FEATURES OVERVIEW
® INTRODUCTION Welcome to Oceanic and thank you for choosing the DataPlus! Your new DataPlus presents the information that you need before, during, and after your air (or nitrox) dives using Oceanic's intuitive combination of easy to read digital displays and unique identification icons. Tissue loading of nitrogen, accumulation of oxygen, and ascent rate are presented as segmented bar graphs alongside color coded reference indicators that bring quick focus to these important status displays.
DataPlus It is extremely important that you: • Read this owner's guide in sequence and understand it completely before attempting to use the DataPlus. • Check the DataPlus frequently during your dive. • You must also be a trained diver, certified by a recognized training agency in Scuba diving. WARNING: Inspect your DataPlus prior to every dive, checking for any signs of the entrance of moisture, damage to the button membrane, or damage to the LCD display.
® REGULATOR ATTACHMENT If you have purchased the DataPlus in a console version, you will need to have it attached to your regulator first stage by an Authorized Oceanic Dealer. ACTIVATING THE DISPLAY You activate the DataPlus by pressing and releasing the control button located below the display (Fig. 1a).
DataPlus Surface Time display will start counting up from 0:00. If no dive is made within 2 hours (2:00) after activation, the unit will automatically shut off. O2 After displaying the Surface Mode for several seconds, the DataPlus advances to the display FO2 and Air for 5 seconds (Fig. 2) during which time percentage O2 for that dive's nitrox mix can be programmed (set) by pressing and holding the control button.
® PROGRAMMING NITROX MIXES WARNING: FO2 must be set 'before each' nitrox dive. FT DATA PLUS O2 FT MAX GLO Fig. 5 - No Decompression Dive Mode (Air) O2 DATA PLUS GLO Fig. 6 - FO2 = 50% 6 The DataPlus can be used either as an Air computer or a Nitrox computer. To program the percentage O2, press and hold the control button when 'FO2' - 'Air' appears during the Surface Sequence.
DataPlus FO2 must be reset for each repetitive nitrox dive, or the value will automatically be 50 and the dives will be calculated based on 50% O2 for oxygen calculations and 21% O2 (79% nitrogen) for nitrogen calculations. Once a dive is made with the DataPlus set as a nitrox computer (FO2 set for a numerical value), the unit cannot be programmed to operate as an 'Air' computer until 24 hours after the last dive. 'Air' will not be displayed as an option when FO2 appears.
® When underwater, you can quickly focus on the three bar graphs to make sure that 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. a O2 DATA PLUS GLO Fig. 9 - Tissue Loading Bar Graph (TLBG) O2 DATA PLUS The TLBG gives a visual representation of just how close you are to the no decompression limit with a yellow Caution (C.Z.) Zone. This Caution Zone portion of the TLBG (Fig.
DataPlus either per dive allowable O2 or 24 hour period allowable O2. As your exposure, oxygen tolerance dose (OTU), increases during the dive, segments will fill the graph to form an arc along the right perimeter of the LCD. As your OTU level decreases, the bar graph will begin to recede, indicating that additional exposure is allowed for the dive, or 24 hour period.
® completing your ascent. Many divers do this to provide a wider zone of caution from the no decompression limit. b If your depth or elapsed dive time are such that the TLBG enters the red decompression (DECO) zone, the DataPlus will switch to the Decompression Dive FT Mode (Fig. 13) signified with the flashing Decompression Dive Mode icon (Fig. 13a). A decompression stop ceiling will be indicated by the TLBG, and the Stop Ceiling icon (Fig. 13b).
DataPlus AFTER THE DIVE After reaching 3 feet (1 meter) upon ascent, the Surface Mode display (Fig. 15) will replace the Dive Mode display for 10 minutes. After 10 minutes, the DataPlus advances through the sequence of surface displays - Time to Fly, FO2, PO2, PDPS, then back to Surface Mode. Time to Fly shows a 24 hour countdown for your reference. FO2 will show the FO2 set point. PO2 will show the maximum depth allowed for the FO2 set point and your 24 hour O2 dosage.
