Ascent rate warning
The NiTek Plus 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, an audible alarm sounds for
three seconds 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.
PO2 limit warning
The PO2 warning indicates that you have exceeded the 1.4
atmospheres and/or 1.6 atmospheres for the gas you are
breathing. If you are using mix1 and exceed a PO2 of 1.4
atmospheres, an audible alarm sounds for three seconds, and the
PO2 value, PO2 symbol, and current depth blink. If you exceed a
PO2 of 1.6 atmospheres, in addition to the above audible and
visual alarms, the OLI bar graph flashes. If you are using mix2
and exceed a PO2 of 1.6 atmospheres, all visible alarms appear
and the audible alarm sounds twice.
