Page 14: Getting Started
Using the NiTek Getting started The NiTek has many modes and screens and a number of options that can be changed depending on your dive location and profile. The following is a checklist of general things that you should pay attention to before, during, and after a dive. -
Page 15: Accessing Display Modes And Screens
Accessing other modes or screens requires the use of the NiTek’s buttons. Button operation The NiTek has two buttons (A and B), which are used to access the different modes and screens. To use the buttons, simply press the button once or hold the button down depending on what you are trying to do. -
Page 16: Surface Mode
Using the NiTek Surface mode Surface mode is the NiTek’s default mode. The computer returns to this mode automatically upon surfacing from a dive and from other modes when a period of time has passed without the buttons being pressed. -
Page 17: Setting The Time And Date
Setting the computer for metric or Imperial operation The NiTek can calculate and give you values in Imperial units or metric units. When in Imperial, depth values are expressed in feet and temperatures are expressed in Fahrenheit (°F). When in metric, depth values are expressed in meters and temperatures are expressed in Celsius (°C). -
Page 18: Dive Plan Mode
If the computer is in FO2 default, a series of horizontal lines appears. If the NiTek calculates that there is residual nitrogen present from previous dives, the available no-decompression limits are shorter. Depending on how much residual nitrogen is present, no NDL time may be displayed for some deeper depths. -
Page 19: Setting The Fo2 Gas Mix Percentage
Do not plan dives to depths deeper than those for WARNING: which the NiTek is capable of displaying an available no- decompression limit. Doing so could cause you to exceed the no- decompression limits or a limiting PO2 of 1.6 atmospheres. This may increase your risk of decompression illness or CNS oxygen toxicity and can lead to serious personal injury or death. - Page 20 3. When finished, press button A to return to dive plan mode. 4. To return to surface mode, press button A for three seconds.

(NDLs) or mandatory decompression stop information. Again, to do so, the NiTek must be set in a manner that accurately matches the concentration of nitrogen being breathed. When this information is not available, the NiTek attempts to protect divers by basing its oxygen- and nitrogen-exposure calculations on a “worst case”... - Page 22 NiTek’s alarm sounds and the O2 bar graph and PO2 Limit symbols flash. The computer’s ability to accurately monitor your exposure to oxygen no longer exists. You should not rely on the NiTek as the sole means of Note: tracking your exposure to elevated partial pressures of oxygen (PO2s).

Ascent rate warning The NiTek assumes that you keep your ascent rate within the following limits: Depth range Ascent rate 0 to 19 feet (0 to 5.9 meters)
- Page 27 PO2 limit warning with the PO2 LIMIT and depth flashing Oxygen limit index (OLI) warning The NiTek’s oxygen limit index (OLI) reflects the cumulative effect of your exposure to elevated partial pressures of oxygen. The PO2 warning only accounts for the intensity of the exposure, but the OLI accounts for both the intensity and length.

- Page 29 PO2, OLI and deco stop violations, and required decompression stops. For this reason, you should not, under any circumstance, use a NiTek in such a way that would cause an out-of-range warning. Under such conditions, the risk of serious personal injury or death would be substantial.

Page 33: Log Mode
Using the NiTek Log mode For each dive (up to ten total), the NiTek stores information, such as depth, time, temperature, etc. in a log. This stored log information can be viewed directly from the NiTek’s screen when in log mode. - Page 34 You can also press button B while on page two to scroll through the logged dives. 4.

Altitude rank symbols... - Page 39 (6,000 meters), which is beyond the NiTek’s ability to function accurately. • Do not place the NiTek 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 with wet dive gear, which can touch its external electrical contacts and cause it to enter dive mode.
