diver's individual Air Consumption Rate and Current

Depth.

Tank Pressure is measured once each second and an average rate of Consumption is calculated over a 90 second period. This

Rate of Consumption is then used in conjunction with a knowledge of the Depth dependence to predict the Air required for the

diver to make a safe controlled Ascent including the No Deco Deep and Safety Stops and any required Deco Stops.

Air Consumption and Depth are continuously monitored and ATR reﬂects any change in circumstances. For example, when a

buddy starts breathing from your Octopus or you suddenly ﬁnd yourself swimming against a strong current and begin breathing

more rapidly, the OC1 will recognize the change and adjust ATR accordingly.

ATR is the time you can remain at the present Depth and still safely surface with the Tank Pressure reserve that you selected during

setup (End Pressure Alarm Setting).

ATR is displayed on the NORM No Deco and GAUG Main, and Deco ALT screen, when <= 60 minutes (Fig. 73a).

ATR Alarm

When ATR decreases to 5 minutes, the Audible will sound and the ATR Time digits will ﬂash (Fig. 74). If it decreases to 0, the

Audible will sound again. The digits will continue to ﬂash until ATR becomes greater than 5 minutes.

You should initiate a controlled Ascent while monitoring Tank Pressure. However, there is no reason to panic, the OC1 has

allowed for the Air necessary for a safe Ascent including the No Deco Deep and Safety Stops, if set On, and any Deco Stops

required.
