THE DATA100 IS EASY TO USE
¨ INTRODUCTION Welcome to Oceanic and thank you for choosing the Data100! Your new Data100 presents the information that you need before, during, and after your dives using Oceanic's intuitive combination of easy to read digital displays and unique identification icons. Tissue loading of nitrogen and ascent rate are presented as segmented bar graphs alongside color coded reference indicators that bring quick focus to these two important status displays.
Data100 It is extremely important that you: • Read this owner's guide in sequence and understand it completely before attempting to use the Data100. • Check the Data100 frequently during your dive. • You must also be a trained diver, certified 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.
¨ REGULATOR ATTACHMENT b If you have purchased the Data100 in a console version, you will need to have it attached to your regulator first stage by an Authorized Oceanic Dealer. ACTIVATING THE DISPLAY a DATA 100 GLO Fig. 1 - Surface Mode a FT DATA 100 GLO Fig. 2 - Pre Dive Planning Sequence 4 You activate the Data100 by pressing and releasing the control button located below the display (Fig. 1a). Depressing the button during the Dive Mode will activate the display's Oceanglo™ backlight.
WARNING: The Data100 must be manually activated and be in the Surface Mode or PDPS Mode prior to start of a dive. The unit will not activate automatically by immersion in water. Data100 a FT MAKING A DIVE Once you enter the water and descend to a depth below 5 feet (1.5 m)., the Data100 changes to the No Decompression Dive Mode (Fig. 3) signified by the No Decompression icon (Fig. 3a).
¨ DATA 100 The Tissue Loading Bar Graph® (Fig 5) represents nitrogen loading, showing your relative no decompression or decompression status. As your depth and bottom time increase, segments will fill the graph to form an arc around the perimeter of the LCD. As you ascend to shallower depths, this bar graph will begin to recede, indicating that additional no decompression time is allowed for multilevel diving.
feet (5-6 meters) is strongly recommended as a standard procedure before completing your ascent. Many divers do this to provide a wider zone of caution from the no decompression limit. Data100 a FT If your depth or bottom time is such that the TLBG enters the red zone, the Data100 will switch to the Decompression Dive Mode (Fig. 7) signified with the flashing Decompression Dive Mode icon (Fig. 7a). A decompression stop ceiling will be indicated by the TLBG, and the Stop Ceiling icon (Fig. 7b).
¨ AFTER THE DIVE DATA 100 GLO Fig. 9 - Surface Mode a DATA 100 GLO Fig. 10 - Dive Log Mode 8 After reaching 3 feet (1 meter) upon ascent, the Surface Mode display (Fig. 9) will replace the Dive Mode display. After 10 minutes in the Surface Mode, and at once each minute afterward, the Surface Mode display will alternate with the Pre Dive Planning Sequence (PDPS). The PDPS will show 'adjusted' no decompression limits based on the nitrogen calculated to have been absorbed during your last dive.
Data100 KNOWING WHEN TO FLY Due to the present lack of a complete data set derived from actual human testing, there are different recommendations cited by various scientific organizations for the amount of time a diver should wait before flying after diving.
¨ ALTITUDE DIVING The mathematical model within the Data100 accounts for the reduced No Decompression time available at higher elevations based on NOAA (National Oceanic and Atmospheric Administration) guidelines. When diving in high altitude lakes or rivers from 2,000 to 14,000 feet (610 to 4,268 meters), the Data100 will adjust automatically, providing corrected depth and reduced No Decompression times.

¨ a FT b DATA 100 GLO (No Decompression Mode) FT c DATA 100 GLO (Decompression Mode) Fig. 13 - Depth Displays 14 INFORMATIONAL DISPLAYS Each Data100 numeric or graphic display represents a unique piece of information. It is imperative that you understand the formats, ranges, and values of the information represented by the Data100's displays to avoid any possible misunderstanding that could result in error. This section describes each display in detail.
DATA100 seconds when the screen toggles to the Alternate display once every 15 seconds while in the Decompression Mode. Time Display The Main Time display, located in the center of the LCD (Fig. 14a), indicates elapsed Surface Time, theoretical Dive Time Available during the PDPS, No Decompression Dive Time Remaining, or Total Ascent Time required depending on the mode that the Data100 is in at the time. A second time display, located in the lower right portion of the LCD (Fig.
¨ GRAPHIC DIVER INTERFACE™ Two bar graphs referred to as the Graphic Diver Interface™ are located around the perimeter of the Data100's LCD. They are color coded green, yellow, and red to denote normal, caution and danger zones, respectively. The Graphic Diver Interface allows you to make quick status checks underwater of your no decompression status and ascent rate.
DATA100 further divided into 6 Decompression 'ceiling' zones representing 10FT/ 3M, 20FT/ 6M, 30FT/ 9M, 40FT/ 12M, 50FT/ 15M, and 60FT/ 18M stop depths.

