1. WELCOME TO THE WORLD OF SUUNTO DIVING INSTRUMENTS Suunto D9 was designed to help you get the most out of your diving. By reading this manual and becoming familiar with the functions of your dive computer, you can begin a new era in your diving - one in which all dive-critical data can be seen on your wrist.
Suunto D9 is the world’s first dive computer to integrate a digital compass, wireless tank data reception, and gas switching. It simplifies your diving experience because all the information you need relating to depth, time, tank pressure, decompression status, and direction is now available on one easy-to-read screen – not hanging off you in a tangle of different gauges.
2. WARNINGS, CAUTIONS, AND NOTES Throughout this manual, important safety icons are displayed.
WARNING 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 conditions that tend to increase the risk of decompression illness (DCI). Therefore, Suunto strongly recommends that the device is not used for any commercial or professional diving activities.
WARNING 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! WARNING DIVES THAT REQUIRE 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.
WARNING YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER COUNTS DOWN THE NO-FLY TIME. ALWAYS ACTIVATE THE COMPUTER TO CHECK THE REMAINING NOFLY TIME PRIOR TO FLYING! Flying or traveling to a higher altitude within the no-fly time can greatly increase the risk of DCI. Review the recommendations given by Diver’s Alert Network (DAN) in Section 7.1.4. Flying after diving.
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 SELECT THE CORRECT PERSONAL ADJUSTMENT SETTING! 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 This device contains a Lithium cell battery.
3. SUUNTO D9 AT A GLANCE NOTE 16 If no button is pressed for 5 minutes, the dive computer beeps and returns to the TIME mode automatically.
3.1. Navigating in the menus Suunto D9 has three main operating modes - TIME mode (TIME), DIVE mode (DIVE), and MEMORY mode (MEM) – as well as the COMPASS submode, which can be activated from either TIME or DIVE modes. To toggle between the main modes, press the MODE button. To select a submode in DIVE and MEM mode, press the UP/DOWN buttons.

ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 4.1.6. Setting the backlight Use the BACKLIGHT SETTING mode to turn the backlight on or off and to define how long it stays on for (5, 10, 20, 30, or 60 seconds). When the backlight is turned off, it does not illuminate when an alarm sounds. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 4.1.7. Setting the tones The TONE SETTING mode allows you to activate or deactivate the tones.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 4.2. Stopwatch The Suunto D9’s stopwatch measures elapsed and split times. A separate stopwatch (dive timer) can also be used when in GAUGE mode. See Section 6.3. Diving in GAUGE mode (DIVEgauge) . USE DOWN BUTTON TO START STOPWATCH AND TAKE A SPLIT TIME. THE UP BUTTON STOPS THE STOPWATCH AND LONG PRESSING IT RESETS IT.
4.3. AC water contacts The water and data transfer contact is located on the right side of the case. When submerged, the water contact is connected to the casing (which is the other pole of the water contact) by the conductivity of the water and the “AC” symbol appears on the display. The AC text is shown until the water contact deactivates. AC APPEARS IN THE TOP RIGHT CORNER OF THE DISPLAY, WHEN THE DIVE COMPUTER IS IN CONTACT WITH WATER. THIS ALSO ACTIVATES THE DIVE MODE.
NOTE Water or moisture build-up around the water contact may cause the contact to activate automatically. This can happen, for example, when washing your hands or sweating. If the water contact activates in the TIME mode, the AC symbol will appear on the display, and will be shown until the water contact deactivates. To save battery power, you should deactivate the water contact by cleaning it and/or drying it with a soft towel. 4.4.
IF ACCESSED FROM TIME MODE, TIME AND BEARING ARE DISPLAYED AT THE BOTTOM OF THE SCREEN. IF ACCESSED FROM DIVE MODE, CURRENT DEPTH AND TIME OR MAXIMUM DEPTH, AS WELL AS BEARING OR DIVE TIME OR TEMPERATURE ARE DISPLAYED. NOTE When accessed from DIVE mode, toggle between the alternative displays by pressing the UP/DOWN buttons. NOTE In order to save battery power, the compass display will automatically return to the TIME or DIVE mode 60 seconds after the last button-press. 4.4.1.
