• Page 18: Getting Started With Your Suunto D4

  BEFORE getting into the water. 4.1. TIME mode settings The first thing you’ll want to do with your Suunto D4, is to set the alarm, time, dual time, date, units, backlight, and tones. In this section, we look at how to do this.

• Page 19: Setting The Alarm

  The display is illuminated by holding down the MODE button for NOTE more than 5 seconds. Now that you know how to toggle between the shortcuts, you can start to set them. The following figure shows how to enter the TIME SETTINGS menu. 4.1.1.

• Page 20: Setting The Time

  ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 4.1.2. Setting the time In the TIME SETTING mode, you are able to set the hour, minute, and second, as well as choose between 12 and 24 hour display. ADJUST WITH UP AND DOWN BUTTONS.

• Page 21: Setting The Date

  4.1.4. Setting the date Use the DATE SETTING mode to set the year, month, and day. The day of the week is automatically calculated in accordance with the date. 4.1.5. Setting the units In the UNITS SETTING mode you can choose to have the units displayed in either the metric or imperial system — meters/feet, Celsius/Fahrenheit etc.

• Page 22: Setting The Backlight

  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. 4.1.7.

• Page 23: Stopwatch

  When the tones are off, there are no audible alarms. NOTE 4.2. Stopwatch The Suunto D4’s stopwatch measures elapsed and split times. 4.3. AC water contacts The water and data transfer contact is located on the side of the case. When sub- merged, the water contact poles are connected by the conductivity of the water and the “AC”…

• Page 24
  Contamination or dirt on the water contact may prevent this automatic activation. It is therefore important that the water contact is kept clean. The contact can be cleaned with fresh water and a soft brush, for example a tooth brush.

• Page 25: Before Diving

  Always remember that YOU ARE RESPONSIBLE FOR YOUR OWN SAFETY! When used properly, Suunto D4 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 decompres- sion.

• Page 26: The Suunto Rgbm/Deep Stop Algorithm

  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.

• Page 27: Dive Computer Limitations

  Stay there for as long as your air supply will safely allow. After reaching the sur- face, do not dive for at least 24 hours. 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.

• Page 28: Free Diving

  DIVING IS NOT RECOMMENDED. You should avoid Free diving, and not exceed 5 m/16 ft, for at least two hours after scuba diving. Suunto also recommends that you receive training in Free diving WARNING techniques and physiology before conducting breath hold dives.

• Page 29
  Table 5.1. Audible and visual alarm types Alarm type Short single beep Three beeps with a three second interval and activated backlight Continuous beeps and activ- ated backlight You are able to preset alarms before the dive for maximum depth, dive time and time. See also Section 5.8.
• Page 30
  Table 5.2. Preset alarm types Alarm type Continuous beep series for 24 seconds Maximum depth blinks as long as the current depth value exceeds the preset value. Continuous beep series for 24 seconds or until any button is pressed. Dive time blinks for one minute. Continuous beep series for 24 seconds or until any button is pressed.

• Page 31: Error Conditions

  When the backlight is turned OFF, it does not illuminate when an NOTE alarm is activated. WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE WARNING MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY TAKE ACTION TO REDUCE OXYGEN EXPOSURE. Failure to take action to reduce oxygen exposure after the warning is given can rapidly increase the risk of oxygen toxicity, injury, or death.

• Page 32: Dive Mode Settings

  5.8. DIVE mode settings Suunto D4 has several user-definable functions, as well as depth and time-related alarms that you can set according to your personal preferences. The DIVE mode settings are dependent on the dive submode chosen (AIR, NITROX, FREE), so that, for example, nitrox settings are only available in the NITROX submode.

  Some settings cannot be changed until 5 minutes has elapsed NOTE after the dive. 5.8.1. Setting the depth alarm You can set a depth alarm in the dive computer. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. USE UP AND DOWN BUTTONS TO TOGGLE BETWEEN DIVE SETTINGS.

• Page 35: Setting The Depth Notify Alarm (Free Mode)

  5.8.3. Setting the dive-time alarm The Suunto D4 has a dive-time alarm setting which, when activated, can be used for several purposes to add to your diving safety. With a range of 1 — 999 minutes, the alarm can be set to your NOTE planned bottom time, for example.

• Page 36: Setting The Nitrox Values

  5.8.4. Setting the nitrox values If set to the NITROX 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. In addition, the oxygen partial pressure limit must be set. When in the NITROX setting mode, the equivalent allowed maximum depth, based on the chosen setting, will also be displayed.

• Page 37: Setting The Surface Time Notify Alarm (Free Mode)

  5.8.6. Setting the surface time notify alarm (FREE mode) You can set a surface time notify alarm to indicate the length of the surface time before a new dive. Suunto D4 starts counting the time automatically when you surface (at 0,5 m/1,6 ft).

• Page 38: Setting The Deep Stops

  5.8.8. Setting the Deep Stops If set to ON, iterative Deep Stops will be prompted. The length of the individual Deep Stops can be set to 1 or 2 minutes. 5.8.9. Setting the RGBM values For certain divers and diving conditions, it may be desirable to set the attenuated RGBM mode.

