Using the NiTek Duo

44 NiTek Duo Dive Computer User Manual

• Do not use the NiTek Duo when the “E” symbol is

displayed. This means that you are above an altitude of

19,685 feet (6,000 meters), which is beyond the NiTek

Duo’s ability to function accurately.

• Do not place the NiTek Duo in dive mode when making

sudden, substantial changes in altitude, such as when flying

in an airplane. This can be caused by storing the NiTek Duo

with wet dive gear, which can touch its external electrical

contacts and cause it to enter dive mode. This can interfere

with the computer’s ability to function accurately.

The NiTek Duo monitors and displays altitude information in all

modes, except PC transfer mode. Upon arriving at altitude, the

NiTek Duo’s residual nitrogen bar graph may show that there is

excess nitrogen present, even though you may not have made

any dives in the preceding 24 hours.

If you have obtained the altitude specialty diver training which

everyone should do before diving at altitudes substantially above

sea level, you already understand that this should be expected.

By ascending to a higher altitude from a lower one, your body

has more nitrogen saturated in body tissues than would be

present had you spent the preceding 24 hours at the higher

altitude. By displaying residual nitrogen and a surface interval,

your NiTek Duo is merely reflecting this fact.

If the level of residual nitrogen calculated by the NiTek Duo is

unusually high (seven or eight bars) when going to altitude, the

computer will be unable to enter dive mode. Avoid taking the

computer to altitude when residual nitrogen levels are this high,

and do not enter the water until nitrogen levels have dropped

substantially.