4.4.2. Locking a bearing A bearing can be locked to help you follow a selected course, and directional arrows point towards the locked bearing. Locked bearings are stored in the memory for later analysis and are available the next time the compass is activated. TO LOCK A BEARING, PRESS SELECT. The Suunto D9 also provides help for navigating square and triangular patterns, as well as navigating a return heading.
Symbol Explanation You are 120 (or 240) degrees from the locked bearing 4.4.3. Compass settings You can define the compass settings (declination and calibration) when in COMPASS mode: Declination You can compensate for the difference between true north and magnetic north by adjusting the compass declination. The declination can be found, for example, from sea charts or topographic maps of the local area. ADJUST WITH UP AND DOWN. ACCEPT WITH SELECT.
Calibration Because of changes in the surrounding magnetic field, the Suunto D9 electronic compass occasionally needs to be re-calibrated. During the calibration process, the compass adjusts itself to the surrounding magnetic field. As a basic rule, you should calibrate the compass whenever it doesn’t seem to operate properly, or after replacing the dive computer's battery. Strong electromagnetic fields, such as powerlines, stereo speakers, and magnets can affect the compass calibration.
If the calibration fails several times in a row, it is possible that you are in an area with sources of magnetism, such as large metal objects, powerlines or electric appliances. Move to another location and try to calibrate the compass again. If the calibration continues to fail, contact an authorized Suunto service center.
5. BEFORE DIVING Do not attempt to use the dive computer without reading this user's 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 Suunto D9, please contact your Suunto representative before diving with the dive computer.
5.1. The Suunto RGBM/Deep Stop Algorithm Suunto’s Reduced Gradient Bubble Model (RGBM), utilized in the Suunto D9 , predicts both dissolved and free gas in the 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. The Suunto D9 allows you to choose between a traditional Recommended Safety Stop and Deep Stops.
5.3. Dive computer limitations While the dive computer's calculations are based on current decompression research and technology, it is important to realize that the computer cannot monitor the actual physiological functions of an individual diver. All decompression schedules currently known to the authors, including the U.S. Navy Tables, are based on theoretical mathematical models, which are intended to serve as a guide to reduce the probability of decompression illness. 5.4.
Anyone who engages in any form of breathhold diving is in danger of shallow-water blackout (SWB), that is, the sudden loss of consciousness caused by oxygen starvation. Any breathhold diving results in some nitrogen build-up in the blood and other fast tissues. Due to the short time spent at depth, this build-up is generally not significant. Therefore, provided the effort involved in freediving has not been severe, there is little risk in diving after breathhold diving.
Table 5.1. Audible and visual alarm types Alarm type Short single beep Alarm reason Dive computer is activated. Dive computer automatically returns to the TIME mode. Three beeps with a three second interval Cylinder pressure reaches 50 bar/725 psi. The cylinder pressure display will start to blink. Cylinder pressure reaches the selected alarm pressure. Calculated remaining air time reaches zero.
You are able to preset alarms before the dive. The programmable alarms can be set for maximum depth, dive time and time. See also Section 5.9. DIVE mode settings and Section 4.1. TIME mode settings. Table 5.2. Preset alarm types Alarm type Alarm reason Continuous beep series for 24 seconds Maximum depth blinks as long as the current depth value exceeds the preset value. Preset maximum depth is reached. Continuous beep series for 24 seconds or until any button is pressed. Dive time blinks for one minute.
Table 5.3. Oxygen alarms in NITROX mode Alarm type Continuous beeps for 3 minutes and activated backlight Alarm reason Set oxygen partial pressure limit is exceeded. The alternative display is replaced with a current blinking PO2 value. You should immediately ascend above the PO2 depth limit. OLF value reaches 80%. The OLF value will start to blink. OLF value reaches 100%. The OLF value will blink. NOTE When the backlight is turned OFF, it does not illuminate when an alarm is activated.
5.7. Error conditions The dive computer has warning indicators that alert you to react to certain situations that would significantly increase 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 understand the dive computer and operate it 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.
