DECOMPRESSION MODEL
The programs within the DataTrans Plus simulate the absorption of nitrogen into the body by using a mathematical model. This model is
merely a way to apply a limited set of data to a large range of experiences. The DataTrans Plus dive computer model is based upon the
latest resear ch an d experiments in decompression theory. Still, using the DataTrans Plus, just as using the U.S. Navy (or other)
No Decompression Tables, is no guarantee of avoiding decompression sickness, i.e. “the bends.” Every diver’s physiology is
different, and can even vary from day to day. No machine can predict how your body will react to a particular dive profile.

Module and a radio frequency Transmitter that will be installed into a high pressure port of your regulator
fir st stage, or is built into an Ocean ic DX3™ Integrated first stage regulat or. The transmitter sends tank pres-
sure data to the display module via a low frequency signal. In addition to nitrogen and oxygen loading data,
breat h in g gas con su m pt ion is calcu lated an d displayed in gr aphic an d alph a/n u m er ical for m at s on th e
computer’s scr een . Th e Display Module can also be used wit h out the t r ansmit ter as a stan d alon e, non-int e-
grated computer, and will retain full use of all functions except those that related to tank pressure.

dives using Oceanic's intuitive combination of easy to read displays and unique identification icons. Tissue
loading of nitrogen, accumulation of oxygen, ascent rate, breathing gas consumption rate, and breathing gas
time remaining are presented as segmented bar graphs alongside color coded reference indicators that bring
quick focus to these important status displays.
As you pr ogr ess t h r ou gh t h is in st r u ct ion a l gu ide, you will becom e fa m iliar wit h a ll of t h e u n iqu e fu n ct ion s an d
features available an d see examples of th e displays t h at you could expect to see in the var ious operat ion al
modes. Refer to the Glossary of terms on page 121, and keep the waterproof Review Card handy during your
dive trips. Although it will require an initial investment of time to become acquainted with the various icons

DataTrans Plus
and bar graphs of the Graphic Diver Interface, you’ll soon agree that the DataTrans Plus is easy to under-
stand and use.
The DataTrans Plus has a wide array of features described in detail throughout the pages that follow. Due to
the importance that they be understood thoroughly prior to using the DataTrans Plus, information will be ex-
panded upon and some refreshed as you proceed. Relax and read through the complete guide.
It is extremely important that you:
• Read this owner's guide in sequence and understand it completely before attempting to use
the DataTrans Plus.
• Check the DataTrans Plus frequently during your dive.
• You must also be a trained diver,certified by a recognized training agency in Scuba diving.
• Prior to using the oxygen related features of the DataTrans Plus,you must also be trained
and certified for diving with enriched nitrogen-oxygen (nitrox) mixtures by a recognized
training agency.
Remember that the rules you learned in your basic scuba certification course still apply to the diving you will
do while using a dive computer - some will become even more important. Technology is no substitute for com-
mon sense, and a dive computer only provides the person using it with data, not the knowledge to use it.
Be a RESPONSIBLE DIVER at all times.

INTERACTIVE CONTROL CONSOLE
The DataTrans Plus is a unique dive computer with interactive controls that
allow you to select various display options and access specific information
when you choose to see it. The Interactive Control Console consists of the Ad-
vance (Left) button and Select (Right) button (Fig. 1).
The control buttons can be pressed repeatedly, releasing upon hearing a beep,
or held in to scroll and continue as you set or access different display modes.
On the surface, before diving, you can perform the following operations using
the Control Console:
• Activatethedisplaymodule
• Select unitsofmeasure-English or Metric
• Select MessageBox™language-English,Italian,German,Spanish,or
French
• Set depth &gasalarm warninglevelSet Points™

