(5) Nitrogen (N2) bar graph: All nine bars are displayed,
indicating that you are at or have exceeded the no-
decompression limits and have entered decompression.
Default warning
If the gas mix is in default at the beginning of a dive, an audible
alarm sounds and the O2 bar graph and PO2 LIMIT symbols
flash. If you ascend and set the mix percentage, you can restart
the dive.
Ascent rate warning
The NiTek assumes that you keep your ascent rate within the
following limits:
Depth range Ascent rate
0 to 19 feet (0 to 5.9 meters) 26 feet (8 meters) per minute
20 to 59 feet (6 to 17.9 meters) 39 feet (12 meters) per minute
59 feet (18 meters) or deeper 52 feet (16 meters) per minute
If you exceed these ascent rates, an audible alarm sounds and
“slow” is displayed and flashes on the screen. The warning
displays until you slow your ascent to an acceptable rate or you
reach 5 feet (1.5 meters). If the ascent rate is violated twice, the
“slow” symbol appears in log mode after the dive.
