DEFINITION OF WARNINGS, CAUTIONS AND NOTES Throughout this manual, special references are made when deemed important. Three classifications are used to separate these references by their order of importance. WARNING is used in connection with a procedure or situation that may result in serious injury or death. CAUTION is used in connection with a procedure or situation that will result in damage to the product. NOTE is used to emphasize important information.
FIOH, Laajaniityntie 1, FIN-01620 Vantaa, Finland, notified body no.0430, has EC type-examined this type of personal protective equipment. This instrument must be serviced by an authorized dealer every second year or after 500 dives (whichever comes first). See chapter 6. PrEN 13319 PrEN 13319 "Diving accessories - Depth gauges and combined depth and time measuring devices - Functional and safety requirements, test methods" is a European diving depth gauge standard draft.
WARNING Read this manual. Carefully read this instruction manual in its entirety paying close attention to all warnings listed below, including chapter 1.1. "Safety Precautions". Make sure that you fully understand the use, displays and limitations of the dive computer because any confusion resulting from neglecting to follow this instruction manual or from improper use of this device may cause a diver to commit errors that may lead to serious injury or death. WARNING Not for professional use.
WARNING There is always a risk of decompression illness (dci) for any dive profile even if you follow the dive plan prescribed by dive tables or a dive computer. no procedure, dive computer or dive table will prevent the possibility of dci or oxygen toxicity. An individual's physiological make up can vary from day to day. The dive computer cannot account for these variations. You are strongly advised to remain well within the exposure limits provided by the instrument to minimize the risk of DCI.
WARNING Perform prechecks. Always activate and check the device before diving in order to ensure that all Liquid Crystal Display (LCD) segments are completely displayed, that the device has not run out of battery power, and that the oxygen, altitude and personal adjustments are correct. Also, exit the Data Transfer mode before diving, as the computer does not automatically revert to Dive mode from Data Transfer mode. WARNING You are advised not to fly any time the computer counts down the no-flying time.
WARNING Do not dive with a cylinder of enriched air if you have not personally verified its contents and entered the analyzed value into your dive computer. Failure to verify cylinder contents and enter the appropriate O2% into your dive computer will result in incorrect dive planning information. WARNING The dive computer will not accept fractional percentage values of oxygen concentration. do not round up fractional percentages. For example, 31.8% oxygen should be entered as 31%.
WARNING Set the correct Personal Adjustment Mode. Whenever it is believed that factors that tend to increase the possibility of DCI exist, it is recommended that you use this option to make the calculations more conservative. Failure to select the correct Personal Adjustment Setting will result in erroneous dive and planning data. WARNING Freediving after scuba diving is not recommended.

1. INTRODUCTION Congratulations on your purchase of the SUUNTO STINGER advanced dive computer. The Stinger builds on the Suunto tradition of delivering feature-rich dive computers. The Stinger provides many new and enhanced features that cannot be found in any other dive computer. Push button controls access a wide selection of choices. The display is optimized for the dive mode chosen and it incorporates the patented user definable display field.
CONTINUOUS DECOMPRESSION WITH SUUNTO RGBM The Suunto Reduced Gradient Bubble Model (RGBM) utilized in the Stinger predicts both dissolved and free gas in blood and tissues of divers. It is a significant advance on the classic Haldane models, which do not predict free gas. The advantage of Suunto RGBM is additional safety through its ability to adapt to a variety of situations and dive profiles.
Diving with enriched air mixtures (nitrox) exposes the user to risks different from those associated with diving with standard air. These risks are not obvious and require training to understand and avoid. Risks include possible serious injury or death. Do not attempt to dive with any gas mix other than standard air without first receiving certified training in this specialty. 1.1.1.
1.1.3. NITROX Diving with nitrox provides the diver with an opportunity to reduce the risk of decompression illness by reducing the nitrogen content in the breathing gas mix. However, when the gas mix is altered, the oxygen content of the mix is generally increased. This increase exposes the diver to an oxygen toxicity risk not usually considered in recreational diving.
Therefore, provided the effort involved in freediving has not been severe, there is little risk in diving after breathhold diving. However, the converse is more unknown and may increase significantly the risk of DCI. Therefore, FREEDIVING AFTER SCUBA DIVING IS NOT RECOMMENDED. You should avoid freediving and not exceed five meters [16 ft] for at least two hours after scuba diving. Suunto also recommends you to be trained in freediving technique and physiology before conducting breathhold dives.
