OCi OPERATING MANUAL

Doc. No. 12-5335-r02 (9/12/13)

If PO2 continues to increase and reaches the Alarm setting for the gas in use, the Audible sounds again during which the graphic
UP with Up Arrow icons will fl ash, and the PO2 value with icon will fl ash (in place of Pressure) until the Audible is silenced (Fig.
92).

After the Audible is silenced by pressing S or 10 seconds elapse, PO2 will alternate with Pressure until PO2 decreases below
the Alarm level, then Pressure will be restored with PO2 removed.

The graphic UP and Up Arrow icons remain on fl ashing until PO2 decreases below the Alarm level, then they are removed.

High PO2 during Deco

When in Deco, PO2 will only alarm at 1.60, regardless of the Gas in use and the PO2 alarm value set for that Gas. There is
also no warning given.

> When PO2 reaches 1.60, the Audible will sound during which the PO2 value (1.60) with icon will fl ash in place of Pressure

(Fig. 93).

> When the Audible is silenced, PO2 will alternate with Pressure until PO2 decreases below 1.60 at which time Pressure will

be restored and the PO2 information removed.

HIGH O2

Warning >> at 80% (240 OTU for a dive or day).
Alarm >> at 100% (300 OTU for a dive or day).

High O2 during No Deco

Upon activation of the Warning (80%), the Audible will sound during which the % of O2 will fl ash in place of DTR (NDC or OTR)
(Fig. 94).

> Pressing S (< 2 sec), or after 10 seconds elapse, will silence the Audible.
> When the Audible is silenced, DTR will be restored.

If O2 increases to the Alarm level (100%), the Audible will sound again and the O2 value with graphic O2 SAT will replace DTR
(Fig. 95) until on the surface.

High O2 during Deco

If a High O2 Warning (80%) occurs while at a Deco Stop, the Audible will sound during which the % of O2 will fl ash in place of
Stop Depth/Time (Fig. 96).

No indication will be given to ascend which is your decision based on activity at the time.

> Pressing S (< 2 sec), or after 10 seconds elapse, will silence the Audible.
> When the Audible is silenced, Stop Depth/Time will be restored.

If O2 increases to the Alarm level (100%), the Audible will sound again, the O2 value with graphic O2 SAT will replace Stop
Depth/Time, and the graphic UP with Up Arrows will fl ash until on the surface (similar to Fig. 95).

O2 Alarm after Surfacing

If O2 is 100% upon surfacing while in No Deco, 100% O2 SAT will be displayed fl ashing in place of the graphic NORM and
the algorithm graphic (Fig. 97) until 10 minutes elapse, then it will alternate with them until O2 decreases below 100% when the
NORM Surface Main will be restored.

If O2 is 100% upon surfacing while in Deco, 100% O2 SAT will be displayed fl ashing in place of the graphic NORM and the
algorithm graphic (similar to Fig. 97) until 5 minutes elapse, then operation will revert to Violation Gauge Mode.
