Using the NiTek Plus

the FO2 settings for mix1 and mix2. Make sure they accurately
match what you are going to breathe during the dive.
When the computer is in FO2 default mode, the Nitrox symbol
flashes. This indicates that you need to set the percentages for
mix1 and mix2 to the correct FO2.
If you go diving when the computer is in FO2 default mode, the
OLI and PO2 symbols, current depth, and PO2 value flash. The
computer’s ability to accurately monitor your exposure to
oxygen no longer exists.
Note:
You should not rely on the NiTek Plus as the sole means
of tracking your exposure to elevated partial pressures of oxygen
(PO2s). It is recommended that you use either a second Nitrox-
capable computer or another tracking method, such as Nitrox
tables.
Using gauge mode
If you do not want to use the NiTek Plus as a normal “dive
computer,” the NiTek Plus has a gauge mode. Gauge mode is
when the NiTek Plus is operating simply as a depth gauge and
bottom timer. “Gage” is displayed on the screen and exposure to
nitrogen and oxygen and no-decompression limits are not
tracked and no bar graphs are displayed. This mode is used by
divers who are relying solely on dive tables for decompression
information. The operating depth limit when in gauge operation
is 656 feet (200 meters).
Note:
You cannot select gauge operation if the computer
calculates that there is still residual nitrogen remaining from a
previous dive. Also, you cannot return to dive computer
operation until 48 hours have passed since your last dive.