5.8. Wireless transmission The D9 can be used together with an optional wireless cylinder pressure transmitter that easily attaches to the high-pressure port of the regulator. By using the transmitter, you can benefit from receiving cylinder pressure and remaining air time data direct to your wrist. In order to use the transmitter, the wireless integration needs to be enabled in your Suunto D9’s settings. To enable or disable the wireless integration refer to Section 5.9.8. Tank pressure. 5.8.1.
5.8.2. Pairing and code selection In order to receive wireless data, the transmitter and the Suunto D9 need to be paired. During the pairing procedure, the transmitter and dive computer select a common transmission code. The transmitter is activated when the pressure exceeds 15bar/218 psi and it then starts sending pressure data together with a code number. During the pairing procedure, the Suunto D9 stores the code number and starts displaying pressure values that are received with that code.
4. Take the Suunto D9 wrist unit close to the transmitter. The unit will then quickly display the selected code number and then start displaying the transmitted cylinder pressure. A lightning symbol is displayed every time the Suunto D9 receives a valid signal. WARNING If there are several divers using Suunto D9s with wireless transmission, always ensure that each diver is using a different code before starting the dive.
5.8.3. Transmitting data After the pairing procedure, the Suunto D9 will receive cylinder pressure data from the transmitter. The pressure is displayed in either bars or psi, depending on the unit selected. Any time the Suunto D9 receives an appropriate signal it flashes the lightning figure in the display’s lower left corner. A pressure reading of over 360 bar/5220 psi will display as “---“.
Display Indication Figure LOB Indicates pressure transmitter battery voltage is low. Change the transmitter battery! D OFF Pairing has not been conducted before start of dive. No cylinder data available. E A B C D E 5.9. DIVE mode settings Suunto D9 has several user-definable functions, as well as depth and time-related alarms that you can set according to your personal preferences.

The depth alarm is factory-set to 40 m/131 ft, but you can adjust it according to your personal preference, or switch it off altogether. The depth range can be set from 3m to 100 m/9 ft to 328 ft. 5.9.2. Setting the dive-time alarm The Suunto D9 has a dive-time alarm setting which, when activated, can be used for several purposes to add to your diving safety. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON.
In order to minimize the risk of error during a dive, it is highly recommended that the mixes are set in the proper order. This means that as the mix number rises, so does oxygen content, and this is the order they are usually used during the dive. Before a dive, only set to “ON” the mixes you actually have available and remember to check the set values to make sure they are correct. The default oxygen percentage (O2%) setting is 21% (air) and oxygen partial pressure (PO2) setting 1.4 bar.
5.9.4. Setting the personal/altitude adjustments The current Altitude and Personal Adjustment settings are displayed in the startup screen when entering the DIVE mode. If the mode does not match the altitude or personal conditions (see Section 5.10.4. Diving at altitude and Section 5.10.5. Personal adjustments), it is imperative that you enter the correct selection before diving. Use Altitude Adjustment to select the correct altitude and use Personal Adjustment to add an extra level of conservatism.
5.9.6. Setting the Safety Stops/Deep Stops The Deep Stop setting allows you to choose between traditional Safety Stops or Deep Stops. If Deep Stops are set to OFF, the traditional Safety Stop calculation is used. If set to ON, iterative Deep Stops will be prompted instead. The length of the individual Deep Stops can be set to 1 or 2 minutes. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.9.7.
5.9.8. Tank pressure The wireless transmission can be set “ON” or “OFF” depending whether the optional wireless pressure transmitter is used or not. No cylinder pressure-related data is shown, nor data reception made, when this selection is “OFF”. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. You can set the secondary cylinder pressure alarm point. The 50 bar alarm is fixed and cannot be changed, but the secondary alarm pressure can be set in the range 10 –200bar. 5.9.9.
5.9.10. HP code The HP Code setting allows you to verify the selected code and to erase the stored code. It also enables re-pairing if necessary. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.10. Activation and pre-checks This section describes how to activate the DIVE mode and explains the pre-checks that it is highly recommended you perform before you get into the water. 5.10.1.