® tions on nitrogen loading, only the TLBG will be displayed, or if calculations are based upon oxygen loading, only the O2 bar graph will be displayed. a DATA PLUS O2 FT MAX GLO Fig. 16 - Nitrogen Log O2 DATA PLUS Dive Log Mode signified by the Dive Log icon (Fig. 16a) will automatically scroll through the latest 12 dives, starting with the most recent dive first. Two screens are displayed for each dive, one showing data associated with nitrogen and the other showing data associated with oxygen.
DataPlus KNOWING WHEN TO FLY The DataPlus tracks how much surface time has elapsed since you surfaced from your latest dive. The Time to Fly Mode begins a 24 hour countdown that starts 10 seconds after a dive (Fig. 18). During the first 12 hours, the countdown appears for several seconds after the Surface Mode during the Surface Sequence. WARNING: Battery removal and replacement will clear the Time to Fly countdown. DATA PLUS GLO Fig.
® ALTITUDE DIVING The mathematical model within the DataPlus 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 DataPlus will adjust automatically, providing corrected depth and reduced No Decompression times.
DataPlus SHARING THE DATAPLUS WARNING: Never participate in sharing or swapping of a dive computer. Doing so may result in injury or death. The DataPlus 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.

DETAILED OPERATIONS
® a b FT O2 FT MAX DATA PLUS INFORMATIONAL DISPLAYS Each DataPlus 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 DataPlus' displays to avoid any possible misunderstanding that could result in error. This section describes each display in detail. NOTE: Displays associated with oxygen and the O2 bar graph will only appear if FO2 has been set at a value other than 'Air'.
DataPlus a FT O2 indicates the Maximum Depth reached during that dive. In the event that you descend deeper than 330 feet (99.5 meters), this display will only show three dashes (Fig. 21b, page 18) for the remainder of that dive, and as the Max Depth in the Dive Log for that dive. Other displays that utilize these segments of the LCD include - level of PO2 (if greater than 1.40 BAR), and required decompression ceiling stop depth. During a Decompression Dive the required Ceiling Stop Depth (Fig.
® segments of the LCD include - FO2 set point value, 'EA' (External Access), and 'FLY' (during the first 12 hours). A second time display, located in the center right portion of the LCD (Fig. 23b, page 19), indicates Elapsed Dive Time, or Decompression Stop Time required (Fig.24b) for the current stop ceiling indicated, as identified by the Elapsed Dive Time and Ceiling Stop icons, respectively.
DataPlus GRAPHIC DIVER INTERFACE™ NOTE: Displays associated with oxygen and the O2 bar graph will only appear if FO2 has been set at a value other than 'Air'. Three bar graphs referred to as the Graphic Diver Interface™ are located around the perimeter of the DataPlus' LCD (Fig. 25). They are color coded green, yellow, and red to denote normal, caution and danger zones, respectively.
® O2 DATA PLUS GLO Fig. 26 - TLBG Prior to a repetitive nitrox dive, if all segments of the TLBG are displayed during the Pre Dive Planning Sequence™ (PDPS), and no segments of the O2 bar graph are displayed, that next dive is calculated to be controlled by nitrogen loading. O2 DATA PLUS GLO Fig. 27 - O2 Bar Graph 22 The TLBG, located around the left perimeter of the LCD (Fig. 26), monitors 12 different nitrogen compartments simultaneously and displays the one that is in control of your dive.
DataPlus dive, or 24 hour period, segments will add to the graph in an arc beginning from the lower right. As oxygen loading decreases, the bar graph will begin to recede, indicating that additional oxygen accumulation is allowed for that dive and a subsequent dive during that 24 hour period. The O2 bar graph also assists you with managing high partial pressure of O2 by flashing the large red Danger zone segment as a warning when the level of PO2 exceeds the maximum allowed limit of 1.60 BAR (ATA).
