Warranty does not extend to plastic gauge face, rubber strap, o-rings, batteries, transmitter fitting corrosion, chrome loss, or damage due to accident, abuse, modification, or tampering.

DECOMPRESSION MODEL

The programs within the DataTrans 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 dive computer model is based upon the latest research and experiments in decompression theory. Still, using the DataTrans, 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, it even varies from day to day. No machine can predict how your body will react to a particular dive profile.

FEATURES

OVERVIEW

INTRODUCTION

Welcome to Oceanic and thank you for choosing DataTrans! We feel that

your new DataTrans will surpass your highest expectations as you become familiar

PSI

with its broad assortment of features and unique, interactive capabilities that give it the distinction of being a personal diving computer.

The complete DataTrans is a two component, air integrated system that consists

of a computer 'display module' and a Radio Frequency (R/F) 'transmitter' that will be installed into a high pressure port of your first stage, or is built into an Oceanic DX-2™ Integrated first stage. This transmitter continuously “sends” air supply data to the display module via a low frequency signal. In addition to no-decompression/ decompression status, air consumption is then calculated and displayed in graphic and alpha/ numerical formats on the computer’s screen - all without the use of wires or hoses!

The computer module can also be used without the transmitter as a “standalone,” non air-integrated computer, and will retain full use of all functions except those that are air related. It can therefore be purchased separately, and a transmitter can be added at any time in the future to make full use of the DataTrans' available features.

If navigating through the various modes of the DataTrans’ menu system seems complicated at first, relax. As you read through this Instruction Guide, you will see that the mode settings are actually easier to understand and perform than those of

most digital wrist watches. Refer to the icon legend and menu structure chart on the following pages, 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 and bar graphs of the Graphic Diver Interface, you’ll soon agree that the DataTrans is amazingly easy to use, and intuitively simple to understand - at a glance! After all, why spend any more time than necessary studying a computer screen, when there are far more interesting things to look at underwater?

The DataTrans has a wide array of features that are described in detail

throughout the following pages. It is extremely important that you read this

manual in sequence and understand it completely before attempting to use the DataTrans. Check the DataTrans frequently during your dive.

You must also be a trained diver, certified by a recognized training agency.

Remember at all times: The rules you were taught in your basic, open water

certification course still apply to the diving you will do while using a dive computer

- some will become doubly important. Technology is no substitute for common sense, and a dive computer can only be as smart as the person using it.

Be a RESPONSIBLE DIVER at all times.

OVERVIEW OF FEATURES

The DataTrans is very unique among diving computers presently available, due to its powerful interactive features that allow you - the user - to select various display options, and to access specific information you need, when you choose to see it. The key to these features is the Interactive Control Console, which consists of the ADVANCE button and SELECT button (Fig. 1). On the surface, prior to entering the water, these controls allow you to preset the following display options:

• Units of Measure - Imperial or Metric

• Message Box™ Language - English, Italian, German, Spanish, or French

• Custom Depth & Air Warning Set Points™

• Date & Time

• Link - Display Module to a Transmitter

You may choose to set these options only one time and leave them at those settings, or you may set them at different values any time while on the surface.

The controls can be pressed repeatedly , releasing upon hearing a beep, or held in to scroll and continue as you set or access different display modes that you choose. On the surface, you may select the Plan mode to plan your next dive, or choose the Log mode with time and date stamp to access your 12 most recent dives. A History mode displays the unit's complete history, including total number of dives, maximum depth, etc. After the DataTrans enters Dive mode underwater, the ADVANCE button may be used to backlight the display, and the SELECT button used to access an Alternate Dive mode, which displays additional information including maximum depth, bottom time and temperature (Fig 2).

Kg/Cm

One of Oceanic’s primary design objectives for dive computers has always been to display information in a format which is as easy to read and understand as possible, without any clutter of unnecessary information that may cause confusion for the diver. Until now, this has been accomplished by alternately showing primary and secondary screens of information at preset intervals. This allows the numerical figures for each display to be as large and as easy to read as possible, but it comes with the small inconvenience of sometimes waiting until the screen containing the desired information appears.

