Only divers trained in the proper use of scuba diving equipment should use a dive computer. No dive computer can replace the need for proper dive training. Insufficient or improper training may cause diver to commit errors that may lead to serious injury or death.
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. As an added measure of safety, you should consult a physician regarding your fitness before diving.
Suunto strongly recommends that sport divers limit their maximum depth to 40 m [130 ft] or to the depth calculated by the computer based on the selected O2% and a maximum PO2 of 1.4 bar settings.
Dives with required decompression stops are not recommended. you should ascend and begin decompression immediately when the dive computer shows you that a decompression stop is required. Note the blinking ASC TIME symbol and the upward pointing arrow.
Use back-up instruments. Make sure that you use back-up instrumentation including a depth gauge, submersible pressure gauge, timer or watch, and have access to decompression tables whenever diving with a dive computer.
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.
You are advised not to fly any time the computer counts down the no-flying time. always activate the computer to check the remaining no-fly time prior to flying. The computer goes into the stand-by display automatically 5 minutes after surfacing. Flying or traveling to a higher altitude within no-fly time can greatly increase the risk of DCI. Review the recommendations given by Diver's Alert Network (DAN) in chapter 3.2.3.4. "Flying After Diving". There can never be a flying after diving rule that is guaranteed to completely prevent decompression illness!

The dive computer should never be traded or shared between users while it is in operation. Its information will not apply to someone who has not been wearing it throughout a dive or sequence of repetitive dives. Its dive profiles must match that of the user. If it is left on the surface during any dive, it will give inaccurate information for subsequent dives. No dive computer can take into account dives made without the computer. Thus any diving activity up to four days prior to initial use of the computer may cause misleading information and must be avoided.
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.
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%. Rounding up will cause nitrogen percentages to be understated and will affect decompression calculations. If there is a desire to adjust the computer to provide more conservative calculations, use the personal adjustment feature to affect decompression calculations or reduce the PO2 setting to affect oxygen exposure.
Set the correct Altitude Adjustment Mode when diving at altitudes greater than 300 m [1000 ft] the Altitude Adjustment feature must be correctly selected in order for the computer to calculate the decompression status. The dive computer is not intended for use at altitudes greater than 3000 m [10000 ft]. Failure to select the correct Altitude Adjustment setting or diving above the maximum altitude limit will result in erroneous dive and planning data.
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.
Freediving after scuba diving is not recommended. It is recommended to avoid freediving for at least two hours and not to exceed five meters [16 ft] after scuba diving depending on your diving activity. Suunto also recommends you to be trained in freediving technique and physiology before conducting breath holding dives. No dive computer can replace the need for proper dive training. Insufficient or improper training may cause diver to commit errors that may lead to serious injury or death. NOTE: Free mode automatically changes to Gauge mode when the dive time exceeds five minutes for a single dive. If the Stinger is in Gauge mode it is not possible to set it to Air or EAN modes until 48 hours have passed. This does not apply to changing between Free and Air or EAN modes. Changing from Air to EAN mode is possible at any time. Changing from EAN to Air mode however requires you to wait until the no-flying time has counted down.

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. This dive computer is a compact and sophisticated multipurpose dive instrument, designed to give you years of troublefree service.

CHOICE OF DIVING AND WATCH MODES
User options for the Stinger are selected using the push buttons. Pre dive configuration and setup options include: Choice of operating mode - Air / Nitrox / Free/Gauge Maximum depth alarm Dive time alarm Mix Oxygen fraction % (Nitrox mode only) Oxygen partial pressure alarm limit Altitude adjustment Personal adjustment Choice of unit - Metric / Imperial Clock, calendar, daily alarm, stopwatch, dual time User definable display fields
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. In order to optimize how to respond to different added risk situations an additional category of stop, referred to as a Mandatory Safety Stop, has been introduced. Also a countdown for the Recommended Safety Stop is included. The combination of stop types will depend on the specific dive situation. To get the most from the safety benefits be sure to read the summary of the Suunto Reduced Gradient Bubble Model in chapter 7.2.

1.1. SAFETY PRECAUTIONS

Do not attempt to use Stinger without reading this instruction manual in its entirety, including all the warnings. Make sure that you fully understand the use, displays and limitations of the instrument. If you have any questions about the manual or the dive computer, contact your SUUNTO dealer before diving with the dive computer. Always remember that you are responsible for your own safety. When used properly, the dive computer is an outstanding tool for assisting properly trained, certified divers in planning and executing sport dives. It is not a substitute for certified scuba instruction, including training in the principles of decompression.
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.