2. GETTING ACQUAINTED 2.1. FUNCTIONS The STINGER Advanced Computer Watch is a multipurpose dive instrument and a sport watch featuring several watch and dive computer modes. You can select the dive computer model between the Regular Air Dive Computer (AIR), Enriched Air Nitrox Dive Computer (EAN) and Freediving computer / Depth Gauge with Timer mode (FREE). The Air/EAN and Free modes can also be disabled (set to OFF) and the instrument can be used as a sports watch on land or in water. 2.2.
To select the display in the Logbook Mode press the select button. To select the dive planning mode in the dive surface modes. To make a special bookmark in the profile memory during a dive and to operate the timer in the Gauge mode. To show the date, seconds or dual time in the time keeping display press the + or - button. In the Setting Mode to increase the value press the + button to decrease the value press the - button. To operate the stopwatch see chapter 2.4.2.
NOTE: Water or moisture build-up around the water contact may cause the contact to activate automatically. This can happen, e.g., when washing your hands or sweating. If the water contact activates in the Time Mode, an ACW text will appear on display (Fig. 2.3.), and it will be shown until the water contact deactivates, or the Stinger enters the Dive Mode automatically. To save the battery power, you should deactivate the water contact by cleaning it and/or drying it with a soft towel. 2.4.
2.4.1. TIMEKEEPING DISPLAY The timekeeping display is the primary display of the Stinger (Fig. 2.5.). When the Time Mode is entered from other modes, the timekeeping display activates within two seconds, if no button is operated. In other modes (except in the Diving or Stopwatch Modes), if no button is operated within 5 minutes, the Stinger beeps and returns to the timekeeping display automatically. Fig. 2.4. The Time Mode is indicated by the TIME text and a mode indicator.
When diving, the dive entry time and date is registered in the Logbook Memory. Remember always to check before diving that the time and date are correctly set, especially when traveling to different time zones. 2.4.2. STOPWATCH [TIMER] The Stopwatch function is entered by pressing the S button, when the time keeping display is shown. The text TIMEr at the bottom and the mode indicator (TIME) on the left side of the display indicate that you have entered the Stopwatch function (Fig. 2.6.).
Use the + and - buttons to operate the elapsed time measurement, split time measurement or the times of two runners as follows: (ODSVHG WLPH PHDVXUHPHQW 6SOLW WLPH PHDVXUHPHQW 7LPHV RI WZR UXQQHUV 6WDUW 6WDUW 6WDUW 6WRS 6SOLW 6SOLW WLPH RI WKH ILUVW UXQQHU 5HVWDUW 6SOLW UHOHDVH 6WRS 6WRS 6WRS 6SOLW UHOHDVH WLPH RI WKH VHFRQG UXQQHU &OHDU &OHDU &OHDU Diving with the Stinger or data transfer will stop the stopwatch.
3. DIVING WITH THE STINGER In order to familiarize yourself with the menu based functions, Suunto recommends you use your Quick Reference Guide supplied with the Stinger together with the information in the following chapters. This section contains instructions on how to operate the dive computer and interpret its displays. You will find that this dive computer is easy to use and read. Each display shows only the data relevant to that specific diving situation. Fig. 3.1. Chosen Dive Mode. Chapter 3.1.
a) 3.1 BEFORE DIVING 3.1.1. ACTIVATION AND PRECHECKS b) c) The instrument can be activated by pressing the M button or it will activate the scuba dive computer mode (default) or freedive mode according the user selection, if submerged deeper than 0.5 m (1.5 ft). The chosen Dive Mode is indicated by the Air, EAN or Free texts and mode indicator on the right side of the display (Fig. 3.1.). Next, all display elements will turn on showing mostly figure 8's and graphical elements (Fig. 3.2.).
the instrument displays correct temperature and depth (0.0 m [0 ft]) the buzzer beeps you have preset desired displays on the User Definable Display Field the altitude and personal adjustment settings are correct (Air and EAN modes) m SURF TIME DIVE TIME °C TIME And if set to EAN mode, make sure that: the oxygen percentage is adjusted according to the measured Nitrox blend in your cylinder the oxygen partial pressure limit is set correctly. Fig. 3.4. Startup III. Surface mode (Air).
