If PO2 continues to increase, the value displayed on the ALT 2 screen will increase in
increments of 0.01 (ATA) to a maximum value of 5.00 (ATA).
When PO2 reaches the PO2 Alarm Set Point, the Audible Alarm will sound again (10
seconds).
> The graphic PO2 and UP Arrow will flash as a warning until PO2 decreases below
the Alarm Set Point.
 The PO2 value can be viewed by pressing/releasing the A (Top) button 2 times to

HIGH O2
The O2BG (Oxygen Accumulation Bar Graph) displays either
oxygen accumulated during that Nitrox dive, or during the
repetitive dives you conduct during a 24 hour period, whichever
of the two is greater at that time. The O2BG lets you monitor
how close you are coming to the limits of oxygen exposure.
If the theoretical amount of oxygen accumulated equals, or
exceeds, 80% (240 OTU) of the limit for a single exposure, or
the exposure limit for a 24 hour period, the Audible Alarm will
sound (10 seconds), the UP Arrow and graphic O2 will come
On flashing (Fig. 87). After the Audible stops (10 seconds), the
O2 graphic will stop flashing. The UP Arrow will remain On
flashing until you surface.
