Not for professional use. Suunto dive computers are intended for recreational use only. The demands of commercial or professional diving may expose the diver to depths and exposures that tend to increase the risk of decompression illness (DCI).
DCI. As an added measure of safety, you should consult a physician regarding your ﬁ tness 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 % and a maximum PO Dives with required decompression stops are not recommended.
Perform pre-checks. Always activate and check the device before diving in order to ensure that all Liquid Crystal Display (LCD) segments are completely dis played, 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.
Do not dive with a cylinder of enriched air if you have not personally veriﬁ ed its contents and entered the analyzed value into your dive computer. Failure to verify cylinder contents and enter the appropriate O will result in incorrect dive planning information. The dive computer will not accept fractional percentage values of oxygen concentration.

1. INTRODUCTION Congratulations on your purchase of the SUUNTO MOSQUITO advanced wristop dive computer. The Mosquito builds on the Suunto tradition of delivering feature- rich dive computers, providing different operating modes for different types of diving. Push button controls access a wide selection of choices. The display is optimized for the dive mode chosen and it incorporates a patented user deﬁ...
Recommended Safety Stop is included. The combination of stop types will depend on the speciﬁ c dive situation. To get the most from the safety beneﬁ ts be sure to read the summary of the Suunto Reduced Gradient Bubble Model in chapter 7.2.
Do not attempt to dive with any gas mix other than standard air without ﬁ rst receiving certiﬁ ed training in this specialty. 1.1.1. EMERGENCY ASCENTS In the unlikely event that Mosquito malfunctions during a dive, follow the emergency procedures provided by your certiﬁ ed dive training agency or, alternatively, STEP 1: Assess the situation calmly and then move promptly to less than 18 m [60 ft].
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.

• the oxygen partial pressure limit is set correctly. The Mosquito is now ready for diving. NOTE: The surface interval time does not run before the ﬁ rst dive. Fig. 3.4. Startup III. Surface mode (Air). Depth and dive time are zero.
After activation of the Dive Mode or after diving, the Mosquito 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.
TABLE 3.1. BATTERY POWER INDICATOR Temperature or an internal oxidation of the battery affects the battery voltage. If the instrument is stored for a long period, the low battery warning may be displayed even though the battery has enough capacity. The low battery warning may also be displayed at low temperatures, even though the battery has enough capacity in warmer conditions.
This Mosquito has several User Deﬁ nable Functions and depth and time related alarms that you can set according to your personal preference. For example the Mosquito has a patented presetting system for the User Deﬁ nable Display Field in the lower part of the display.

(Fig. 3.8.), the display will show the no-decompression limit for the depth of 9 m [30 ft]. By pressing the + button, the Mosquito will calculate and show the next deeper no-decompression limits in 3 m [10 ft] increments ending at 45 m [150 ft] or at the maximum allowed depth in the EAN mode.
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 ﬁ rst “fresh”...
Fig. 3.10. Dive has just begun. Available no-decompression time is more than 199 min. Fig. 3.11. Diving display. Present depth is 19.3 m [63 ft] and no-decompression stop time limit is 23 minutes in A0/P1 mode. Maximum depth during this dive has been 19.8 m [65 ft], elapsed dive time is 16 minutes.
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.) •...
Reasons to perform a safety stop include a reduction in sub clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. The Mosquito displays two different types of safety stops: Recommended Safety Stop and Mandatory Safety Stop. The Safety Stops are indicated by: •...
When the ascent rate exceeds 12 meters/min [40 ft] momentarily or 10 meters/min [33ft] continuously the micro-bubble build-up is predicted to be more than allowed for in the decompression model. The Suunto RGBM calculation model responds to this by adding a Mandatory Safety Stop to the dive. The time of this Mandatory Safety Stop will depend on the severity of the ascent rate excess.
Fig. 3.14. Violated Mandatory Safety Stop. Downward pointing arrow and an audible alarm indicate you should descend to ceiling zone. 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.
188.8.131.52. ASCENT RATE INDICATOR The ascent rate is shown graphically along the left side of the display as follows: TABLE 3.2.

184.108.40.206. 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.
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 •...
CEILING, CEILING ZONE, FLOOR AND DECOMPRESSION RANGE When in decompression, it is important that you understand the meaning of ceiling, ﬂ oor, 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. •...
DISPLAY BELOW THE FLOOR The blinking ASC TIME and an upward pointing arrow indicate that you are below the ﬂ oor (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.

18.104.22.168. 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).
3.2.3. AT THE SURFACE 22.214.171.124. 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.): •...

TABLE 3.3. ALTITUDE ADJUSTMENT RANGES 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.
184.108.40.206. 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.
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 difﬁ cult or other mentioned factors which tend to increase the possibility of DCI exist, select P1 or even the most conservative P2.
The Error mode will stay for 48 hours, during which time you should not dive. Whilst Mosquito is in Error mode the ASC TIME label will be displayed in the center window and the Planning Mode will be disabled.
If set to Free mode, the dive computer can be used for freediving or snorkeling. In the freediving mode the Mosquito provides depth, time and proﬁ le information and an accurate 2 second sampling interval for the logbook proﬁ le memory The Free mode is set using the SET DIVE function (See Chapter 4.3 Dive Mode Settings)

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. •...
Continuous beeps for 3 minutes and the backlight activated occur when: • the set oxygen partial pressure limit is exceeded. The maximum depth is replaced with the current blinking PO ascend above the PO When the oxygen limit fraction indicates that the maximum limit is reached, you must immediately ascend until the warning stops blinking! Failure to take action to reduce oxygen exposure after the warning is given can rapidly increase the risk of oxygen toxicity and the risk of injury or death.

7. TECHNICAL DESCRIPTION 7.1. OPERATING PRINCIPLES NO-DECOMPRESSION LIMITS The no-decompression limits displayed by the dive computer for the ﬁ rst 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.
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.
(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: •...
SUUNTO RGBM ADAPTIVE DECOMPRESSION The SUUNTO RGBM algorithm adapts its predictions of both the effects of micro-bubble build-up and adverse dive proﬁ les in the current dive series. It will also change these calculations according to the personal adjustment you select.
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 220.127.116.11.) that the diver extend the surface interval 7.3.