After activation of the Dive Mode or after diving, the Stinger will automatically switch to show the time keeping display within 5 minutes to conserve the battery power, if you do not press any buttons. However, the dive computer functions will remain active until it has calculated that all residual nitrogen has off-gassed. This may take up to 100 hours, as described in chapter 7.1. "Operating Principles".
TABLE 3.1. BATTERY POWER INDICATOR Display Operation Figure 3.3 BAT + 4 segments Normal, full battery. a) BAT + 3 segments Normal, battery power is getting low or the temperature is low. Battery replacement is recommended if you are going to colder conditions or if you are planning to make a dive trip. b) BAT + LOW + Battery power is low and the battery 2 segments + replacement is recommended. low battery symbol The battery symbol is displayed. The backlight is disabled.
After the battery check the Low Battery Warning is indicated by the battery symbol (Fig. 3.6.). If the battery symbol is displayed in the Surface mode or if the display is faded or weak, the battery may be too low to operate the dive computer and battery replacement is recommended. Fig. 3.6. Low Battery Warning. Battery symbol indicates that the battery is low and battery replacement is recommended.
The displays can be preset in the Surface Mode. If it is not active, enter it by selecting the Dive Mode. The preset display will remain active until another display is selected. The preset displays will be the default displays in the Diving Mode. The other available display can be accessed by pressing the + or - button. After five seconds the display changes back to the default preset display automatically. 3.1.3.1. PRESETTING TIME ALARM The alarm clock is set in the Setting Mode, ALM.
3.2. SCUBA DIVING 3.2.1. DIVING WITH AIR 3.2.1.1. DIVE PLANNING [PLAN] It is possible at any time in the Air/EAN Surface Mode to enter the Planning Mode, simply by pressing the S button. After showing the text PLAN and the mode indicator (Fig. 3.8.), the display will show the no-decompression limit for the depth of 9 m [30 ft].
The Planning mode also accounts for the following information from previous dives: any calculated residual nitrogen all dive history for the past four days oxygen exposure (EAN mode) The no-decompression times given for different depths will therefore be shorter than before your first "fresh" dive. DIVE NUMBERING SHOWN DURING DIVE PLANNING Fig. 3.8. Dive Planning. The Planning mode is indicated by the PLAN text and mode indicators.
3.2.1.2. PRESETTING THE DISPLAYS IN THE AIR MODE Preset with the - button in the lower left corner of the display (Fig. 3.4.): Fig. 3.10. Dive has just begun. Available no-decompression time is more than 199 min. the maximum depth or the temperature. Preset with the + button in the lower right corner of the display (Fig. 3.4.): the dive time or the current time. 3.2.1.3. BASIC DIVE DATA The dive computer will remain in the Surface mode at depths less than 1.2 m [4 feet].
During a no-decompression stop dive, the following information will be displayed (Fig. 3.11.): your present depth in meters [ft] the Altitude Adjustment setting on the right side of the center window with a wave and mountain symbols (A0, A1, or A2) (see Table 3.3.) the Personal Adjustment setting on the right side of the center window with a diver symbol and + signs (P0, P1, or P2) (see Table 3.4.) the available no-decompression time in minutes in the center window as NO DEC TIME.
3.2.1.4. SAFETY STOPS Safety stops are widely considered "good diving practice" and are an integral part of most dive tables. Reasons to perform a safety stop include a reduction in sub clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. Fig. 3.12. A three minute Recommended Safety Stop. The Stinger displays two different types of safety stops: Recommended Safety Stop and Mandatory Safety Stop. The Safety Stops are indicated by: Fig. 3.13. Mandatory Safety Stop.
3.2.1.4.1. RECOMMENDED SAFETY STOP With every dive over 10 meters the instrument has a three minute countdown for the recommended safety stop, to be taken in the 3 - 6 meter [10 ft - 20 ft] range. This is shown with the STOP sign and a three-minute countdown in the center window instead of the no-decompression time (Fig. 3.12.). The Recommended Safety Stop, as the name implies, is recommended. If it is ignored, there is no penalty applied to the following surface intervals and dives. 3.2.1.4.2.