5.10.2. DIVE mode activation The dive computer activates automatically when submerged deeper than 0.5 m/1.5 ft. However, it is necessary to activate the DIVE mode BEFORE diving to check the cylinder pressure, altitude and personal adjustment settings, battery condition, oxygen settings etc. After activation, all display elements turn on showing mostly figure 8s and graphical elements, and the backlight and the beep are activated.
the instrument operates in the correct mode and provides a complete display (AIR/NITROX/GAUGE mode) • the battery level is ok • the altitude, personal adjustment, Safety/Deep stops, and RGBM settings are correct • the instrument displays correct units of measurement (Metric/Imperial) • the instrument displays the correct temperature and depth (0.
5.10.3. Battery power indication Temperature or internal oxidation of the battery affect the battery voltage. If the instrument is stored for a long period, or used in cold temperatures, the low battery warning may be displayed even though the battery has enough capacity. In these cases, re-enter DIVE mode to receive the battery power indication. After the battery check, the Low Battery Warning is indicated by the battery symbol.
5.10.4. Diving at altitude The dive computer can be adjusted both for diving at altitude and also to increase the conservatism of the mathematical nitrogen model. When programming the instrument for the correct altitude, you need to select the correct Altitude Adjustment settings according to Table 5.6, Altitude Adjustment settings. The dive computer will adjust its mathematical model according to the entered altitude setting, giving shorter no-decompression times at higher altitudes (see Table 9.
5.10.5. Personal adjustments There are personal factors that can affect your susceptibility to DCI, which you can predict in advance, and input into the decompression model. Such factors vary between divers and also for the same diver from one day to another. The three-step Personal Adjustment setting is available if a more conservative dive plan is desired and, for very experienced divers, a two step adjustment for RGBM effect on repetitive dives is available.
Table 5.7. Personal Adjustment settings Personal Condition adjustment value Desired tables P0 Ideal conditions Default P1 Some risk factors or conditions exist Progressively more conservative P2 Several risk factors or conditions exist The Suunto D9 also allows experienced divers who are willing to accept a greater level of risk to adjust the RGBM model. The default setting is 100%, which gives full RGBM effect. Suunto strongly advises you to use full RGBM effect.
RGBM setting Desired Tables Effect 50% Attenuated RGBM model Smaller RGBM effects, higher risk! 5.11. Safety Stops Safety Stops are widely considered good diving practice for recreational diving, and are an integral part of most dive tables. The reasons for performing a Safety Stop include: reducing sub-clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. The Suunto D9 displays two different types of Safety Stops: Recommended Safety Stop and Mandatory Safety Stop. 5.
WHEN STOP IS DISPLAYED, MAKE A RECOMMENDED SAFETY STOP FOR 3 MINUTES. NOTE 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. 5.11.2. Mandatory Safety Stops When the ascent rate exceeds 10 m/33 ft per minute continuously for more than 5 seconds, the microbubble build-up is predicted to be more than is allowed for in the decompression model.
WHEN CEILING AND STOP ARE DISPLAYED, MAKE A ONE MINUTE MANDATORY SAFETY STOP IN THE DEPTH ZONE BETWEEN 6 M AND 3 M. 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. You should immediately descend to, or below, the Mandatory Safety Stop ceiling depth.
5.12. Deep stops The Suunto D9 allows you to choose a Deep Stop algorithm instead of the traditional Recommended Safety Stop. Deep Stops are safety stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation and excitation. The Suunto RGBM model calculates deep stops iteratively, placing the first stop about halfway between the maximum depth and the ceiling depth.
6. DIVING This section contains instructions on how to operate the dive computer and interpret its displays. You’ll find that this dive computer is easy to use and read. Each display shows only the data relevant to that specific diving mode. 6.1. Diving in AIR mode (DIVEair) In this section, we look at how to make the most of the dive computer when diving with standard air. To activate DIVEair mode, please see Section 5.10.1. Accessing DIVE mode.
• • • • your present depth in meters/feet the available no-decompression time in minutes as NO DEC TIME the ascent rate presented as a bar graph on the right side the Diver Attention Symbol if surface interval should be prolonged (see Table 7.1, Alarms) DIVE DISPLAY - PRESENT DEPTH IS 15 M, NO-DECOMPRESSION STOP TIME LIMIT IS 61 MIN. MAXIMUM DEPTH DURING THIS DIVE WAS 21. 5 M, ELAPSED DIVE TIME IS 5 MIN.