® VARIABLE ASCENT RATE INDICATOR™ (VARI) Segments = Speed (rate) 0 = 0 - 20 fpm (0 - 6 mpm) 1 = 21 - 30 fpm (6.5 - 9 mpm) 2 = 31 - 40 fpm (9.5 - 12 mpm) 3 = 41 - 50 fpm (12.5 - 15 mpm) 4 = 51 - 60 fpm (15.5 - 18 mpm) 5 = 61+ fpm (18.5+ mpm) (when 5, all will flash) O2 DATA PLUS The Variable Ascent Rate Indicator™ (VARI), located along the bottom of the LCD screen (Fig.

The different operating modes of the DataPlus are easy to tell apart. Each is clearly identified with unique graphic mode icons (Fig.
® ACTIVATION AND DIAGNOSTIC MODE WARNING: Never activate the DataPlus underwater. This may result in inaccurate depth and no decompression time displays. Activation is not possible deeper than 4 feet (1.5 meters) underwater, or at elevations higher than 14,000 feet (4,267 meters). For Activation, refer to the explanation given on page 4. Diagnostic Mode is displayed immediately following activation.
DataPlus If a dive is not made within 2 hours after activation, the DataPlus will shut off automatically to save battery power. Always check your DataPlus before entering the water to ensure that it has been activated. Surface Mode (Fig. 32), identified by the Surface Mode icon to the right of the Surface Time display, immediately follows Diagnostic Mode after initial activation.
® was a nitrox dive). If you descend during that first 10 minute transition period, time underwater will be considered a continuation of that dive. The time at the surface (if less than 10 minutes) will not be added as elapsed dive time. During the 10 minute transition period, the Log Mode is accessible and will display that dive's data, however, data will not be stored in the unit's memory until the 10 minute period is completed. The PDPS will not appear until after the first 10 minutes.
DataPlus PRE DIVE PLANNING SEQUENCE™ (PDPS) Prior to every dive, Oceanic strongly recommends that you view the PDPS to review the no decompression limits that will help you plan your dive as required to avoid decompression or oxygen toxicity. This is especially important for repetitive dives, when the PDPS (Fig.
® With each depth display you will see either 'predicted' no decompression limits based upon your previous dive profiles (if calculated to be nitrogen controlled), or 'predicted' oxygen tolerance limits based upon either a single dive OTU or your 24 hour accumulation of oxygen (if calculated to be oxygen controlled).
DataPlus NO DECOMPRESSION DIVE MODE Upon descending deeper than 5 feet (1.5 meters), the DataPlus will enter the No Decompression Dive Mode (Fig. 37), identified by the No Decompression Dive icon (Fig. 37b) located to the right of the Main Time display. Information provided includes Current Depth, Maximum Depth for that dive (and Max Depth icon), Elapsed Dive Time (and Elapsed Dive Time icon), and No Decompression Dive Time Remaining for that depth.
® decompression limit, the TLBG will diminish as control shifts to slower compartments. This is a feature of the decompression model that is the basis for multilevel diving, one of the most important advantages the DataPlus offers. (See page 80 in the Reference section for more information pertaining to tissue tracking.) The no decompression algorithm is based upon Haldane’s theory using maximum allowable nitrogen levels developed by Merrill Spencer.
DataPlus DECOMPRESSION DIVE MODE b The DataPlus will help you to avoid and manage decompression. FT Decompression Dive Mode, identified by the Decompression Dive icon (Fig. 39a) located to the right of the Main Time Display, activates when the theoretical no decompression dive limits are exceeded causing the TLBG to pass the yellow caution (C.Z.) zone and enter the red decompression (DECO) zone (Fig. 39b). FT GLO Fig.