Fig. 3.14. Violated Mandatory Safety Stop. Downward pointing arrow and an audible alarm indicate you should descend to ceiling zone. 36 You must not ascend shallower than 3 m [10 ft] with the Mandatory Safety Stop warning on. If you ascend above the Mandatory Safety Stop ceiling, a downward pointing arrow will appear and a continuous beeping starts (Fig. 3.14.). You should immediately descend to, or below, the Mandatory Safety Stop ceiling depth.
3.2.1.5. ASCENT RATE INDICATOR The ascent rate is shown graphically along the left side of the display as follows: TABLE 3.2. ASCENT RATE INDICATOR Ascent Rate Indicator The equivalent ascent speed Example in Fig. No segments Below 4 m/min [13 ft/min] 3.10 One segment 4 - 6 m/min [13 - 20 ft/min] 3.11 Two segments 6 - 8 m/min [20 - 26 ft/min] 3.12 Three segments 8 - 10 m/min [26 - 33 ft/min] 3.13 Four segments 10 - 12 m/min [33 - 39 ft/min] 3.
Fig. 3.15 Ascent Rate Indicator. Blinking SLOW and four segments are shown together with an audible alarm: ascent rate is more than 10 m/min [33 ft/ min]. This is a caution to slow down! STOP sign means that you are advised to make a Mandatory Safety Stop when you reach a depth of 6 m [20 ft]. 38 Whenever the SLOW warning segment and the STOP sign appear (Fig. 3.15.), you should immediately slow down your ascent.
3.2.1.6. DECOMPRESSION DIVES When your NO DEC TIME becomes zero, your dive becomes a decompression stop dive, i.e. you must perform one or several decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by a CEILING and blinking ASC TIME notation and an upward pointing arrow (Fig. 3.17.). If you exceed the no-decompression limits on a dive, the dive computer will provide decompression information required for ascent.
The ascent time (ASC TIME) is the minimum amount of time needed to reach the surface in a decompression dive. It includes: time needed to ascend to the ceiling at an ascent rate of 10 m/min [33 ft/ min] plus time needed at the ceiling. The ceiling is the shallowest depth where decompression could be made plus time needed at the Mandatory Safety Stop (if any) plus 3 minute Recommended Safety Stop plus time needed to reach the surface after the ceiling and safety stops have been completed.
CEILING, CEILING ZONE, FLOOR AND DECOMPRESSION RANGE When in decompression, it is important that you understand the meaning of ceiling, floor, and decompression range (Fig. 3.16.): The ceiling is the shallowest depth where decompression could be made. At this depth, or below, you must perform all stops. The ceiling zone is the optimum decompression stop zone. It is the zone between the minimum ceiling and 1.8 m [6 ft] below the minimum ceiling.
When conditions are rough, it may be difficult to maintain a constant depth near the surface. In this case it will be more manageable to maintain an additional distance below the ceiling, to make sure that the waves do not lift you above the ceiling. Suunto recommends that decompression takes place deeper than 4 m [13 ft], even if the indicated ceiling is shallower. Fig. 3.17. Decompression dive, below floor. Upward pointing arrow, blinking ASC TIME label and an audible alarm tell you to ascend.
DISPLAY BELOW THE FLOOR The blinking ASC TIME and an upward pointing arrow indicate that you are below the floor (Fig. 3.17.). You should start your ascent immediately. The ceiling depth is shown on the left and the minimum total ascent time on the right side of the center window. DISPLAY ABOVE THE FLOOR When you ascend above the floor, the ASC TIME display stops blinking and the upward pointing arrow disappears (Fig. 3.18.). Decompression will now begin, but is very slow.
only after the ASC TIME and CEILING labels have disappeared, which means that the decompression stop and any Mandatory Safety Stop has been completed. You are advised, however, to stay until the STOP sign has also gone. This indicates that the three minute Recommended Safety Stop has also been completed. DISPLAY ABOVE THE CEILING Fig. 3.20. Decompression dive, above ceiling. Note downward pointing arrow, Er warning and an audible alarm. You should immediately (within 3 minutes) descend to or below ceiling.
3.2.2. DIVING WITH EAN (NITROX) 3.2.2.1. BEFORE DIVING This dive computer can be set for diving with standard air only (Air mode) or it can be set for diving with Enriched Air Nitrox (EAN mode). If set to the EAN mode, the correct oxygen percentage of the gas in your cylinder must always be entered into the computer to ensure correct nitrogen and oxygen calculations. The dive computer adjusts its mathematical nitrogen and oxygen calculation models according to the entered O2% value (Fig. 3.21.).