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. No dive computer can replace the need for proper dive training. Insufficient or improper training may cause a diver to commit errors that may lead to serious injury or death.

2.3. WATER CONTACTS

The water contact is located on the right side of the case (Fig. 2.2.). When submerged the contact is connected to the case by the conductivity of the water and the Surface or Diving Mode is automatically activated. Contamination or dirt on the water contact may prevent this automatic operation. It is, therefore, important that the water contact is kept clean. The contact can be cleaned with fresh water and a soft brush (e.g. tooth brush).

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. TIME MODE [TIME]

The Stinger has dual time, calendar clock, stopwatch and alarm clock functions. The calendar clock and the stopwatch are operated in the Time Mode. The mode is indicated by the TIME text and the mode indicator in the display (Fig. 2.4.). The time, dual time, date and the daily alarm are set in the Setting Mode (see chapter 4).

3.1.3.2. PRESETTING DIVE ALARMS
The dive alarms (dive time alarm and maximum depth alarm) are set in the Setting Mode, DIVE AL. For further information see chapter 4.5.

3.1.4. BOOKMARK

It is possible to make special marks in the profile memory during a dive. These Bookmarks will be shown as a Diver Attention Symbol when scrolling the profile memory on the computer display (Fig. 3.7). The Bookmarks will also be shown as annotations in the PC-software, Suunto Dive Manager. To make a bookmark on the profile memory during a dive press the S button. The Diver Attention Symbol will be displayed to confirm the bookmark. In the Gauge mode pressing the S button also resets the stopwatch.

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]. By pressing the + button, the Stinger will calculate and show the next deeper nodecompression limits in 3 m [10 ft] increments ending at 45 m [150 ft] or at the maximum allowed depth in the EAN mode. By pressing the - button the next shallower depth will be shown again. The Planning Mode can be canceled by pressing the M or the S button. NOTE: The Planning mode is disabled in the Air/EAN Error mode (see chapter 3.2.5.). Higher Altitude and conservative Personal Adjustment Modes will shorten the nodecompression time limits. These limits at different Altitude and Personal Adjustment Mode selections are shown in Table 7.1. and 7.2.

DEFAULT NITROX SETTINGS

In the EAN mode, the default setting is for standard air (21% O2). It remains in this setting until the O2% is adjusted to any other percentage of oxygen (22% - 50%). If a dive is started within 2 hours Stinger retains this value until the dive series is finished. If unused, the computer will retain the manually entered value for the selected oxygen percentage for about two hours, after which it will revert to the default setting of 21% O2. The default setting for maximum oxygen partial pressure is 1.4 bar, however you are able to set it in the range of 1.2 - 1.6 bar.
3.2.2.2. PRESETTING THE DISPLAYS IN THE EAN MODE
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].
oxygen percentage (default) the maximum depth or the temperature.
Preset with the + button in the lower right corner of the display (Fig. 3.22.): current oxygen partial pressure the dive time or the current time.
Fig. 3.22. Diving in EAN mode. The O2% is set to 32%.

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.): oxygen percentage, labeled with O2%, is shown in the left side of the lower display set oxygen partial pressure limit, labeled with PO2, is shown in the right side of the lower display maximum allowed depth based on the set oxygen percentage and partial pressure limit current oxygen toxicity exposure shown with an Oxygen Limit Fraction (OLF) bar graph along the right side of the display.
In the Dive mode the current oxygen toxicity exposure is always shown with an Oxygen Limit Fraction (OLF) bar graph and the oxygen percentage labeled with O2%. The current oxygen partial pressure labeled with PO2 is also shown, if selected (Fig. 3.22.). During a dive, the oxygen partial pressure, labeled with PO2, is always shown instead of the preselected display, if the partial pressure is greater than 1.4 bar or the set value (Fig. 3.23.).

Fig. 4.4. The year, month and day is selected. Page II. Dual time selected. Page III. Fig. 4.3. The Time Adjustment Mode is activated and the second digits are blinking. Page I.