® HIGH PO2 DIVE MODE The DataPlus enters the High PO2 Dive Mode (Fig. 41) when partial pressure of oxygen becomes equal to or greater than 1.40 BAR as indicated by the digital display. In the event that this does occur, the value of PO2 (Fig. 41a), and the symbol 'PO2' (Fig. 41b), will be displayed in place of Max Depth and Elapsed Dive Time (if in the No Deco Dive Mode), or the required Stop Depth and Time (if in the Deco Dive Mode).
DataPlus GAUGE MODE Gauge Mode is more fully described on page 55 in the Handling the Extremes section. FT FT MAX O2 If the DataPlus totally exceeds its capacity to predict an ascent procedure, it enters a Permanent Violation Mode and will operate in Gauge Mode for the remainder of that dive and on subsequent dives, only displaying depth and time (Fig. 42). The DataPlus removes calculated displays that no longer provide correct information because of the violation.
® 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. FT DATA PLUS O2 FT MAX GLO Fig. 44 - VARI (Too Fast) a DIVE LOG MODE DATA PLUS O2 FT MAX GLO Fig. 45 - Dive Log Mode 36 The Ascent Rate Indicator shows how fast you are ascending.
DataPlus 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. Each dive has two log screens, one that displays Nitrogen related data and one that displays Oxygen related data. If FO2 was set for 'Air' for that dive, the O2 screen will only display 'FO2' and 'Air'.
® • • • • • O2 DATA PLUS • Today you conducted 2 dives. • Your log sequence would be #2, #1, #3, #2, #1. • This relates to #2 (today' most recent dive), #1 (today's first dive), #3 (Last Saturday's last dive), #2 (Last Saturday's second dive), #1 (Last Saturday's first dive), etc.
DataPlus ended to assist you with deciding when enough surface time has elapsed to fly. It appears once per minute for several seconds during the Surface Sequence showing the word FLY below a countdown display (Fig. 48) that starts at 23:50 (hr : min) and counts down to 12:00 (hr:min). O2 Twelve hours after the last dive, the Surface Sequence (Surface Mode / FO2 / PO2 / PDPS) will be replaced with the Fly Mode (Fig. 49).
® EXTERNAL ACCESS (EA) MODE Using special infrared linking hardware and a unique PC software program, data from your dives can be downloaded (copied) from your DataPlus into an IBM compatible personal computer program running on a Windows® 3.X or Windows® 95 operating system. Instructions for performing the interface and download are provided with the hardware and software package that is available separately at your Authorized Oceanic Dealer. Ask for OceanLink™ for DataPlus.
DataPlus BACKLIGHT FEATURE In addition to using a high contrast LCD for easy readability in low light conditions, the DataPlus' Oceanglo® backlight feature evenly and easily illuminates the full display (Fig. 51). 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. FT DATA PLUS R3 To activate the Oceanglo® backlight during the Dive mode, simply press and hold the control button.
® OPERATING TEMPERATURE 140°F (60°C) FT RESP 32°F (0°C) O Fig. 53 - Operating Temperature Range 42 VER GLO DI DATA PLUS O2 FT MAX The DataPlus will operate in almost any temperature diving environment in the world (Fig. 53) between 32 and 140 °F (0 and 60 °C). At extremely low temperatures, the LCD may become sluggish, but this will not affect it's accuracy.
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 DataPlus is intended for use by recreational divers not engaged in intentional decompression diving. Decompression features are provided only for emergency situations.
DataPlus easy to see how this one mistake can quickly be compounded by several others. The DataPlus 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.
® 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. If you’re not careful, it is possible to enter decompression rapidly, whether at deep depths or during repetitive dives. Yellow 'C.Z.
DataPlus nient 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 (NO DECO) zone. WARNING: Never exit the water with the TLBG in the red Decompression (DECO) 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.