3.2.2.2. PRESETTING THE DISPLAYS IN THE EAN MODE MAX When entering the EAN mode the oxygen percentage and partial pressure are always the default displays in the lower part of the display. Preset with the - button in the lower left corner of the display (Fig. 3.22.): Fig. 3.21. Nitrox display. Maximum depth based on set O2% (21%) and PO2 (1.4 bar) is 54.1 m [177 ft]. Preset with the + button in the lower right corner of the display (Fig. 3.22.): Fig. 3.22. Diving in EAN mode.
3.2.2.3. OXYGEN DISPLAYS If set to EAN mode the NITROX display, with all labeled oxygen information, is shown immediately after activation. The nitrox display shows (Fig. 3.21.
3.2.2.4. OXYGEN LIMIT FRACTION (OLF) In addition to tracking the diver's exposure to nitrogen, the instrument tracks the exposure to oxygen. These calculations are treated as entirely separate functions. The dive computer calculates separately for Central Nervous System oxygen toxicity (CNS) and Pulmonary Oxygen toxicity, the latter measured by the addition of Oxygen Toxicity Units (OTU). Both fractions are scaled so that the maximum tolerated exposure for each is expressed as 100%.
3.2.3. AT THE SURFACE 3.2.3.1. SURFACE INTERVAL AFTER AN AIR/EAN DIVE An ascent to any depth shallower than 1.2 m [4 ft] will cause the DIVING display to be replaced by the alternating SURFACE displays, giving the following information (Fig. 3.24. and 3.25.
Or in the lower display according the selection and mode: Fig. 3.24. Surface display. You have surfaced from a 18 minute dive, which maximum depth was 20.0 m [66 ft]. The present depth is 0.0 m [0 ft] and surface interval time is 0. Airplane symbol indicates that you should not fly and diver attention symbol indicates that you should prolong your surface interval time because of excess micro-bubbles. 50 dive time of most recent dive in minutes labeled with DIVE TIME.
3.2.3.2. DIVER ATTENTION SYMBOL The Diver Attention Symbol is an advice to extend surface interval. Some patterns of diving, in particular multiday diving with many dives and short surface intervals, cumulatively add a higher risk of DCI. When this is detected in addition to adapting the decompression algorithm, the Diver Attention Symbol is shown. 3.2.3.3.
the dive time will begin where it left off. After 5 minutes on the surface, subsequent dives are, by definition, repetitive. The dive counter displayed in the Planning Mode will increment to the next higher number if another dive is made. 3.2.3.4. FLYING AFTER DIVING The no-flying time is shown in the center window next to the airplane image. Flying or travelling to a higher altitude should be avoided at any time the computer counts down the no-flying time.
If a diver had less than 2 hours total accumulated dive time in the last 48 hours, then a 12 hour surface interval before flying is recommended. Following any dive that required a decompression stop, flying should be delayed for at least 24 hours, and if possible, for 48 hours. Suunto recommends that flying is avoided until all the DAN and UHMS guidelines and the dive computer wait to fly conditions are satisfied. 3.2.4.
TABLE 3.3. ALTITUDE ADJUSTMENT RANGES $OWLWXGH PRGH 6\PERO RQ GLVSOD\ $OWLWXGH UDQJH $ P > IW@ $ P > IW@ $ P > @ The entered Altitude Adjustment Mode is indicated by mountain symbols (A0, A1 = one mountain, or A2 = two mountains). Also, the maximum altitudes are displayed for each Altitude group (see Table 3.3.). Chapter 4.6. describes how the Altitude Mode is adjusted.
3.2.4.2. PERSONAL ADJUSTMENT There are adverse personal factors for DCI which divers can predict in advance and input into the decompression model. Factors that may affect susceptibility to decompression illness vary between divers and also for the same diver from one day to another. The three-step Personal Adjustment Mode is available, if a more conservative dive plan is desired.
This feature should be used to adjust the computer to be more conservative, according to personal preference, by entering the suitable Personal Adjustment Mode with the help of Table 3.4. In ideal conditions, retain the default setting, P0. If conditions are more difficult or other mentioned factors which tend to increase the possibility of DCI exist, select P1 or even the most conservative P2.