2. Wait two seconds until the Daily Alarm Setting Mode activates automatically. The time mode indicator appears and the alarm status [On/OFF] starts to blink on the display (Fig. 4.6.).
3. Press S to change the selection in the following sequence: -> On/OFF status -> hours -> minutes 4. While the alarm status [On/OFF] is selected (blinking) press + or - to change the status. When the alarm status is On, the daily alarm indicator ( -symbol) in the bottom right corner of the display indicates that the alarm is on. 5. Set the other sections as follows: While any other digits (except alarm status) are selected (blinking), press + to increase the value or - to decrease it. Holding down either button starts the scrolling of the current selection. The 12-hour or 24-hour format of the alarm matches the format of the timekeeping display, which is selected in the Time Adjustment Mode (see chapter 4.1.). When using the 12-hour format of the alarm, take care to set the time correctly as morning (AM) or afternoon (PM). 6. After you have set the daily alarm, press the M button to save the settings and to return to the Setting Mode [SET].
4.3. AIR AND ENRICHED AIR NITROX SETTINGS [EAN]
In this setting mode you can either select one scuba dive mode (standard air and enriched air nitrox) or disable both. If you select ON then you have a choice of whether to have either Standard Air or Enriched Air Nitrox as the operating option.

5.3. DATA TRANSFER AND PCINTERFACE [TR-PC]
The Stinger can be connected to an IBM compatible personal computer (PC), using the optional SUUNTO PC-Interface and the SUUNTO DIVE MANAGER software. With the PC-Interface dive data from the Stinger can be downloaded to a PC. Data can be added to complete the logbook and paper copies of your dive log and profiles can easily be printed. The PC-Interface software can be used for educational and demonstration purposes, for planning dives, as well as for keeping complete record of your dive history with the Stinger.
The data transfer is carried out using the water contact of the Stinger. The following data is transferred to the PC: depth profile of the dive dive time preceding surface interval time dive number Altitude and Personal adjustment settings oxygen percentage setting and maximum OLF (in EAN mode) tissue calculation data temperature at the beginning of the dive, maximum depth and end of the dive dive entry time (year, month, day and time) additional dive information (e.g. SLOW and Mandatory Safety Stop violations, Diver Attention Symbol, Bookmarks, Surfaced Mark, Decompression Stop Mark, Ceiling Error Mark) dive computer serial number personal 30 character information.
It is also possible to manually add comments and other personal information to the PC based dive data files. The SUUNTO PC-Interface package comes complete with the interface unit, the software and an installation guide.

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. SUUNTO does not take any responsibility for damage caused by moisture in the Stinger, if the instructions of this manual are not carefully followed. In case of a leak immediately bring the Stinger to an authorized SUUNTO dealer or distributor.

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. NO-DECOMPRESSION TIME LIMITS (MIN) FOR VARIOUS DEPTHS (M) FOR THE FIRST DIVE OF A SERIES

'HSWK >IW@ 3HUVRQDO 0RGH $OWLWXGH 0RGH 3$ 3$ 3$ 3$ 3$ 3$ 3$ 3$ 3$

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. Before high altitude diving, the instrument must be set to the Altitude Adjustment mode to adjust the calculations for the new altitude. The maximum partial pressures of nitrogen allowed by the mathematical model of the dive computer are reduced according to the lower ambient pressure. As a result, the allowed no-decompression stop limits are considerably reduced.

SURFACE INTERVALS

The dive computer requires a minimum surface interval of 5 minutes between dives in the Air/EAN mode. If a surface interval is shorter than 5 minutes, the next dive is treated as a continuation of the previous dive. In the Free/Gauge mode this surface interval is equivalent to the sampling rate.
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). It incorporates consistency with real physical laws for gas kinetics. The advantage of Suunto RGBM is additional safety through its ability to adapt to a wide variety of situations. Suunto RGBM addresses a number of diving circumstances outside the range of just dissolved gas models by: Monitoring continuous multiday diving Computing closely spaced repetitive diving Reacting to a dive deeper than the previous dive Adapting for rapid ascents which produce high micro-bubble (silent-bubble) build-up.

Whole-Body Toxicity Another form of oxygen toxicity, which is caused by prolonged exposure to high oxygen partial pressures. The most common symptoms are irritation in the lungs, a burning sensation in the chest, coughing and reduction of the vital capacity. Also called Pulmonary Oxygen Toxicity. See also OTU.
