24 NiTek Dive Computer User Manual
Note: Should the OLI and PO2 warnings activate at roughly the
same time—and at relatively shallows depths, early in the dive—
you most likely have not exceeded your actual oxygen limits.
What has happened, is that you forgot to set the FO2 percentages
prior to the dive and the computer has FO2 defaulted. See
“Understanding FO2 default” for more information.
OLI warning with the oxygen bar graph flashing
Decompression stop violation warning
A decompression stop violation warning takes place when you
ascend to a shallower depth than the indicated stop depth or if
you do not spend sufficient time at the required depth before
ascending. When you enter this violation, the computer’s audible
alarm sounds, and the stop depth, stop time, and “DECO”
flashes. These items continue blinking as long as you remain
shallower than the indicated stop depth.
Note: During a deco stop violation, the computer’s ascent rate
warning does not function.
Caution: If you do not correct an indicated deco stop violation,
the warnings continue for several minutes after surfacing. At this
point, the computer is not usable for the next 24 hours.
