Fig. 67 - PO2 Alarm
When partial pressure of oxygen (PO2) becomes equal to, or greater than, 1.40 ATA, or 0.2 ATA less than the PO2 Alarm set point (a user setting); the red LED warning will flash, the Audible Alarm will sound (unless set OFF), and the current PO2 value, PO2 symbol, O2 segment of the O2 Bar Graph, and UP Arrow will appear on the Main Display as a warning until PO2 decreases. Current Depth and Dive Time Remaining will also be displayed (Fig. 66).
If PO2 continues to increase, the value displayed will increase toward a maximum value of 5.00 ATA in increments of .01 ATA. When it reaches a value of 1.60 ATA, or the PO2 Alarm set point (a user setting), the Audible Alarm will sound (unless set OFF) and the current PO2 value, PO2 symbol, O2 segment of the O2 Bar Graph, and UP Arrow will flash as a warning until PO2 decreases (Fig. 67).