3.2.5. ERROR CONDITIONS The dive computer has warning indicators that alert the user to react to certain situations that would significantly increased the risk of DCI. If you do not respond to its warnings, the dive computer will enter an Error Mode, indicating that the risk of DCI has greatly increased. If you dive sensibly, it is very unlikely you will ever put the instrument into the Error Mode. OMITTED DECOMPRESSION The Error Mode results from omitted decompression, i.e.
3.3. FREE / GAUGE MODE 3.3.1. BEFORE DIVING IN THE FREE/GAUGE MODE If set to Free/Gauge mode, the dive computer can be used for freediving or diving with technical diving mixed gases. If you are trained for free or technical diving and you plan to use Free/Gauge mode on a regular basis, it may be preferable to disable the Air/EAN mode to set the instrument permanently to its Free/Gauge mode (see chapter 4.3.).
NOTE: The number of hours of dive time available depends on the sampling rate. A computer set to record depth every 4 seconds will fill its memory sooner than the same computer set to 30 seconds. The number of available hours also depends on the length of each dive. Fewer longer dives means more total hours of dive time available in the memory than does a large number of short dives.
m 3.3.2. PRESETTING THE DISPLAYS IN THE FREE/GAUGE MODE Preset with the - button in the lower left corner of the display (Fig. 3.28.) DIVE TIME °C Fig. 3.28. Surface display/ Alternative display. m DIVE °C Fig. 3.29. Free dive. Present depth is 6.1 m, dive time 1.03 min and dive number is 1. 60 the maximum depth or the temperature. Preset with the + button in the lower right corner of the display (Fig. 3.28.) the dive time, the current time or the dive number. 3.3.3.
3.3.3.1. FREEDIVING DAY HISTORY It is possible at any time in the Free Surface Mode to enter the Freediving Day History Mode, simply by pressing the S button. After showing the text DAY HIS and the mode indicator (Fig. 3.30.), the display will show (Fig. 3.31.): the total amount of free dives, the longest free dive in minutes and seconds in the center window and the deepest free dive made during that day. Fig. 3.30. Freediving Day History.
3.3.4. GAUGE MODE The Free mode automatically changes to Gauge mode when the dive time exceeds five minutes for a single dive. In addition to the displays shown in the Free mode the Ascent Rate indicator is now enabled. In the Free/Gauge mode the Dive Time in the center window can also be used as an automatic Stop Watch. When the SELECT button is pressed during the dive: Fig. 3.32. Surface display after Free dive. Center window showing surface time.
3.3.5. SURFACE INTERVAL AFTER A FREE/GAUGE DIVE An ascent to any depth shallower than 1.2 m [4 ft] will cause the DIVING display to be replaced by the SURFACE display, giving the following information (Fig. 3.32. and 3.34.): maximum depth of most recent dive in meters [ft] present depth in meters [ft] the surface time in hours and minutes (separated by a colon), telling the duration of the present surface interval. m Fig. 3.34. Surface display after Gauge dive. Center window showing surface time.
AFTER A SCUBA DIVE IN THE GAUGE MODE: the no-flying time in hours and minutes is shown next to the airplane in the center window of the display (Fig. 3.35.) no-flying warning indicated by an airplane icon. Or in the lower display according the selection: dive time of the most recent dive in minutes labeled with DIVE TIME. the current time labeled with TIME the dive number labeled with DIVE maximum depth labeled with MAX the current temperature with °C for Centigrade [or °F for Fahrenheit].
3.4. AUDIBLE AND VISUAL ALARMS The dive computer features audible and visual alarms to advise when important limits are approached or to acknowledge preset alarms. A short single beep occurs when: when the dive computer automatically returns to the Time mode. Three single beeps with a two second interval and the backlight activated for 5 seconds occur when: the no-decompression dive turns into a decompression stop dive.
You are able to preset alarms before the actual dive. The user programmable alarms can be set for maximum depth, dive time and daily time. The alarms activate when: The preset maximum depth is reached - continuous beep series for 24 seconds or until any button is pressed. - the maximum depth blinks as long as the present depth value exceeds the adjusted value. The preset dive time is reached - continuous beep series for 24 seconds or until any button is pressed.