® decompression dive time/depth limits are exceeded causing the TLBG to pass the yellow caution (C.Z.) zone and enter the red decompression (DECO) zone. Information provided includes current depth, current required decompression ceiling stop depth and time (and Ceiling Stop icon), and total ascent time that includes stop time at all ceilings and vertical ascent time calculated at 60 feet (18 meters) per minute. Once every 15 seconds while in the Decompression Dive Mode, an alternate display (Fig.
DataPlus ascending any further, or you will increase your risk of decompression sickness. 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. Doing so will greatly increase your risk of decompression sickness and place the DataPlus into a Conditional Violation Mode described later. When coping with surge and swell, it may be difficult to stay at an exact depth.
® VIOLATION MODES WARNING: If you exceed certain limits, the DataPlus will not be able to tell you how to get safely back to the surface. These situations will make the DataPlus enter 'violation modes' and must be avoided at all costs. They exceed tested limits and can result in loss of some DataPlus functions for 24 hours after the dive in which a violation occurred. a b The Violation Modes that the DataPlus can enter, depending on the situation, are termed “Conditional”, “Delayed”, and “Immediate”.
DataPlus The DataPlus will alert you to the Conditional Violation by flashing the Total 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 DataPlus will continue to function as if no violation had occurred. In this case, 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.
® would then need to follow the ceiling stop depths and time toward the surface until the TLBG recedes toward the caution (C.Z.) zone. Upon reaching zero Total Ascent Time remaining, you should continue decompressing until the TLBG segments are well inside of the green no decompression (NO DECO) zone. 2. Your necessary decompression requires a ceiling depth between 60 and 70 feet (18 and 21 meters).
DataPlus protection, Oceanic strongly recommends that you wait until the TLBG segments are well within the 'green' no decompression (NO DECO) zone, unless a low air condition requires you to surface. 3. You descend deeper than 330 feet (99.5 meters). Oceanic reminds you that the DataPlus is intended for no decompression diving at depths within 130 feet (39 meters). Expanded capabilities of the DataPlus are provided as safety features to assist you with emergency situations.
® IMMEDIATE VIOLATION MODE WARNING: The DataPlus 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 DataPlus design. If you are following these dive profiles, Oceanic advises you not to use a DataPlus dive computer. Immediate Violation Mode occurs when a Decompression Stop depth much greater than 60 feet (18 meters) is required.
DataPlus GAUGE MODE Underwater the Gauge Mode is a continuation of the Immediate Violation Mode that turns the DataPlus into a digital instrument without any decompression or oxygen monitoring functions (Fig. 64). FT MAX DATA PLUS O2 After surfacing, Gauge Mode does not provide the Time to Fly, FO2, PO2, and PDPS features. During the first 12 hour period, the full TLBG and O2 bar graphs will flash and the dive number, and Surface mode icon will be displayed with a Surface Time of '0:00' (Fig. 65).
® EXCEEDING MAXIMUM OPERATING DEPTH Although the DataPlus will withstand the pressures found at 330 feet (99.5 meters), the depth that you can still use all of its features could be much shallower. WARNING: The maximum recommended sport diving depth limit is 130 feet (39 meters). Any deeper dive should be avoided. Special training, equipment and support are necessary for this type of diving. Oceanic does not advocate diving to depths below 130 feet (39 meters), the basis for which is purely theoretical.
dives, the DataPlus will allow a maximum of 7 minutes no decompression dive time available at 160 feet (48 meters). Since part of the 7 minutes is used during descent, the actual time available upon reaching 160 feet (48 meters) can be a very short amount of time. DataPlus It is much more practical to stay within the 11 minutes of no decompression time allowed at 130 feet (39 meters). If you exceed 130 feet (39 meters), watch the DataPlus closely because you can enter decompression rapidly.
® 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 oxygen exposure, as agreed on by all internationally recognized nitrox training agencies. Nitrox diving should therefore be strictly controlled. The DataPlus is designed to help you by providing information of how close you are to oxygen exposure limits.