¨ OPERATIONAL MODES The Data100’s different operating modes are easy to tell apart. Each is clearly identified with graphic mode icons (Fig. 17) which provide quick visual reference during the various modes of operation. Become familiar with all modes so that you understand exactly what information the Data100 is providing you at any specific time.
DATA100 Diagnostic Mode is displayed immediately following activation. After pressing and releasing the control button, the Diagnostic Mode will display all "8's” followed by dashes, and then a countdown from 9 to 0 (Fig. 18). During the countdown, the Data100 checks its display functions and battery voltage to ensure everything is working properly, then changes to the Surface Mode. If battery voltage is below the level sufficient for a day's operation, the Battery icon will be displayed, flashing.
¨ Surface Mode Surface Mode, identified by the Surface Mode icon to the left of the Surface Time display, immediately follows Diagnostic Mode after initial activation. Information provided includes, the number of the most recent dive made ('0' if no dive has been made since activation), elapsed Surface Time with the colon flashing, and tissue (nitrogen) loading, if any, as the TLBG.
DATA100 completed. The PDPS will not appear until after the first 10 minutes. Once 10 minutes have elapsed, the Surface Mode icon stops flashing. Other information will continue to be displayed as described above. Time to Fly will appear once per minute at the beginning of the PDPS. That dive will then be entered into the memory of the Log Mode, and a subsequent descent will be considered a new dive.