• Page 39: Accessing Dive Mode

  5.9.1. Accessing DIVE mode The Suunto D4 has three diving modes: AIR mode for diving with standard air only, NITROX mode for diving with oxygen enriched mixtures, and FREE mode for free diving. The OFF mode disables the DIVE mode, and allows the TIME mode to be used un- derwater.

• Page 40
  At this time, perform your pre-checks, making sure that: the instrument operates in the correct mode and provides a complete display • (AIR/NITROX/FREE mode) the battery level is ok • the altitude, personal adjustment, Safety/Deep stops, and RGBM settings are •…

• Page 41: Battery Power Indication

  5.9.3. Battery power indication Temperature or internal oxidation of the battery affect the battery voltage. If the instru- ment 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.

• Page 42
  When programming the instrument for the correct altitude, you need to select the correct Altitude Adjustment settings according to Table 5.5, 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 10.1, No-decompression time limits for various depths (m) and Table 10.2, No-decompression time limits for various depths (ft) in Section 10.2.

• Page 43: Personal Adjustments

  5.9.5. 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.

• Page 44
  Several risk factors or conditions exist The Suunto D4 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. Statistically, very experienced divers have less incidents with DCI.

• Page 45: Safety Stops

  The reasons for performing a Safety Stop in- clude: reducing sub-clinical DCI, microbubble reduction, ascent control, and orientation before surfacing. The Suunto D4 displays two different types of Safety Stops: Recommended Safety Stop and Mandatory Safety Stop. 5.10.1. Recommended Safety Stops With every dive over 10 meters, there is a three minute countdown for the Recommen- ded Safety Stop, to be taken in the 6 — 3 m/10 ft — 20 ft range.

• Page 46: Mandatory Safety Stops

  The Suunto RGBM calculation model responds to this by adding a Mandatory Safety Stop to the dive. The time of this Mandatory Safety Stop depends on the severity of the ascent rate excess.

• Page 47
  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.

• Page 48: Deep Stops

  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. After the first Deep Stop is completed, another Deep Stop will be prompted halfway to the ceiling, and so on until the ceiling depth is reached.

• Page 51: 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. The bookmarks will also be shown as annotations in the downloadable Suunto Dive Manager PC software. The bookmark logs the depth, time and water temperature.

• Page 52: Decompression Dives

  6.1.4. 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.

• Page 53
  YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DIS- WARNING PLAYED 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.
• Page 54
  In such cases, it is more manageable to maintain an additional distance below the ceiling, to make sure that the waves do not lift you above the ceiling. Suunto re- commends that decompression takes place deeper than 4 m/13 ft, even if the indicated ceiling is shallower.
• Page 55
  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.
• Page 56
  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”…

• Page 57: Diving In Nitrox Mode (Divenitrox)

  You must not dive again for at least 48 hours. (See Section 5.7. Error conditions). 6.2. Diving in NITROX mode (DIVEnitrox) NITROX mode (DIVEnitrox) is the second dive mode available in Suunto D4 and is used when using oxygen- enriched gas mixtures.

• Page 58: Oxygen Displays

  To set the nitrox mixes, refer to Section 5.8.4. Setting the nitrox values. Default nitrox settings In NITROX mode, the Suunto D4 allows you to set a nitrox mix containing 21-50% oxygen. In the NITROX mode, the default setting is standard air (21% O ).

• Page 59: Maximum Depth

  MAXIMUM OPERATIONAL DEPTH BASED ON SET O If set to NITROX mode, the Suunto D4 will additionally show on the alternative display: • the oxygen percentage, labeled O the set oxygen partial pressure limit, labeled PO • • the current oxygen toxicity exposure, labeled OLF maximum depth •…

• Page 60: Oxygen Limit Fraction (Olf)

  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 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).

• Page 61: Day History

  The free dive ends as soon as you surface (at 0,5 m/ 1,6 ft). The FREE mode does not provide decompression information. NOTE There is no ascent rate monitoring in the FREE mode. NOTE 6.3.1. Day History The Day History shows the free dive history of your latest diving day. In the Surface mode you can enter the Day History by pressing the SELECT button.

• Page 62
  The Day History shows the average depth of all dives, the deepest depth of the day as well as the time, the longest dive, and the cumulative dive time in hours and minutes, as well as the number of dives made during the day. The first dive of the next day will reset the Day History and start NOTE a new one.

• Page 63: Free Dive Time Limit

  6.3.2. Free dive time limit The FREE mode has a time limit of 10 minutes. After 10 minutes, Suunto D4 will automatically change from free dive to scuba bottom timer. After the dive, the no-fly time will countdown from 48 hours. Also, you will not be able to dive in AIR or NITROX modes until the no-fly time has counted down to zero.

• Page 64: After Diving

  7. AFTER DIVING Once back at the surface, Suunto D4 continues to provide post-dive safety information and alarms. Calculations to enable repetitive dive planning also help to maximize diver safety.

• Page 66: Free Dive

  7.3. Repetitive dive planning The Suunto D4 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.

• Page 67: Memory Mode

  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 7.5.