DataPlus Oceanic strongly recommends that you avoid exceeding oxygen exposure limits, and reminds you that nitrox diving requires special training and understanding of the effects of oxygen toxicity. WARNING: In the event that you exceed the maximum per dive allowable O2 exposure (dose), it is recommended that you allow a surface interval of at least 2 hours before reentering the water.
® mulation (dose) decreases during your surface interval, the bar graph will gradually receed into the yellow caution (C.Z.) zone and green (normal) zone. Oceanic suggests always keeping the O2 Bar Graph in the green (safe) zone. WARNING: DO NOT allow the O2 Bar Graph to enter the red (Danger) zone. Doing so greatly increases the risk of CNS oxygen toxicity, and may result in serious injury or death. Body metabolism varies from person to person, and even from day to day.
DataPlus in increments of '.01' BAR. When PO2 reaches 1.60 BAR, the large red bar graph segment, the PO2 value, and PO2 symbol will flash continuously as a warning (Fig. 70) until the level of PO2 decreases below 1.60 BAR. In the event that you enter High PO2 Dive Mode, you must immediately focus on reducing the partial pressure of O2 by slowly ascending to a shallower depth at a safe rate in accordance with your nitrox training.
® your safety would be jeopardized by losing the use of your DataPlus, an analog or digital backup system or use of standard air (or nitrox) tables is highly recommended. A FINAL WORD CAUTION Although the DataPlus represents the latest in user friendly dive computer technology, it cannot force you to understand how to use it. Before diving with the DataPlus, be sure you thoroughly understand its functions and displays. Contact your local Authorized Oceanic Dealer if you have a question.
CARE & MAINTENANCE
® CARE AND CLEANING The DataPlus 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. Lens Protector (actually transparent) DATA PLUS 64 GLO O2 Prevent Scratches with an Oceanic Lens Protector The console, wrist mount, or hose mount rubber boot that the module is carried in will help protect it from damage.
DataPlus in a 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. Better yet, if you have a console version, attach an Oceanic DataLink™ 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 DataPlus 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).
DataPlus WARNING: Never pressure test the DataPlus 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 DataPlus depth sensor if it is not pressure tested properly. The DataPlus must be placed completely underwater when being pressure tested to protect the depth sensor.
® • Package the module carefully using a cushioning material. • Include a legible note giving specific reason for return, your name, address, daytime phone number, module serial number, and copy of original sales receipt. • Send prepaid and insured to the nearest Oceanic facility. • If you have any questions regarding DataPlus service, call Oceanic’s Parts & Service Department at (510) 562-0500. • Allow two to four weeks for service, plus travel time to and from Oceanic, when estimating your down time.
DataPlus LOW BATTERY CONDITION Oceanic strongly advises that you replace all of the batteries and DO NOT attempt to dive with the DataPlus when the Battery icon remains on display, and that you replace the batteries with new prior to any multi day dive trip that will include a profile of repetitive dives, such as multiple days on a live aboard vessel. O2 You will be alerted to a Low Battery condition by a flashing Battery icon located above the Max Depth display (Fig. 73).
® back far enough to scoop the module out with your index finger. Otherwise, it may be necessary to insert a blunt screwdriver until the tip rests just underneath the module. DO NOT pry the module from the console! Slowly increase the pressure under the module by releasing the tension on the rubber boot. The module will slide up the screwdriver and exit the console. HAN a D HTEN TIG USE COIN ONLY 0PEN Fig. 74 - Battery Hatch 70 WARNING: The following procedure must be closely adhered to.
DataPlus • Turn the unit over to drop out the two 3 volt lithium batteries. Discard, regardless of age or amount of use. • Closely check the metal contacts inside the battery compartment for any signs of stress (bending or breakage), and for any signs of corrosion indicating entrance of moisture into the unit. If found, return your DataPlus to an Authorized Oceanic Dealer, and DO NOT attempt to use the unit until it has received factory service.
