Warnings while in diving mode
While in diving mode, there are several warnings that you should be
alert to.
Default warning
If any mix is in default at the beginning of a dive, an audible alarm
sounds for three seconds. If you ascend and set the mix percentages,
you can restart the dive. The upper display also blinks “WATER SET
FO2!”, which is the best indication that the computer is defaulted
before entering the water.

Ascent rate warning
The NiTek Trio 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, “SLOW” and the current depth flash
for six seconds and an audible alarm sounds for three seconds. 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.