DATA100 Information provided includes Current Depth, Elapsed Dive Time (and Elapsed Dive Time icon), No Decompression Dive Time Remaining for that depth, and Maximum Depth for that dive (and Max Depth icon). The Graphic Diver Interface is also active, displaying nitrogen loading (TLBG) and ascent rate (VARI). No Decompression Dive Time Remaining is the maximum amount of time you can stay at your current depth before entering a decompression situation.
¨ The no decompression algorithm is based upon Haldane’s theory using maximum allowable nitrogen levels developed by Merrill Spencer. Repetitive diving control is based upon experiments designed and conducted by Dr. Ray Rogers and Dr. Michael Powell in 1987. Diving Science and Technology® (DSAT), a corporate affiliate of PADI®, commissioned these experiments and now uses the findings in the Recreational Dive Planner™ distributed by PADI.
DATA100 Decompression Dive Mode, identified by the Decompression Dive icon located to the left of the Main Time Display (Fig. 24a), activates when the theoretical no decompression dive time/depth limits are exceeded causing the TLBG to pass the 12 o'clock position and enter the red decompression zone (Fig. 24b). Information provided includes current depth, current required decompression ceiling stop depth and time (and Ceiling Stop icon - Fig.
¨ You must stay at, or slightly below, the ceiling stop depth indicated until the TLBG recedes into the next shallower zone before ascending any further, or you will increase your risk of decompression sickness. a b FT DATA 100 b GLO Fig. 26 - Decompression Stop Depth 26 The amount of decompression credit time you receive is dependent on depth, with slightly less credit given the deeper you are. Still, you must never ascend shallower than your decompression ceiling.
DATA100 Violation Modes The Data100 enters one of three different 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 33. Gauge Mode If the Data100 enters a Permanent Violation Mode, it will operate in Gauge Mode on subsequent dives, only displaying depth and time. The Data100 removes calculated displays that no longer provide correct information because of the violation.
¨ FT DATA 100 GLO Fig. 28 - VARI (Too Fast) a complete all of your ascents with the TLBG inside 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 Ascent Rate Indicator (Fig. 28) shows how fast you are ascending.
DATA100 Dives are displayed in a sequence that starts with the dive most recently recorded scrolling back to the oldest of the 12 stored for viewing. Thus, your most recent dive will always be the first shown in the log sequence, the second most recent will appear next, etc. You can choose to either press and release, or press and hold, the button.
¨ • Elapsed Dive Time (and Elapsed Dive Time icon) • VARI - maximum ascent rate at any time during that dive • TLBG - tissue loading at the time you surfaced from the dive. Time to Fly Mode DATA 100 GLO Fig. 31 - Fly Mode (First 12 Hours) As you should be aware from your own training, the longer you wait to fly after diving, the more you will reduce your exposure to decompression sickness.
DATA100 After a surface interval of 12 hours, you may choose to fly, provided that your dive profile(s) did not enter decompression. If your diving involved decompression or a repetitive, multi day profile, it is strongly recommended that you wait a full 24 hours after your last dive to add a greater degree of protection. See page 50 for More About Flying After Diving, and DAN's guidelines. External Access Mode (EA) This special mode is not used by the diver.
¨ BACKLIGHT FEATURE In addition to using a high contrast LCD for easy readability in low light conditions, the Data100's Oceanglo™ backlight feature evenly and easily illuminates the full display (Fig. 34). This means that on night dives, in caves, or any other low light situation you illuminate the display when you wish to view it, with the touch of a button. To activate the Oceanglo™ backlight during the Dive mode, simply press and hold the control button.
HANDLING THE EXTREMES
¨ EMERGENCY DECOMPRESSION There are few legitimate excuses for making unplanned Decompression dives, and the consequences of this type of diving can be severe. Decompression diving requires special training. The Data100 is intended for use by recreational divers not engaged in intentional decompression diving. Decompression features are provided only for emergency situations.
DATA100 The Data100 is a sophisticated instrument designed with capabilities that go beyond the range of recreational diving with compressed air. It should not be considered, however, that these built-in capabilities provide any implied approval or consent from Oceanic for individuals to exceed the defined limits of recreational dive profiles, as agreed on by all internationally recognized training agencies. Decompression diving should therefore be strictly avoided.
¨ WARNING: Existing data for making planned decompression dives is extremely limited, and virtually nonexistent for repetitive decompression diving. You must therefore avoid decompression diving and allow a surface interval of at least 24 hours before reentering the water in the event a dive requiring decompression is made. Yellow Caution Zone If you’re not careful, it is possible to enter decompression rapidly, whether at deep depths or during repetitive dives.
close you are coming to the No Decompression limit, located at the 12 o'clock position. Oceanic suggests always leaving the water with the TLBG in the green No Decompression zone. DATA100 WARNING: Never exit the water with the TLBG in the red Decompression zone. Doing so greatly increases the risk of decompression sickness, and may result in injury or death. Body metabolism varies from person to person, and even from day to day.
¨ FT DATA 100 GLO Fig. 37 - Out of Range (>330 ft or 99.5 m) Ceiling icons Red zone FT DATA 100 GLO Fig. 38 - Recognizing Decompression Mode 38 The maximum depth that the Data100 will display all of its features, is 330 feet (99.5 meters). Upon exceeding 330 feet (99.5 meters), the TLBG will flash and Depth and Max Depth displays will only indicate and flash three dashes “ ” signifying that you are 'Out of Range' (Fig. 37).
DATA100 VIOLATION MODES WARNING: If you exceed certain limits, the Data100 will not be able to tell you how to get safely back to the surface. These situations will make the Data100 enter 'violation modes' and must be avoided at all costs. They push decompression theory to the limits and can result in loss of some Data100 functions for 24 hours after the dive in which a violation occurred.
¨ Ascent Time display until you descend below the required decompression stop ceiling. If you descend below the required decompression ceiling before 5 minutes have elapsed, the Data100 will continue to function as if no violation had occurred, and you will not be penalized for your breach of the ceiling. For the first 5 minutes in the Conditional Violation Mode, no off-gassing credit will be given, and for each minute above the ceiling, 11/2 minutes of penalty time is added to decompression stop time.
DATA100 ceiling toward the surface as the TLBG recedes toward the Caution zone. Upon reaching zero Total Ascent Time remaining, you should continue decompressing until the TLBG segments are well inside of the green No Decompression zone, to the left of the 12 o'clock position. 2. Your necessary decompression requires a ceiling depth between 60 and 70 feet (18 and 21 meters). The display will be the same as the Decompression Mode with all segments of the TLBG flashing (Fig. 40).
¨ 3. You descend deeper than 330 feet (99.5 meters). FT DATA 100 GLO Fig. 41 - Out of Range FT Oceanic reminds you that the Data100 is intended for no decompression diving at depths within 130 feet (39 meters). Expanded capabilities of the Data100 are provided as safety features to assist you with emergency situations. As previously described on page 38, upon descending deeper than 330 feet (99.
DATA100 Immediate Violation Mode occurs when a Decompression Stop depth much greater than 60 feet (18 meters) is required. This situation would be preceded by entering the Delayed Violation Mode previously described. The Data100 cannot calculate decompression ceilings greater than 60 feet (18 meters) and offers no indication of how much time spent underwater would result in the need for greater than a 60 foot /18 meter decompression ceiling.
¨ Permanent Violation Entering the Immediate Violation Mode, then Gauge Mode, will result in loss of all Data100 decompression monitoring and calculating functions for 24 hours after that dive. This condition is considered a Permanent Violation. UNEXPECTED LOSS OF DISPLAYED INFORMATION While No Decompression diving, if you find that any major piece of equipment is not functioning correctly, you must abort the dive immediately and surface slowly in a controlled manner.
SHARING THE DATA100 DATA100 WARNING: Never participate in sharing or swapping of a dive computer. Doing so may result in injury or death. The Data100 provides information based upon a diver’s personal dive profile, and therefore must not be “shared” between divers. You should never, under any circumstances, swap your computer with another unit between dives, or share your computer with another diver underwater.
¨ Even though the Data100 will operate in this 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 the dive, cover the Data100 and keep it out of the sun. If inadvertently left in the direct sunlight, the LCD display may become totally black. If this occurs, immediately immerse the Data100 in water. The display should recover its normal appearance after a few minutes.
CARE and MAINTENANCE
¨ CARE AND CLEANING The Data100 is a sensitive electronic instrument. Although it has been designed to endure the rigors of diving, it still must be handled carefully to protect it from shock, excessive cold or heat, direct sunlight, chemical attack, neglect and tampering.