® will impair correct contact. • Lightly lubricate the battery hatch o-ring with silicon grease and install it onto the battery hatch. DO NOT roll the o-ring over the threads of the battery hatch. Instead, stretch it slightly to work it down over the slotted end of the battery hatch and into the groove at the base of the threads. NOTE: This o-ring must be a genuine Oceanic Part that can be purchased from your Authorized Oceanic Dealer. Use of any other o-ring will void the warranty.
DataPlus • Check the battery hatch o-ring for damage (nicks, cuts, divots, etc.). If found, discard and replace with new. • Before replacing the o-ring and batteries, flush the battery hatch and compartment with a solution of 50% white vinegar and 50% water. Rinse with fresh water, and dab with tissue paper until completely dry. • Install the o-ring and batteries as previously described.
® • Correct the alignment of the module as needed so that it is straight. • Press the module completely into place with your thumbs, watching the alignment, until it snaps into place. SUMMARY Care and maintenance is simple and easy, and with a small investment of your time you will help keep your DataPlus in top condition for many years of diving enjoyment.
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).
DataPlus 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”.
® Atmospheric pressure decreases as altitude increases above sea level. Weather systems and ambient temperature also affect barometric pressures. Consequently, depth reading instruments that do not compensate for the decrease in pressure indicate depth readings shallower than the depth they are actually at. The DataPlus automatically compensates for decreased ambient pressure when activated at high altitudes up to 14,000 feet (4,267 meters).
DataPlus MORE ABOUT NITROX DIVING WARNING: Diving with enriched nitrogen-oxygen (nitrox) mixtures requires special knowledge of the variations imposed upon divers, their activities, and their equipment by the increase in percentage of oxygen. Oceanic recommends completion of a specialized Nitrox training course by a recognized training agency prior to diving with any enriched nitrogen-oxygen (nitrox) mixtures.
® recognized training agency to teach diving with nitrox. The DataPlus is not intended for use by military or commercial divers. WARNING: In the event that you exceed the maximum per dive allowable O2 exposure (dose), it is recommended that you allow a surface interval of at least 2 hours before reentering the water. If you exceed the maximum 24 hour period allowable O2 exposure (dose), you should allow a surface interval of at least 24 hours before reentering the water.

Learn how to use it and use it wisely. Have fun with the DataPlus, and thank you for being a responsible diver! DI RESP WARNING: Using the DataPlus, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression sickness, i.e. “the bends.
® 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 DataPlus, keep these 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 The following are diving terms that you should become familiar with. Some apply specifically to the DataPlus. Air Dive - A dive conducted using air (approximately 21% oxygen & 79% nitrogen) as the breathing gas. Algorithm - A step-by-step mathematical formula designed to accomplish a particular result (i.e. Dive Time Remaining in the DataPlus).
DataPlus GLOSSARY (cont'd) Decompression Ceiling - The shallowest depth a diver may reach upon ascent without risking decompression sickness (also see TLBG). Decompression Stop - The depth(s) at which a diver must pause during ascent to allow absorbed nitrogen to escape naturally from the tissues. Depth Sensor - An electromechanical device that converts water pressure into an electrical signal, that is converted to a visual depth display.
® GLOSSARY (cont'd) Multiplexing Display - A display on an instrument that alternates to show different information. Multilevel Dive - A type of dive profile where the diver spends various times at different depths (opposite of a Square Wave dive profile). Nitrox - A nitrogen-oxygen breathing gas mixture that contains a higher fraction of oxygen than air. Nitrox Dive - A dive conducted using nitrox (22 to 50 % O2) as the breathing gas.
DataPlus GLOSSARY (cont'd) Safety Stop - A depth at which a diver may choose, but is not required, to pause during ascent to allow absorbed nitrogen to escape naturally from the tissues. Square Wave Dive - A type of dive profile where the entire dive is spent at one depth between descent and ascent. Surface Sequence - An Oceanic term for the sequence of information displayed during surface operation.
