We feel that your new DataTrans will surpass your highest expectations as you become familiar with its broad assortment of features and unique, interactive capabilities that give it the distinction of being a personal diving computer.
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.
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).

Fig. 4 - Bar Graph Displays 6 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.
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.

GETTING STARTED 9
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.
A DataTrans that has been packaged and sold as a stand alone computer 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.
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. a. PSI FT ® Fig. 9 - Low Battery Warning 12 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.
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.
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. PSI FT ® a. 14 Fig. 11 - Surface Mode SURFACE MODE Surface Mode immediately follows Diagnostic Mode after initial activation (Fig 11), or after the linking procedure has been performed.

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.

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. PSI FT ! P!! E EE BE ® Fig.
Turning Off the Audible Alarm The audible portion of the alarm may not be desired by some divers in certain situations. Underwater photographers, for instance, may find that the alarm frightens off marine life at a close distance, and will therefore want to turn it off temporarily before they begin a dive involving that activity. In other situations, such as a multiday trip, when spare batteries are in scarce supply, the audible alarm may be turned off to conserve battery power.
PSI ® Fig. 18 - Air Alarm Setting 24 (MODE:SET will appear, with SET flashing). If you accidentally pass the Set Mode, you will need to press the Advance button repeatedly until MODE:SET appears. Press the Select button to select the Set Mode. 3. After selecting Set Mode, press the Advance button 3 times to advance to the Alarm setting (SET:ALRM will appear, with ALRM flashing). 4.

POSITIONING OF THE DISPLAY MODULE The DataTrans transmitter emits a radio frequency (R/F) signal that radiates a short distance outward in a semicircular pattern that is parallel to the length dimension of the transmitter (Fig. 24, page 30). The coiled antenna inside the display module is designed to receive this signal when the display module is held in a zone parallel to or at a 45 degree angle to the transmitter.
4 seconds after the vehicle motor is shut off or when the display module is moved out of this area. When using a photo strobe, temporary link interruption may occur shortly after the strobe flashes. The link will be restored in 4 seconds. WARNING: During the period of link interrupt the display module will temporarily loose transmitted pressure related functions and displays. These will be regained 4 seconds after the link is restored.
OPERATIONAL MODES The DataTrans operates in 13 different operational modes, including the Diagnostic, Surface, and Set Modes which have already been explained in detail in the previous chapter, “Getting Started.” This chapter will explain the modes the DataTrans operates in before, during, and after a dive.
WARNING: The PDPS predicts only no-decompression times for subsequent dives. Depending on cylinder size and air consumption, you may have less time available than shown in the PDPS because of air or other limitations. PSI FT ® Fig. 27 – No Decompression Dive Mode 34 PDPS no-decompression times are displayed for depths where there is at least 1 minute available. This takes into account a descent rate of 75 ft./min (23 m/ min).
As your depth and bottom time increase, however, No-Decompression Time eventually becomes the more limiting factor, and the Dive Time Remaining Icon will indicate that the numeric display is showing this value. No-Decompression Dive Mode numerically displays Cylinder Pressure, Current Depth, and No Decompression or Air Dive Time Remaining (whichever is less). The Graphic Diver Interface displays the TLBG, VARI, ATR, and ACI bar graphs.
DECOMPRESSION DIVE MODE The DataTrans will help you to avoid, or easily manage, decompression. Before explaining further, read the following warning. a. PSI WARNING: Oceanic recommends the application of responsible diving practices and does not recommend decompression diving or diving deeper than 130 feet (39 m), as these practices will greatly increase your risk of decompression sickness. FT ® c. b. Fig.
When the audible alarm alerts you of entry into decompression, you must immediately change the focus of your dive to getting safely back to the surface. Upon hearing the alarm and seeing the TLBG enter the 10 FT/ 3M STOP zone, you should immediately begin a safe ascent to a depth slightly deeper than or equal to 10 feet (3m). The amount of decompression credit time you receive is dependent on depth, with slightly less credit given the deeper you are.
VIOLATION MODES The DataTrans enters one of three Violation Modes when you exceed its ability to predict an ascent procedure. These modes are explained fully in the “Handling the Extremes” section beginning on page 55. PSI FT ® Fig. 32 - Gauge Mode 38 GAUGE MODE If the DataTrans enters a Permanent Violation Mode, it will operate only in Gauge Mode on subsequent dives. The DataTrans removes the displays that can no longer provide correct information because of the violation.
complete your ascent with the TLBG inside of the green zone. While you cannot provide a guarantee against the occurrence of decompression sickness, you may choose your own personal zone of caution based upon your individual age, physique, excessive weight, training, experience, etc. to reduce the statistical risk. The Variable Ascent Rate Indicator™ (VARI) will show how fast you are ascending, in relation to the prescribed ascent rate for the depth zone you are in.
DIVE LOG MODE Log Mode can be accessed using the Mode Menu while on the surface. This mode displays 3 separate screens of information for each dive recorded, for up to 12 of your most recent dives. Log Mode will store this information indefinitely, until a subsequent (13th) dive displaces the earliest dive recorded, on a first in, first out basis. To eliminate confusion, each dive is separately “stamped” with the date on which it was made, and the time of day when it was started. ® a.
5. To display the time of day when the dive started, press the Advance button. 6. Press the Advance button once more to view the actual dive information (Fig. 35). Displayed will be: Log Mode Icon, Dive number (35a), Surface Time - between that dive and the one previous to it (35b), water Temperature (35c) at the end of the dive, Bottom Time (35d), and Maximum Depth (35e).
TIME TO FLY MODE The longer you wait to fly after diving, as you should be aware from your own training, the more you will reduce your exposure to decompression sickness. The Time To Fly counter begins counting down ten minutes after the last dive has ended to assist you with deciding when enough surface time has elapsed to fly. It appears prior to the PDPS when you access Plan Mode, and shows the word “FLY” with a countdown that starts at 23 hours and 50 minutes (Fig. 36).

