Default Warning
If the computer is in default mode or set to a hypoxic mix at the
beginning of a dive, the backlight will flash. If you ascend and
set the mix percentages, you can restart the dive. See
“Understanding Default Mode” for more information.
Ascent Rate Warning
The NiTek X 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 58 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, “SLOW” flashes on the screen
and the backlight flashes. The warning displays until you slow
your ascent to an acceptable rate or you reach 5 feet (1.5 meters).