The DataTrans offers the best of all worlds, and transcends many language barriers. With the use of universal icons and four different bar graphs that make up the Universal Graphic Diver Interface (Fig. 3), information is visually represented and understood at a glance, minimizing the need for numerical displays. Underwater, the Control Console allows you to access an alternate display of information containing max depth, bottom time, and temperature, with the touch of a button - whenever you choose.

In a critical situation, however, icons, bar graphs, and numeric displays may not be enough to convey an urgent message. The Message BoxTM is an alpha/numeric display which flashes concise, simple messages, such as “TOO FAST,” or “AIR ALARM,” while the audible alarm simultaneously sounds to alert you to check this information. Most incredibly, these messages can be displayed in one of five language preferences that you choose, using the interactive Control Console before you enter the water.

Fig. 4 - Bar Graph Displays

Color Coded Bar Graph Displays

The Graphic Diver Interface contains four separate bar graphs that are each color

coded green, yellow, and red, and can be interpreted the same as a traffic signal.

The Tissue Loading Bar Graph® (TLBG) represents (Fig. 4a) nitrogen loading, showing your relative no-decompression or decompression status. As your depth and bottom time increase, segments will fill the graph from left to right. 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 TLBG also assists you with managing decompression by indicating four “ceiling” depths. This is explained in detail in the “Handling the Extremes” section.

The Variable Ascent Rate IndicatorTM (VARI) bar graph (Fig. 4b) shows you how fast you are ascending, rather than just showing that you are ascending too

FT M

fast. You can think of it as an ascent rate speedometer.

The Air Time Remaining™ (ATR) bar graph (Fig. 4c) provides a graphic

representation of Air Time Remaining, which represents the time that a diver can remain at his present depth and then, following a safe ascent, surface with a predetermined air reserve (e.g., 300 psi). This calculation and display is based on the diver's individual air consumption rate that is continually monitored by the

required decompression stops.

The Air Consumption Indicator™ (ACI) bar graph (Fig. 4d) is a true biofeed-

DataTrans, and it takes into account the air required for a safe ascent including any

back monitor that indicates your current breathing rate as compared to your personally established breathing parameters. The comparison is based upon an average rate established during the first 70 seconds of breaths.

While underwater, you must check each of these four bar graphs on a frequent basis. Oceanic strongly recommends that every effort should be made to keep each display “in the green” at all times to minimize any possibility of decompression sickness or an out-of-air situation. More detailed information regarding these displays is provided in the following sections.

In addition to it's unique interactive abilities, the DataTrans is fully loaded with all of the features you would expect from the world's leading manufacturer of dive computers - and much, much more:

•Universal Graphic Diver Interface™ - Intuitively simple to read and understand

•Air-Integrated™ - Calculates personal air consumption in 3 displays

•Alpha-Numeric Message Box™ - Displays warning messages in preferred language

•Audible Alarm - Alerts you to check Message Box™ and Graphic Diver Interface

•Variable Ascent Rate Indicator™ - Measures ascent rate incrementally

•Dive Log Recall - Recalls 12 most recent dive profiles with time & date stamp

•Backlighted Display - Allows easy viewing at night or in low light situations

•Automatic Altitude Compensation - Fully functional up to 14,000 ft. (4,267 m.)

•Diver Replaceable Batteries

•Ambient Temperature Indication

Before moving on to the next chapter, take the time to familiarize yourself with the universal icons, Fig. 5 on page 8, which make up the Graphic Diver Interface.

MAKING THE DATATRANS PERSONAL

Before you dive with the DataTrans for the first time, you will need to become acquainted with its interactive features, and select your personal display settings using the Control Console and Mode Menu.

If you intend to use your DataTrans as a complete system that includes the high pressure transmitter, the transmitter must first be installed into a high pressure port of your first stage, facing to one side - unless you purchased the DX3™ Integrated First Stage, which includes the transmitter as a built-in component (Fig. 6). Oceanic strongly recommends that this installation be performed by an Authorized Oceanic Dealer at the time of purchase. If this is not possible, refer to the instructions for this procedure on page 80.

NOTE: The DataTrans transmitter is compatible with all Oceanic first stages, but cannot be guaranteed to fit certain models produced by other manufacturers. Check with your Authorized Oceanic Dealer for compatibility with your first stage.

If your DataTrans display module and transmitter were packaged and shipped from the factory as a complete system, the two units have already been “prelinked.” If the two units have been purchased separately by you or your Authorized Oceanic Dealer, it will be necessary to link the display module to the transmitter's frequency code. This can be easily verified upon activation.