To access the information provided in History Mode, follow this procedure, beginning in Surface Mode: 1. Press the Advance button to enter the Mode Menu. MODE:PLAN will appear, with PLAN flashing, indicating that Plan Mode is the first available option. 2. Press the Advance button 2 more times to advance to the History Mode (MODE:HIST will appear, with HIST flashing).
EXTERNAL ACCESS MODE (EACC) “EACC,” referred to as the External Access Mode, is the last mode selection in the main Mode Menu before Surface Mode (Fig. 38). This special mode enables you to download recorded log and history information from your DataTrans computer to an IBM compatible PC using an OceanLink™ download interface kit that may be purchased separately from your Authorized Oceanic Dealer. Complete instructions for this procedure are included with the kit. ® Fig. 38 - External Access Mode a. b.

Time Display The Time Display, located in the middle of the LCD (Fig. 39c, page 44), indicates Air Time Remaining, No Decompression Dive Time Remaining, Bottom Time, Total Decompression Ceiling Stop Time or Surface Time, depending on the mode that the DataTrans is in. Time displays are in hour:minute format, i.e.; 1:06=one hour and six minutes (not 106 minutes).

Alarm and flashing VARI segments will alert you if your ascent rate exceeds 60 ft./min (18 m/ min). The Variable Ascent Rate Indicator is a unique DataTrans feature that has been granted a U.S. Patent.
DIVE TIME REMAINING One of the most important pieces of information on the DataTrans is the patented Dive Time Remaining numeric display. To numerically display Dive Time Remaining, the DataTrans constantly monitors two critical pieces of information; no decompression status and rate of air consumption.
Air Time Remaining (ATR) bar graph regardless of what is displayed in the numeric Dive Time Remaining display. The ATR bar graph will provide the only source of Air Time information if you are in a decompression or violation mode. The DataTrans calculates Air Time Remaining using a patented algorithm that is based on a diver's individual air consumption rate and depth. Tank pressure is measured once each second, and an average rate of consumption is calculated over a 90 second period.
PSI FT ® a. Fig. 47 - No-Decompression Dive Time Remaining 50 No Decompression Dive Time Remaining No Decompression Time is calculated based on the amount of nitrogen absorbed by twelve hypothetical tissue compartments. The rates each of these compartments absorb and release nitrogen is mathematically modeled and compared against a maximum allowable nitrogen level.
PRIMARY ALARMS 1. Potential Danger – One Double Beep During situations that may pose potential danger, one Double Beep is emitted from the DataTrans. These situations are as follows: • Entry into decompression. • Decreasing to 5 minutes of Air Dive Time Remaining. • Air Time Remaining is within 5 minutes of required Decompression time. 2.
• Required Decompression exceeds a 40 FT/ 12 M ceiling. 2. Transition – Short Beep To indicate that a command has been accepted, the DataTrans will emit a Short Beep whenever you use the control console, and immediately following activation and the Diagnostic Mode.

