exceed a limiting PO2 of 1.6 atmospheres, a series of horizontal
lines appears in place of the no-decompression limit.
To enter dive plan mode:
1. Press button A.
The arrow at the bottom of the display points to PLAN.
2. Press button A to increment the depth.
The no-decompression time limits change automatically
based on the depth.
3. When finished, press and hold button A for three seconds to
return to surface mode.
WARNING: Do not plan dives to depths deeper than those for
which the NiTek is capable of displaying an available no-
decompression limit. Doing so could cause you to exceed the no-
decompression limits or a limiting PO2 of 1.6 atmospheres. This
may increase your risk of decompression illness or CNS oxygen
toxicity and can lead to serious personal injury or death.
Setting the FO2 gas percentage
While in dive plan mode, you can set the FO2 gas percentage
that you are going to use on your dive. The FO2 gas percentage
can be set for air to 50 percent oxygen.
Note: It is important to check the FO2 gas percentage prior to
every dive to make sure the gas percentage programmed matches
the gas percentage you are using for the dive.
When you enter the FO2 set mode, the depth and NDL disappear
and the FO2 value flashes.