UP BUTTON TOGGLES BETWEEN DIVE TIME AND WATER TEMPERATURE. In addition, with the optional wireless transmission enabled: • the Remaining Air-time in the left center window indicated as AIR TIME • the cylinder pressure in bar (or psi) displayed in the lower left corner • the cylinder pressure graphically displayed on the left side 6.1.2. Bookmark It is possible to record bookmarks in the profile memory during a dive. These bookmarks are displayed when scrolling the profile memory on the display.
6.1.3. Tank pressure data When using the optional wireless pressure transmitter, the pressure of your scuba cylinder in bars (or psi) is shown digitally in the lower left corner of the alternative display. Whenever you start a dive, the remaining air time calculation begins. After 30 - 60 seconds (sometimes more, depending on your air consumption), the first estimation of remaining air time will be shown in the left center window of the display.
NOTE Filling your BC affects the air time calculation due to the temporary increase in air consumption. NOTE A change of temperature will affect the cylinder pressure and consequently the air time calculation. Low Air Pressure Warnings The dive computer will warn you with three audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar/725 psi. TANK PRESSURE HAS DROPPED BELOW 50 BAR AND THE REMAINING AIR TIME IS 4 MINUTES.
NORMAL ASCENT RATE. WARNING ACTIVATED BACKLIGHT, ALARM AND A BLINKING ASCENT RATE BAR GRAPH INDICATE YOU ARE ASCENDING FASTER THAN 10 M/MIN. YOU ARE ADVISED TO MAKE A MANDATORY SAFETY STOP WHEN YOU REACH A DEPTH OF 6 M. DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents increase the risk of injury. You should always make the Mandatory and Recommended Safety Stops after you have exceeded the maximum recommended ascent rate.
YOU ARE ADVISED TO MAKE A DEEPSTOP AT 12 M. THE SECOND INDICATOR SHOWS THAT YOU HAVE 58 SECONDS LEFT OF YOUR DEEPSTOP. 6.1.6. Decompression dives When your NO DEC TIME becomes zero, your dive becomes a decompression dive so you must perform one or more decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by an ASC TIME, and a CEILING notation will appear. An upward pointing arrow will also prompt you to start your ascent.
• the time needed to reach the surface after the ceiling and Safety Stops have been completed WARNING YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DISPLAYED BY THE INSTRUMENT! The ascent time will increase if you: • remain at depth • ascend slower than 10 m/33 ft per minute • make your decompression stop deeper than at the ceiling These factors will also increase the amount of air required to reach the surface.
The depth of the ceiling and floor will depend on your dive profile. The ceiling depth will be fairly shallow when you enter the decompression mode, but if you remain at depth, it will move downward and the ascent time will increase. Likewise, the floor and ceiling may change upwards while you are decompressing. When conditions are rough, it may be difficult to maintain a constant depth near the surface.
Display below the floor The blinking ASC TIME and an upward pointing arrow indicate that you are below the floor. You should start your ascent immediately. The ceiling depth is shown on the left side, and the minimum total ascent time on the right side, of the center window. Below is an example of a decompression dive without Deep Stops, below the floor. UPWARD POINTING ARROW, BLINKING ASC TIME AND AN ALARM TELL YOU TO ASCEND. MINIMUM TOTAL ASCENT TIME INCLUDING SAFETY STOP IS 4 MINUTES. CEILING IS AT 3 M.
Display at the ceiling zone When you reach the ceiling zone, the display will show you two arrows pointing at each other (the “hour glass” icon). Below is an example of a decompression dive at the ceiling zone. TWO ARROWS POINT AT EACH OTHER “HOUR GLASS”. YOU ARE IN THE OPTIMUM CEILING ZONE AT 3 M. AND YOUR MINIMUM ASCENT TIME IS 8 MINUTES. During the decompression stop, ASC TIME will count down towards zero. When the ceiling moves upwards, you can ascend to the new ceiling.