WARNING: Until it has shut itself off, you must not use the DataTrans at a different altitude than the altitude where it was originally activated. Doing so will result in an error equal to the difference in barometric pressure, and possibly a false dive mode. Reset is possible by battery removal and replacement.
reasonably assured a diver will remain symptom free upon ascent to altitude in a commercial jet airliner (altitude up to 8,000 ft./2440 m). Divers who plan to make daily, multiple dives for several days, or make dives that require decompression stops, should take special precautions and wait for an extended surface interval beyond 12 hours before flight”. Both the UHMS and DAN agree that “There can never be a flying after diving rule that is guaranteed to prevent decompression sickness completely.
HANDLING THE EXTREMES 55
56 VER DI RESP O N SI LE B HANDLING THE EXTREMES There are few legitimate excuses for making unplanned Decompression dives, and the consequences of this type of diving can be severe. By entering decompression, you automatically impose a “ceiling” above you which you cannot immediately ascend beyond, denying you free access to the surface.
Decompression diving should therefore be strictly avoided. The DataTrans is designed to help you by providing a complete representation of how close you are to entering decompression. In the event that you do inadvertently enter decompression, the DataTrans can provide you with limited information to help you ascend to the surface, if you follow the instructions given in this chapter.
The maximum depth at which you can still use all of the DataTrans' features is 250 feet (76 m). WARNING: The maximum recommended sport diving limit is 130 feet (39 m). Any deeper dive should be avoided. Special training and equipment are necessary for this type of diving. Oceanic does not advocate diving to depths below 130 feet (39 m), or decompression diving. PSI FT ! EP ! BE EEP B ® Fig. 51- Decompression warning 58 On a first “clean” dive, the DataTrans will allow 7 minutes at 160 feet (48 m).
The time indicated in the Message Box represents only the Decompression Stop Time required below the current ceiling and at your present depth, whereas the total decompression time required for all decompression stops is presented in the primary numeric display (Fig. 52). EMERGENCY DECOMPRESSION After entering decompression (especially at deeper depths) the TLBG may fill the 10 FT/ 3M, 20 FT/ 6M, 30 FT/ 9M and 40 FT/ 12M decompression stop zones rapidly.
VIOLATION MODES Warning: If you exceed certain limits, the DataTrans will not be able to tell you how to get safely back to the surface. These situations will make the DataTrans enter "violation modes" and must be avoided at all costs. They push decompression theory to the limits and can result in loss of some DataTrans functions for 24 hours after the last dive of a day in which a violation occurred. There are three different Violation Modes that the DataTrans can enter depending on the situation.
Ascent to Shallower than the Required Decompression Ceiling The DataTrans will enter the Conditional Violation Mode if you ascend shallower than the decompression ceiling indicated by the TLBG (Fig. 53). A momentary rise above the ceiling, such as with a surge or swell, will cause this to happen. Therefore you should stay slightly deeper than the exact ceiling depth, watching the DataTrans closely when managing decompression.
DELAYED VIOLATION MODE When the DataTrans enters the Delayed Violation Mode, it retains the capacity to tell you how to get back to the surface. A Delayed Violation Mode will be encountered in the following situations: Spending More than Five Minutes Above Required Decompression Ceiling As previously described, if you stay above the decompression ceiling for more than five minutes, you will enter the Delayed Violation Mode.
alternately flashes “EXCEEDED” and “CEILING” (Fig. 54) four times. In this situation, the amount of decompression time needed to get back to the surface will still be displayed numerically in the Decompression Time display. To get back to the surface, you must safely ascend to just deeper than 40 feet (12 m) staying as close to 40 feet (12 m) as possible without causing the Message Box to flash.
IMMEDIATE VIOLATION MODE Warning: The DataTrans enters Immediate Violation Mode when a situation totally exceeds its capacity to predict an ascent procedure. These dives represent gross excursions into decompression that are beyond the boundaries and spirit of the DataTrans design. If you are following these dive profiles, Oceanic advises you not use a DataTrans dive computer. Immediate Violation Mode occurs when - a Decompression Stop depth greater than 50 feet (15 m)is required. PSI FT E BE ® Fig.
a. PERMANENT VIOLATION MODES Entering the Immediate Violation Mode, then Gauge Mode, will result in loss of some DataTrans functions for twenty four hours after that dive. This condition which involves loss of some decompression monitoring functions is considered Permanent Violation. GAUGE MODE The DataTrans will operate with limited functions in Gauge Mode during the twenty four hours after a dive in which a Permanent Violation occurred.
AIR TIME REMAINING DURING DECOMPRESSION Oceanic strongly recommends that you avoid entering decompression. The DataTrans cannot provide you with a backup air supply for emergencies or the ascent line you will need, and decompression diving greatly increases your risk of decompression sickness. If you inadvertently exceed no decompression limits, the DataTrans will provide critical information regarding your remaining air supply.
CAUTION ZONE (C.Z.) When you learned how to dive, you were taught not to get too close to the No Decompression limits. The Tissue Loading Bar Graph Caution Zone (C.Z.) offers you a way to consistently monitor how close you are coming to the No Decompression limit. Oceanic suggests always leaving the water with the TLBG in the green No Decompression zone. WARNING: Never exit the water with the TLBG in the red decompression zone.
140° F PSI FT ® 32° F Fig. 59 – Operating temperature range 68 WHAT TO DO IF YOUR DATATRANS QUITS WORKING While No Decompression diving, if you find that any major piece of equipment is not working, you must abort the dive immediately and surface slowly in a controlled manner. If your DataTrans quits for any reason, it is important that you have anticipated this possibility and are prepared for it.
not affect the DataTrans' accuracy. If stored or transported in areas below freezing, you should warm with body heat before diving. Even though the DataTrans will operate in a wide range of temperatures, it is possible to damage the electronics if left exposed to direct sunlight, or in a hot confined space like a car trunk. After a dive, cover the DataTrans and keep it out of the sun. If inadvertently left in the direct sunlight the LCD may become totally black.
predictions of decompression status. This rule applies to the use of all dive computers, but is especially important when using the DataTrans, due to the very personal information it provides. A FINAL WORD OF CAUTION Although the DataTrans represents the latest in user friendly dive computer technology, it cannot force you to understand how to use it. Before diving with the DataTrans, be sure you thoroughly understand its functions and displays.
CARE and MAINTENANCE 71
PSI ® FT CARE AND MAINTENANCE The DataTrans is a sensitive electronic instrument. Although it has been designed to withstand the rigors of diving, it still must be handled carefully to protect from shock, excessive heat, chemical attack, and tampering. The DataTrans' housing is made of an impact resistant resin that is extremely shock resistant but is susceptible to chemical attack and scratches.
following each dive as you normally would, according to the proper maintenance procedures prescribed for that model. If possible, use lukewarm water to dissolve any salt crystals. Salt deposits can also be dissolved using a slightly acidic vinegar/water bath. After removal from a fresh water bath, place the DataTrans under gently running water and towel dry before storing. Transport your DataTrans cool, dry, and protected.
OCEANIC CORPORATE H.Q. San Leandro, California WARNING: If you are in doubt about the accuracy of your DataTrans' depth readings, DO NOT attempt to dive with it until it has been inspected by Oceanic Customer Service (Fig. 60).