Continuous beeps for 3 minutes and the backlight activated for 5 seconds occur when: the set oxygen partial pressure limit is exceeded. The maximum depth is replaced with the current blinking PO2 value. You should immediately ascend above the PO2 depth limit (Fig. 3.23.).
4. SETTING MODE [SET] The time, date, dual time, daily alarm, scuba and free dive selections and settings, dive time and depth alarms and the altitude, personal and unit adjustments are set in the Setting Mode (Fig. 4.1.). Fig. 4.1. The Setting Mode is indicated by the SET text and mode indicator. Enter the Setting Mode from other modes by pressing the M button.

5. MEMORIES AND DATA TRANSFER [MEM] The memory functions for the Stinger include the combined Logbook and Dive Profile Memory, Dive History Memories for scuba and free dives and the Data Transfer and PC-Interface functions. NOTE: After diving, the memory mode cannot be accessed until 5 minutes after the dive. Fig. 5.1. Memory Mode. Enter the Memory Mode [MEM] from other modes by pressing the M button.
5.1. LOGBOOK AND DIVE PROFILE MEMORY [LOG] Fig. 5.3. Logbook, page I. This instrument has a very sophisticated high capacity Logbook and Profile Memory. The data is recorded to the profile memory based on the selected sampling rate. Dives shorter than the recording interval are not registered. You have the possibility to set the scuba diving sampling rate to 10, 20, 30 or 60 seconds with the optional PC-interface unit and software.
The data of the most recent dive is shown first. The END text is displayed after the oldest and most recent dive (Fig. 5.7.). The following information will be shown on four pages: Page I, main display (Fig. 5.3.) dive number in the dive series, Air/EAN dives are indicated by a D number and Free/Gauge by a F number dive entry time and date. Page II (Fig. 5.4.

6. CARE AND MAINTENANCE This Suunto dive computer is a sophisticated precision instrument. Though designed to withstand the rigors of scuba diving, you must treat it with proper care and caution as any other precision instrument. 6.1. CARE OF YOUR STINGER NEVER try to open the case of the Stinger or to remove the buttons. NEVER try to open the depth sensor cover. Every two years or after 500 dives (whichever comes first) have your Stinger serviced by an authorized dealer or distributor.
90 Check the spring bars holding the strap and the buckle for flaws. If the flexibility of the spring bars has reduced, have them replaced immediately by your SUUNTO dealer or distributor. Wash and rinse the unit in fresh water after every use. Particularly clean the water contact carefully. Protect the unit from shocks, extreme heat or direct sunlight and chemical attack.
6.2. MAINTENANCE If left without care for an extended period, a thin film (often invisible to the eye) will cover the unit. Much like the buildup on the glass of an aquarium, this film is the result of organic contaminates found in both salt and fresh water. Suntan oil, silicone spray and grease will speed up this process. As a result of this buildup, moisture will be trapped next to the water contact and will not allow your Stinger to operate properly.
6.3. WATER RESISTANCE INSPECTION Water resistance of the unit must be checked after replacement of the battery, mineral crystal window or buttons. The check requires special equipment and training. You must frequently check the mineral crystal window for leaks. If you find moisture inside your advanced computer watch, there is a leak. A leak must be corrected without delay, as moisture will seriously damage the unit, even beyond repair.
7. TECHNICAL DESCRIPTION 7.1. OPERATING PRINCIPLES NO-DECOMPRESSION LIMITS The no-decompression limits displayed by the dive computer for the first dive to a single depth (see Table 7.1. and 7.2.), are slightly more conservative than those permitted by the U.S. Navy tables. TABLE 7.1.
TABLE 7.2.
ALTITUDE DIVING The atmospheric pressure is lower at high altitudes than at sea level. After traveling to a higher altitude, the diver will have additional nitrogen in his body, compared to the equilibrium situation at the original altitude. This "additional" nitrogen is released gradually in time and equilibrium is reached. It is recommended that you adapt to the new altitude by waiting at least three hours before making a dive.
7.2. REDUCED GRADIENT BUBBLE MODEL, SUUNTO RGBM The Suunto Reduced Gradient Bubble Model (RGBM) is a modern algorithm for predicting both dissolved and free gas in the tissues and blood of divers. It was developed in a co-operation between Suunto and Bruce R. Wienke BSc, MSc. PhD. It is based on both laboratory experiments and diving data, including data from DAN. It is a significant advance on the classical Haldane models, which do not predict free gas (microbubbles).