DECOMPRESSION DIVE, ABOVE CEILING. NOTE DOWNWARD POINTING ARROW, ER WARNING AND ALARM. YOU SHOULD IMMEDIATLY (WITHIN 3 MINUTES) DES CEND TO OR BELOW CEILING. In addition, an Error warning (Er) reminds you that you have only three minutes to correct the situation. You must immediately descend to, or below, the ceiling. If you continue to violate the decompression, the dive computer will go into a permanent Error Mode. In this mode, the instrument can only be used as a depth gauge and timer.
to be understated and will affect decompression calculations. If you want 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 according to the entered O2% and PO2 values. Calculations based on nitrox use result in longer no-decompression times and shallower maximum depths than diving with air.
6.2.2. Oxygen displays When NITROX mode is activated, the display will show the information in the figure below. In NITROX mode, the maximum operational depth is calculated based on set O2% and PO2 values. NITROX DIVE MODE ACTIVATION. MAXIMUM OPERATIONAL DEPTH BASED ON SET O2% (21%) AND PO2 (1.4 BAR) IS 56.7 M.
DOWN BUTTON TOGGLES BETWEEN O2, MAXIMUM DEPTH AND CURRENT TIME. UP BUTTON TOGGLES BETWEEN PO2, OLF, DIVE TIME AND WATER TEMPERATURE. 6.2.3. Oxygen limit fraction (OLF) If set to NITROX mode, 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 Oxygen Limit Fraction (OLF) displays only the value of the higher of the two calculations. The oxygen toxicity calculations are based on the factors listed in Section 9.3 “Oxygen exposure”. 6.2.4. Gas change and multiple breathing gas mixes The Suunto D9 allows gas changes to enabled gas mixes during the dive. Gas changes are made by following the procedure below: CHANGING GAS MIX. SCROLL THROUGH ENABLED MIXES BY PRESSING THE UP OR DOWN BUTTONS. SELECT NEW MIX BY PRESSING THE SELECT BUTTON.
6.3. Diving in GAUGE mode (DIVEgauge) If set to GAUGE mode, the dive computer can be used as a bottom timer or as a freediving instrument. In the GAUGE mode, the total dive time is always displayed in minutes in the lower right corner. In addition, a Dive Timer in the center window displays time in minutes and seconds. The center window Dive Timer is activated at the start of the dive and it can be reset during the dive and used as a stopwatch by pressing the SELECT button.
7. AFTER DIVING 7.1. At the surface Once back at the surface, Suunto D9 continues to provide post-dive safety information and alarms. Calculations to enable repetitive dive planning also help to maximize diver safety. 7.1.1. Surface interval An ascent to any depth shallower than 1.2 m/4 ft will cause the DIVING display to be replaced by the SURFACE display: IT IS 6 MINUTES SINCE YOU SURFACED FROM A 35-MINUTE DIVE. THE MAXIMUM DEPTH WAS 21.5 M. THE PRESENT DEPTH IS 0.0 M.
• • the oxygen partial pressure labeled PO2 the current oxygen toxicity exposure labeled OLF 7.1.2. Dive numbering Several repetitive dives are considered to belong to the same repetitive dive series when the dive computer has not counted the no-fly time to zero. Within each series, the dives are given individual numbers. The first dive of the series will be numbered as DIVE 1, the second as DIVE 2, the third as DIVE 3, etc.
7.1.3. Repetitive dive planning The Suunto D9 includes a dive planner that allows you to review the no-decompression limits on a subsequent dive, taking the residual nitrogen loading of previous dives into consideration. The Dive Planning mode is explained in Section Dive Planning mode (MEMplan) in Section 7.1.5. MEMORY mode . 7.1.4. Flying after diving The no-fly time is shown in the center window next to the airplane image.
If a diver has less than 2 hours total accumulated dive time in the last 48 hours, 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, as well as the dive computer’s no-fly conditions, are satisfied • • 7.1.5.
