sity, dehydration, cold or exertion, which experts believe place divers at greater risk

of DCI. If these, or similar factors apply to you, use the NiTek He—and other

dive computers or dive tables—with even greater caution.

 Experts still know surprisingly little regarding the exact nature and causes of decom-

pression illness (also known as decompression sickness, DCI or DCS). Susceptibility

to DCI may vary substantially from person to person and from day to day. Neither

the NiTek He—nor any other dive table or computer—can guarantee that you will

not suffer decompression illness. Even though you use these items correctly, you

may still suffer DCI. Use your NiTek He conservatively, and in conjunction with

other dive planning devices, such as dive tables. Do not rely on the NiTek He, or any simi-

lar device, as your sole means of avoiding decompression illness.

Using Your NiTek He

The NiTek He is capable of presenting far more data than can t in a single display

screen. Thus, to help avoid confusion, it presents only that data which is relevant to

a particular situation. These different data screens are called display modes.

The NiTek He will enter its Surface and Dive modes automatically. To access

other display modes, you must push the orange buttons on the NiTek He’s face.

These are the A and B buttons.

The accompanying ow chart will tell you which buttons to push, and in

which sequence, to access a particular display mode. (Note that you cannot enter any

mode other than Surface mode within ten minutes of surfacing. )

Gauge mode is a state in which the NiTek He tracks depth, time and tempera-

ture data, but does not compute the effect of exposure to elevated levels of oxygen,

helium and nitrogen. While in this mode, the word GAGE appears above the mode

indicator. This is the mode you would choose to use if diving below 394 feet/120

meters (past which the NiTek He cannot function as a dive computer), and using

dive tables as your primary dive planning and inert gas exposure tool. In Gauge

mode the NiTek He will function to a depth of 656 feet/200 meters. How to switch

from dive computer mode to Gauge mode is shown on the ow chart.

Surface Mode

Surface mode is the NiTek He’s default mode. The computer returns to this mode

automatically upon surfacing from Dive mode, and from other display modes after

two to three minutes of inactivity. You can also access Surface mode from other dis-

play modes by holding button A for two to three seconds.