A DataTrans that has been packaged and sold as a stand alone computer

PSI

Kg/Cm

display module has been preset at the factory as a non-linked unit, but can easily be linked with a transmitter at any time in the future.

ACTIVATING THE DISPLAY

Before activating the DataTrans display module, it is very important to connect the first stage containing the transmitter to a full cylinder and pressurize by opening the valve. Air pressure of 50 psi (3.5 kg/cm2 ) or more is necessary to activate the transmitter. Position the display module within 3 feet (1 m) of and parallel to the transmitter, and hold it in this location throughout the activation process.

To activate the display of the display module, press the Select button on the right side of the Control Console and release. The DataTrans will immediately enter Diagnostic Mode (Fig. 7), which will display all “8’s,” followed by “dashes,” and then a countdown from 9 to 0. The Message Box will read SELF - TEST until the diagnostic check is completed, at which time the DataTrans will emit a single beep to indicate a successful diagnostic check. If the display module is correctly set to the same frequency code as the transmitter, the Link icon will disappear and cylinder pressure will be displayed numerically. Also, the Air Time Remaining (ATR) bar graph (Fig. 8) will fill indicating 60 minutes.

Throughout this process, the DataTrans checks its display functions, coded frequency link to the transmitter, and battery voltage to ensure that everything is working correctly. If any display or message varies from the information presented here, return the DataTrans to your Oceanic Dealer for inspection. It

Fig. 7 - Diagnostic Mode

BEEEEP!!!

Fig. 8 - Link Verification

(ATR Bar Graph)

will also check the ambient barometric pressure, and calibrate its present depth as zero. At elevations of 3,000 ft. (915 m) or higher, it will recalibrate itself to measure depth in feet (meters) of fresh water.

WARNING - Never activate the DataTrans underwater. This may result in inaccurate depth and no-decompression time displays.

Activation is not possible deeper than 4 ft. (1 m) underwater.

If 2 hours elapse after activation without making a dive, the DataTrans will self-deactivate to save battery power. Check your display module before entering the water to ensure that it doesn’t need reactivation.

PSI

During diagnostic mode, the DataTrans measures the battery voltage level of both the display module and the transmitter to determine whether there is sufficient voltage to complete a full day of diving.

Fig. 9 - Low Battery Warning

WARNING - If either or both of the Low Battery icons remain on display following activation (Fig. 9a), Oceanic strongly recommends that you DO NOT dive until you have obtained battery replacement. See battery replacement procedure on page 77.

If there is not enough battery voltage in the display module to complete a day of diving, the DataTrans will either deactivate itself or not activate at all. If there is not sufficient voltage in the transmitter to complete a full day of diving, the link

PSI

icon and tank pressure of "00" PSI will flash on display (Fig. 10), indicating that the display module is not receiving a signal.

FLASHING LINK ICON

If the display module has been successfully linked to the transmitter upon activation, the Link icon and tank pressure will begin flashing on display whenever the display module is moved out of the range of the transmitter while in Surface Mode. When the display module is returned to its correct proximity to the transmitter, the flashing will stop, and the Link icon will disappear within 5 seconds. Also the Air Time Remaining bar graph will reappear.

If a link was not established during activation, the Link icon will remain flashing on display immediately following Diagnostic Mode, and tank pressure of "00" PSI will be displayed, flashing. This indicates one of the following conditions:

a. The transmitter was not pressurized prior to activation of the display module. b. The display module was not positioned in close proximity to the transmitter during activation or correctly positioned parallel to it. c. The transmitter’s battery voltage has dropped below the level required to transmit a signal. d. The display module is not correctly linked to the same coded frequency as the transmitter.

Fig. 10 - Unsuccessful Link

In the latter case, it will be immediately necessary to follow the prescribed linking procedure outlined on page 24 to set the display module to the coded frequency that matches that of the transmitter, or set a specific link code that will allow the display module to function as a stand alone unit.