• FO2 mode - to program the percentage of oxygen in the nitrox mix.
• Plan mode - to view no decompression limits and plan your next dive.
• Log mode - to view data from your 12 most recent dives.
• History mode - to view the total number of dives, maximum depth, etc.
• Set mode - to establish prefered selections.
• External Access mode - to download (copy) dive data from the
Dat aTr an s P lu s t o a u nique P C log/pr ofile pr ogr am .
During the Dive mode, the Advance (Left) button can be used to activate the
display's Oceanglo™backlight, and the Select (Right) button can be used to ac-
cess an Alter nat e Dive mode, that displays additional information including
maximum depth, bottom time and temperature.
INFORMATIONAL DISPLAYS
Operational modes and status information is visually represented numerically
an d/or gr aphically and can be un derstood at a glan ce wit h t h e aide of un iver sal
icons (Fig. 2) that identify and bring quick focus to the displays. Also, segmented
bar graphs will show how close you are to critical limits.
In critical situations, a Message Box™flashes urgent messages, while an au-

dible alarm sounds to alert you to check this information. These concise,
simple messages (Fig. 3), such as “TOO FAST” or “TOO DEEP" are displayed
in the language that you choose during setup.
Each DataTrans Plus numeric and graphic display represents a
unique piece of information. It is imperative that you understand
the formats, ranges, and values of the information represented to
avoid any possible misunderstanding that could result in error.
NOTE: Throughout this owner's guide reference is made to the
term 'breathing gas'. The rational being that the DataTrans
Plus can be used for 'air'dives or 'nitrox'dives. For clarity
these terms are defined as -
Breathing Gas - the gaseous mixture breathed during a dive.
Air - a breathing gas that contains approximately 21% oxygen
and 79%nitrogen (nature's common nitrogen-oxygen mixture).
Nitrox - a nitrogen-oxygen breathing gas that contains a higher
fraction of oxygen (22 to 50%) than air.
UNIVERSAL GRAPHIC DIVER INTERFACE ™
Five bar graphs referred to as the Universal Graphic Diver Interface™ appear
around the perimeter of the DataTrans Plus screen (Fig. 4). These segmented

bar graphs are located next to green, yellow, and red color coded portions of the
peripheral decal that denote normal, caution, and danger zones, respectively.
When u n derwater, you can quickly focus on t he bar graph s t o make sure t h at
they are in the green. You can quickly verify that you're not getting too close
to the no decompression limit or the oxygen tolerance limit, or ascending too
fast , or con sum ing breathin g gas too fast , or r un n ing low on breathin g gas.
Tissue Loading Bar Graph™
The Tissue Loading Bar Graph™ represents nitrogen loading (Fig. 5), showing
your relative no decompr ession or decompr ession status. As your depth and
elapsed dive time increase, segments will add to the graph beginning in the
lower left portion of the screen. As you ascend to shallower depths, this bar
graph will begin to recede, indicating that additional no decompression time is
allowed for multilevel diving.
The Tissue Loading Bar Graph monitors 12 different nitrogen compartments
simultaneously and displays the one that is in control of your dive. It is divided
into a green No Decompression zone (NO DECO), a yellow Caution zone (C.Z.),
and a red Decompression zone (DECO). The bar graph gives a visual represen-
tation of just how close you are to the no decompression limit with a yellow
Caution (C.Z.) Zone.
This Caution Zone portion of the bar graph (Fig. 5a) allows you to make a deci-
sion regarding safety stop duration or necessity. While you cannot provide a

guarantee against the occurrence of decompression sickness, you may choose
your own personal zone of caution based upon age, physique, excessive weight,
etc., to reduce the statistical risk.
The Tissue Loading Bar Graph assists you with managing decompression by
fillin g a large red 'ceiling st op required' segmen t (F ig. 5b). Decompression is
explained in detail in the Handling the Extremes section.
Prior to a repetitive nitrox dive, if all segments of the Tissue Loading Bar
Graph are displayed during the Pre Dive Planning Sequence™, and no seg-
ments of the O2 bar graph are displayed (Fig. 6), that next dive is calculated to
be controlled by nitrogen loading.
