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

symbol, O2 segment of the O2 Bar Graph, and UP Arrow will
flash as a warning until PO2 decreases (Fig. 67).