DECOMPRESSION VIOLATION LIMITS As described earlier, the DataTrans has two permanent violation modes, Delayed and Immediate. If either mode is entered underwater, your DataTrans will loose some functions. Figure 68, page 85 provides a graph indicating where permanent violation modes occur on an extreme first dive profile between 160 and 190 feet (49 and 58 m). The graph is only an example and not a suggestion for planning a dive. It is possible to exceed the limits shown in Fig.

RESPONSIBLE COMPUTER DIVING Since the advent of dive computers, it is a common mistake to assume that the old traditional rules of diving no longer apply, but the truth is just the opposite. Before you dive using your DataTrans, keep these basic rules in mind: • Plan each dive, and dive your plan - Your computer was not designed to make decisions for you, only to provide you with the information you need to make responsible decisions for yourself.

GLOSSARY Diving terms to become familiar with. Many apply specifically to the DataTrans. ACI - Abbreviation for Air Consumption Indicator. Air Consumption Indicator - A graphic display of air consumption rate. Air Integrated Dive Computer - A dive computer that monitors and displays cylinder pressure in addition to no decompression information. Algorithm - A step-by-step mathematical formula designed to accomplish a particular result (i.e. Dive Time Remaining in the DataTrans).
GLOSSARY (continued) proximity to decompression. Ceiling - See decompression ceiling. Clean Dive - A dive preceded by 24 hours of no diving activity. Competitive Dive - A dive conducted for profit or prize. Compartment - A term applied to the hypothetical modeling of nitrogen absorption in the tissues (more accurate than the term “tissue” because dive computer models have no direct relation to human tissues). DCS - Abbreviation for decompression sickness, i.e., “the bends”.
GLOSSARY (continued) tank pressure. Graphic Diver Interface™ - A feature of Oceanic dive computers. Easily understandable color coded bar graphs that indicate diver status; green = normal, yellow = caution, red = danger. Icon - a small pictorial representation of an operational mode LCD - Abbreviation for liquid crystal display, an easily viewed low voltage display usually found on dive computers Maximum Depth - The deepest depth attained during a dive.
GLOSSARY (continued) Pre Dive Planning Sequence™ - A display of available dive times at 10 ft. (3m) intervals from 30 to 160 ft. (9 to 48 m) used when dive planning. Pressure Sensor - an electro-mechanical device that converts cylinder pressure into an electrical signal that the DataTrans converts into cylinder pressure and air time remaining displays. Repetitive Dive - Any dive that takes place within 12 hours of a previous dive.