rack, tuck the console into a BC pocket, or between the waistband and the bladder of the BC. Keep it off the deck and protected from undue shock. DATA100 Better yet, if you have a console version, attach an Oceanic DataLink™ (Fig. 46) quick disconnect on the high pressure hose that connects your pressure gauge to your regulator first stage. This allows easy removal of the complete instrument console when not in use between dives.
¨ ANNUAL DEALER INSPECTIONS & FACTORY SERVICE As with all Oceanic instrumentation, the Data100 should be inspected annually by an Authorized Oceanic Dealer who will perform a factory prescribed function check and inspection for damage or wear. To keep the two year limited warranty in effect, this annual inspection must be completed one year after purchase (± 30 days).
WARNING: Never pressure test the Data100 in an air environment. Doing so may damage the depth sensor; possibly resulting in erroneous depth or time readings. It is possible to damage the Data100 depth sensor if it is not pressure tested properly. The Data100 must be placed completely underwater when being pressure tested to protect the depth sensor.

REFERENCE
¨ MORE ABOUT FLYING AFTER DIVING In 1990 the Undersea and Hyperbaric Medical Society (UHMS) published a set of guidelines aimed at minimizing the possibility of decompression sickness due to flying too soon after diving. The UHMS suggests* divers using standard air cylinders and exhibiting no symptoms of decompression sickness wait 24 hours after their last dive to fly in aircraft with cabin pressures up to 8,000 feet. (2,440 meters).
DATA100 Both the UHMS and DAN agree that “There can never be a flying after diving rule that is guaranteed to prevent decompression sickness completely. Rather, there can be a guideline that represents the best estimate for a conservative . . . surface interval for the vast majority of divers. There will always be an occasional diver whose physiological makeup or special diving circumstances will result in the bends”.
¨ WARNING: Altitude compensation provided by the Data100 takes place when the unit is activated. DO NOT dive at any different altitude until the Data100 shuts off and will recalibrate when reactivated at the new altitude. MULTIPLE TISSUE TRACKING The Data100 tracks twelve tissue compartments with half times ranging from 5 to 480 minutes. The TLBG always displays the controlling compartment that is the only one important at that time.

¨ NO DECOMPRESSION LIMITS Note how the No Decompression Limits for the Data100 are contrasted with the U.S. Navy limits (Fig. 54, page 65). For most depths, the Data100 provides somewhat less no decompression times than the U.S. Navy Tables. However, while the no decompression limits may be less, you will receive greatly increased allowable bottom times as you take advantage of the multilevel dive capabilities offered by the Data100.

DATA100 DECOMPRESSION VIOLATION LIMITS As described earlier in the Handling the Extremes section, the Data100 has two permanent violation modes, Delayed and Immediate. If either mode is entered while underwater, your Data100 will loose some functions. Figure 56, page 66, provides a graph indicating where permanent violation modes occur on a sample extreme first dive profile between 160 and 190 feet (49 and 58 meters). The graph is only an example and not a suggestion for planning a dive.
¨ WARNING: Oceanic advocates responsible diving practices and does not recommend decompression diving, or diving below 130 feet (39 meters). The decompression capabilities of the Data100 are intended strictly for emergency use. Decompression diving is inherently hazardous and greatly increases your risk of decompression sickness - even when performed according to the computer's calculations.
DATA100 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 Data100, 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.
