ReACT Pro
OXYGEN EXPOSURE
The ReACT Pro is a sophisticated instrument designed with capabilities that go beyond the range
of recreational diving with compressed air. It will help you to avoid and manage excessive oxy-
gen exposure.
Refer to the Reference section of this manual for additional information.
PARTIAL PRESSURE OF OXYGEN
As depth increases during a dive, the partial pressure of oxygen (PO2) increases. The current
Level of PO2 (Fig. 63a) may be viewed by pressing the LEFT button 1 time to access the Alter-
nate #1 Display.
High PO2 Dive Mode
The ReACT Pro enters the High PO2 Dive Mode when PO2 becomes equal to, or greater than,
1.40 ATA , as indicated by the UP Arrow and symbol PO2 appearing on the display (Fig. 64) un-
til PO2 decreases below a value of 1.40 ATA. The Audible Alarm emits one Beep per second.
If partial pressure of oxygen continues to increase, the value of PO2 will increase toward a maxi-
mum value of 5.00 ATA in increments of '.01' ATA.
When PO2 reaches a value of 1.60 ATA , the UP Arrow, NITROX, and PO2 symbols will flash as
a warning (Fig. 65). The Audible Alarm emits one Beep per second. When PO2 decreases be-
low 1.60 ATA, the flashing will stop.