SUUNTO RGBM ADAPTIVE DECOMPRESSION The Suunto RGBM algorithm adapts its predictions of both the effects of microbubble build-up and adverse dive profiles in the current dive series. It will also change these calculations according to the personal adjustment you select. The pattern and speed of decompression at the surface is adjusted according to microbubble influence. Also on repetitive dives adjustment may be applied to the maximum allowable nitrogen overpressure in each theoretical tissue group.
DIVER ATTENTION SYMBOL - ADVICE TO EXTEND SURFACE INTERVAL Some patterns of diving cumulatively add a higher risk of DCI, e.g. dives with short surface intervals, repetitive dives deeper than earlier ones, multiple ascents, substantial multiday diving. When this is detected in addition to adapting the decompression algorithm Suunto RGBM will in some circumstances also advise, with the Diver Attention Symbol (review chapter 3.2.3.2.) that the diver extend the surface interval. 7.3.
The oxygen related data and warnings are provided at all appropriate phases of a dive. The following information will be shown before and during a dive, when the computer is set in EAN mode: the selected O2% the color-coded OLF% bar graph for either CNS% or OTU% audible alarms are given and the OLF bar graph starts to blink when the 80% and 100% limits are exceeded the blinking of the bar graph stops, when the PO2 is below 0.

9. GLOSSARY Altitude dive A dive made at an elevation greater than 300 m [1000 ft] above sea level. Apnea Absence of breathing. Freedivers are apneic throughout the duration of their dive. Ascent rate The speed at which the diver ascends toward the surface. ASC RATE Abbreviation for ascent rate. Ascent time The minimum amount of time needed to reach the surface on a decompression stop dive. ASC TIME Abbreviation for ascent time.
Central Nervous System Toxicity Toxicity caused by oxygen. Can cause a variety of neurological symptoms. The most important of which is an epileptic-like convulsion which can cause a diver to drown. CNS% Central Nervous System toxicity limit fraction. See note "Oxygen Limit Fraction". Compartment See "Tissue group". DAN Divers Alert Network. DCI Abbreviation for decompression illness.
Dive time Elapsed time between leaving the surface to descend, and returning to the surface at the end of a dive. EAD Abbreviation for equivalent air depth. EAN Abbreviation for enriched air nitrox. Enriched Air Nitrox Also called Nitrox or Enriched Air = EANx. Air that has some oxygen added. Standard mixes are EAN32 (NOAA Nitrox I = NN I) and EAN36 (NOAA Nitrox II = NN II). Equivalent Air Depth Nitrogen partial pressure equivalent table.
Hyperventilation An increase in rate and/or volume of breathing. Carbon dioxide blood levels decrease with little corresponding increase in oxygen blood levels. If the diver engages in excessive hyperventilation, he may diminish his desire to breathe, long enough to become unconscious after a long period of apnea. Hypoxia A condition that occurs when a diver's tissues do not receive enough oxygen.
No-decompression dive Any dive which permits a direct, uninterrupted ascent to the surface at any time. NO DEC TIME Abbreviation for no-decompression time limit.

Oxygen Tolerance Unit Is used to measure the Whole-Body-Toxicity. Oxygen Limit Fraction A term used by SUUNTO for the values displayed in the Oxygen Toxicity bar graph.
Oxygen partial pressure Limits the maximum depth to which the used Nitrox mixture can safely be used. The maximum partial pressure limit for enriched air diving is 1.4 bar. The contingency partial pressure limit is 1.6 bar. Dives beyond this limit have the risk for immediate oxygen toxicity. PO2 Abbreviation for oxygen partial pressure. Suunto RGBM Abbreviation for Suunto Reduced Gradient Bubble Model.
Static apnea blackout Unconsciousness due to gradual oxygen depletion caused by holding one's breath too long. It can occur anywhere, particularly at the surface, and is not associated with depth or pressure changes. It commonly occurs in swimming pools at the surface or during long underwater endurance swims. SURF TIME Abbreviation for surface interval time. Surface interval time Elapsed time between surfacing from a dive and beginning a descent for the subsequent repetitive dive.
