Using the NiTek Trio
34 NiTek Trio Dive Computer User Manual v1.2
When seven of the O2’s eight bars are displayed, the computer’s
audible alarm sounds for three seconds, and “OLI CAUT” (caution)
blinks on the upper display. If you do not ascend to a shallower depth,
and all eight of the O2’s bars are displayed, the alarm will sound again
and “OLI ALARM” blinks again. “OLI ALARM” continues to flash
until the O2 bar graph drops to seven bars. This warning will appear in
log mode after the dive.
If the OLI and PO2 warnings activate at roughly the same time—and at
relatively shallows depths, early in the dive—you probably have not
exceeded your actual oxygen limits. What is likely 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.
View 1 - OLI warning, “OLI CAUT” and “OLI ALARM” blinking.