SURFACE MODE

Surface Mode immediately follows Diagnostic Mode after initial activation (Fig 11), or after the linking procedure has been performed. It also appears after a dive when you ascend shallower than 3 ft. (1m). Surface Mode is identified by the Surface Time icon (Fig. 11a). Information displayed in Surface Mode is Tank Pressure, Depth, Surface Time with flashing colon, Temperature, Time of Day

PSI

with colon flashing, the Air Time Remaining and Tissue Loading Bar Graphs, if any, and the Air Consumption Indicator. The Date may be viewed as a secondary display by pressing the Select button.

Surface Mode is also the default mode that the DataTrans will automatically return to whenever it has been left unattended while in the Mode Menu for a

period of more than 5 minutes. You may find yourself automatically returned there when you have completed a particular setting. While navigating through the Mode Menu system, you can think of Surface Mode as “home port”.

Fig. 11 - Surface Mode

MODE MENU SYSTEM

In just a moment, you’ll begin navigating through the Mode Menu system to set the various display options that will make the DataTrans your personal computer. If you followed the Linking procedure, you have already developed a

feel for how the Control Console works. The Advance button is used to move through the Mode Menu and change each setting, and the Select button is used to select the mode or setting that is currently on-screen. A brief glossary and hierarchy of the menu system is as follows:

Mode - Each mode provides a different display of information, or access to a submenu or setting. Some modes, such as Dive Mode and Surface Mode, are entered into automatically. Others, such as the Plan Mode and Alternate Dive Mode, are entered into via the Control Console, at the user’s option.

Menu - The main menu allows interactive access from the Surface Mode to Plan, Log, History, Set, and External Access Modes.

Setting - These are display options, such as time, date, language, link and units of measure (imperial or metric) that are determined by you - the user. You can even preprogram your dive by setting the depth and air pressure at which you will be alerted when you are going too deep or running low on air.

Take the time to become familiar with the Menu System by studying the

flowchart diagrams shown on the following pages.

NOTE: If the DataTrans is left unattended for five minutes while in the Mode Menu, it will automatically return to Surface Mode.

AIR & DEPTH ALARM SET POINTS

™

After planning each dive according to the no-decompression bottom times shown to be available in the PDPS, Oceanic strongly recommends that you utilize one of the greatest safety features the DataTrans offers - the Air & Depth Alarm settings.

While the DataTrans uses the Audible Alarm, Message Box, and Graphic Diver Interface to automatically alert you whenever you enter a potentially dangerous situation, such as Decompression Dive Mode, ascending too fast, running low on air, etc., the Alarm settings allow you to preset more conservative limits to better avoid these situations.

Depth Alarm Set Point

™

The Depth Alarm will alert you whenever you reach or exceed the maximum depth Set Point that you have chosen. Of course, if you set the Depth Alarm for a depth that is deeper than the no-decompression or decompression limits for that dive, you will first be alerted by other built-in alarms that you have exceeded those limits before the Depth Alarm is activated. When the Depth Alarm is activated by reaching or exceeding your preset maximum depth, the audible

PSI

BEEEEP!!!

Fig. 15 - Depth Alarm

alarm will sound once per second, while the Message Box flashes the words “TOO DEEP” (Fig. 15, page 21) until you ascend above the depth Set Point. The Depth Alarm may be set for depths ranging from 30-250 feet (9-76 m), in 10 ft (3 & 3.5 m) increments. The setting that you choose for the Depth Alarm does not change the displayed limits of no-decompression dive time remaining.

Air Alarm Set Point

™

The Air Alarm is an acoustic alert that indicates you are approaching a critical Air Time Remaining. The Air Alarm Set Point refers to the surfacing tank pressure reserve of your choice, which may be set for pressures ranging from 300 to 1000 psi.

You will recall that Air Time Remaining is the time that you can remain at your

PSI

present depth and, following a safe ascent, still surface with a prescribed air reserve (identified here as the Air Alarm Set Point).

When your Air Time Remaining reaches 5 minutes, the Air Alarm will emit a double beep as a preliminary warning. If you allow your Air Time Remaining to

BEEEEP!!!

decrease to zero, the tank pressure display will flash and the Message Box flashes the words "AIR ALARM" (Fig. 16) until you ascend to a depth of 5 feet or less.

While an immediate ascent is called for if the Air Time Remaining decreases to zero, there is no reason to panic. The DataTrans has allowed for the air you will consume during a safe ascent, including decompression stops if they are required, and still provide the tank pressure reserve you have chosen, e.g., 300 psi.
