Each time the unit is activated, FO2 will be automatically set for
a default value of AIR which can then be changed to values
between 21 and 50% in increments of 1%.
• While the Surface Sequence is scrolling, depress the button
for 2 seconds.
• Release the button when the FO2 screen appears with the
Set Point flashing (Fig. 18).
• Press/release the button repeatedly to increase the FO2
value from 21 to 50% in increments of 1%, then display AIR
again.
• For each FO2 value that appears, the display indicates the
Maximum Depth that can be achieved for a PO2 of 1.60
ATA (Fig. 19a), or the PO2 Alarm Set Point. If FO2 is set for
AIR, no Depth value will be displayed.
• Depress the button for 2 seconds to accept the FO2 Set Point
displayed and advance to the Set Wet Activation screen.