When entering the MEMplan mode, the display first briefly shows the remaining desaturation time before going into plan mode. By pressing the UP/DOWN buttons, you can scroll the no-decompression limits in 3 m/10 ft increments ending at 45 m/150 ft. No-decompression limits longer than 99min are displayed as “—“. WHEN ENTERING THE MEMPLAN MODE THE DISPLAY FIRST BRIEFLY SHOWS THE REMAINING DESATURATION TIME BEFORE GOING INTO PLAN MODE. USE UP AND DOWN BUTTONS TO SCROLL DIFFERENT NO-DECOMPRESSION LIMITS.
NOTE The Planning mode is disabled in GAUGE mode and in Error mode (see Section 5.7. Error conditions). The planning mode calculates no-decompression times for MIX1 only. If additional mixes are enabled in the NITROX mode, they do not affect the calculations in MEMplan mode. Higher Altitude and conservative Personal Adjustment settings will shorten the nodecompression time limits. These limits at different Altitude and Personal Adjustment setting selections are explained in Section 5.10.4.
The END OF LOGS text is displayed between the oldest and most recent dive. The following information will be shown on three pages: THERE ARE THREE PAGES OF LOGBOOK DIVE INFORMATION. USE SELECT BUTTON TO SCROLL BETWEEN LOGBOOK PAGES I, II, AND III. THE DATA OF THE MOST RECENT DIVE IS SHOWN FIRST. Page I, main display • Maximum depth (NOTE! Depending on the sampling rate, the reading may differ from the maximum depth reading of the Dive History up to 0.3 m/1 ft.
• warnings • used tank pressure (if enabled) Page III • depth/time profile of the dive • real-time water temperature • real-time tank pressure (if enabled) The memory will retain approximately the last 36 hours of dive time. After that, when new dives are added, the oldest dives are deleted. The contents of the memory will remain when the battery is changed (providing that the battery has been replaced according to the instructions).
The Dive History Memory can hold a maximum of 999 dives and 999 diving hours. When these maximum values are reached, the counters will start again from zero.

NOTE Low temperature or an internal oxidation of the battery may activate the battery warning even though the battery has enough capacity. In this case, the warning usually disappears when the DIVE mode is activated again. 9.2. 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 co-operation between Suunto and Bruce R. Wienke BSc, MSc, PhD.
9.2.1. 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 also changes these calculations according to the personal adjustment you select. The pattern and speed of decompression at the surface is adjusted according to microbubble influence. On repetitive dives, adjustment may also be applied to the maximum allowable nitrogen overpressure in each theoretical tissue group.
9.2.2. No-decompression limits The no-decompression limits displayed by the dive computer for the first dive to a single depth (see Table 9.1, No-decompression time limits for various depths (m) and Table 9.2, No-decompression time limits for various depths (ft) .), are slightly more conservative than those permitted by the U.S. Navy tables. Table 9.1.

Altitude diving The atmospheric pressure is lower at high altitudes than at sea level.
As a result, the allowed no-decompression-stop limits are considerably reduced. 9.3. Oxygen exposure The oxygen exposure calculations are based on currently accepted exposure time limit tables and principles. In addition to this, the dive computer uses several methods to conservatively estimate the oxygen exposure. For example: • the displayed oxygen exposure calculations are raised to the next higher percentage value • for recreational scuba diving, the recommended upper limit of 1.

GLOSSARY Air time The amount of dive time remaining, based on a calculation of cylinder pressure and ambient pressure and present air consumption. Altitude dive A dive made at an elevation greater than 300 m/1000 ft above sea level. 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.
Decompression Time spent at a decompression stop, or range, before surfacing, to allow absorbed nitrogen to escape naturally from tissues Decompression range On a decompression stop dive, the depth range between the floor and the ceiling within which a diver must stop for some time during ascent.
Half time After a change in ambient pressure, the amount of time required for the partial pressure of nitrogen in a theoretical compartment to go half way from its previous value to saturation at the new ambient pressure. HP Abbreviation for high pressure (= cylinder pressure). Multi level dive A single or repetitive dive that includes time spent at various depths and whose no decompression limits are therefore not determined solely by the maximum depth attained.
O2% Oxygen percentage or oxygen fraction in the breathing gas. Standard air has 21% oxygen. Oxygen partial pressure Limits the maximum depth to which the nitrox mixture can be safely 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 risk immediate oxygen toxicity.
