1 Terminology / Symbols

1.3 Nitrox information (O2 information) For dives with compressed air in normal recreational diving, nitrogen is the decisive gas for the decompression calculations. When diving with Nitrox, the risk of oxygen toxicity rises with the increase of the fraction of oxygen and the increase of depth and can limit dive time and the maximum depth. Smart includes this in the calculations and displays the necessary information: <O2% MIX> Fraction of oxygen: the fraction of oxygen in the Nitrox mixture can be set between 21% (normal compressed air) and 100% in 1% increments. Your selected mix will be the basis for all calculations. Maximum allowed partial pressure of oxygen: the higher the fraction of oxygen in the mixture, the shallower the dive depth at which this value of the partial pressure of oxygen is reached. The depth at which ppO2 max. is reached is called Maximum Operating Depth (MOD). Default setting is 1.4 bar, but it can be set by means of SmartTRAK between 1.0 and 1.95 bar. Smart does not display the entered ppO2 limit, but warns the diver audibly and visually once the depth is reached at which the ppO2 reaches the maximum allowed value. The CNS O2% value/alarm is not influenced by the selected ppO2max. setting. <CNS O2> Oxygen toxicity: With the increased percentage of oxygen, the oxygen in the tissues (especially in the central nervous system (CNS)) becomes important. If the partial pressure of oxygen rises above 0.5 bar, the CNS O2 value increases, if the partial pressure of oxygen is below 0.5 bar, the CNS O2 value decreases. The closer the CNS O2 value is to 100%, the closer the limit where symptoms can occur -> 17.

ppO2 0,21 bar

Nitrox diving may only be attempted by experienced divers after proper training from an internationally recognized agency.
2 Attention messages and alarms
Smart draws the divers attention to certain situations and warns the diver of unsafe diving practices. Attention messages and alarms are always visual and audible under water, only visual at the surface except the decompression alarm. The audible attention messages (but not the alarms) can be switched off selectively with SmartTRAK. 2.2 Alarms Serious injury or death may result from failing to immediately respond to alarms given by Smart. Alarms are given to the diver visually by flashing symbols, letters or figures. In addition, an audible sequence in one frequency can be heard during the whole duration of the alarm. (can not be switched off) An alarm occurs in the following situations (more information can be found on the listed pages): Page 25 Low battery alarm** The service symbol appears if the battery capacity reaches 0%. Take the unit to your authorised SCUBAPRO % UWATEC retailer.

2.1 Attention messages Attention messages are communicated to the diver visually by symbols, letters or flashing figures. In addition, two short audible sequences can be heard (in an interval of 4 seconds) in two different frequencies under water. 4 sec (can be switched off)
Attention messages come up in the following situations (more information can be found on the listed pages): Page Maximum Operating Depth / max. ppO2 is reached Set maximum depth is reached Oxygen toxicity reaches 75% No-stop time = 2 minutes Prohibited altitude* (surface mode) Entering decompression when diving with L0 COM Remaining Bottom Time <3 minutes COM Tank pressure has reached set warning level COM Increased workload Diving with microbubble levels (L1-L5): MB no-stop time = 0 MB level stop ignored MB level reduced Entering decompression when diving DEPTH with MB level L1-L5
Oxygen toxicity reaches 100% Ignored decompression COM Remaining Bottom Time = 0 Exceeding the prescribed ascent rate (Particular scale of beeps, ->16)

3 Preparation for the dive
3.1 Setting the gas mixture Before every dive and after changing the tank, make sure that the setting of the gas mixture corresponds to the current mixture used. An incorrect setting causes Smart to miscalculate this particular dive. If the fraction of oxygen is set too low this can lead to oxygen poisoning without warning. If the value is set too high decompression sickness may occur. Inaccuracies in the calculations are carried over to repetitive dives. To set the gas mixture, Smart must be in user mode.
1. Bridge contacts B and + or B and until the symbol for the setting of the O2 mixture appears. 2. Confirm that you wish to change the displayed oxygen fraction by bridging B and E.

DEPTH MAX.DEPTH

DIVE TIME DECO INFO
3. Change the oxygen fraction in increments of 1% by bridging contacts B and + to increase or B and to decrease (21-100%). 4. Confirm the selected percentage with B and E.
Without confirmation the display will disappear after 3 minutes and your entries will not be accepted. The time to reset the O2 % mix to air can be set with SmartTRAK between 1 and 48 hours or to "no reset" (default).

4.7 Oxygen toxicity (CNS O2%) % Smart calculates oxygen toxicity from depth values, time and the gas mixture and displays it in the location of the ascent rate. The toxicity is expressed in 1% increments of a maximum tolerated value (O2 clock). The symbol <CNS O2> is % displayed together with the percentage.

Oxygen toxicity 4 sec

An audible attention signal goes off if oxygen toxicity reaches 75%. The symbol <CNS O2> flashes and the ascent arrow appears. Ascend to shallower depth to decrease oxygen loading.
When oxygen toxicity reaches 100%, an audible alarm goes off every 4 seconds. <CNS O2>, the precentage value and the ascent arrow flash. Danger of oxygen toxicity! Start ascent at once.
During an ascent and if the CNS O2% value does not increase anymore (due to a lower partial pressure of oxygen), the audible warning is suppressed. During the ascent, the display of the oxygen toxicity is replaced by the ascent rate. If the ascent is stopped, the display changes back to the indication of the CNS value. 4.8 COM Tank pressure
Tank pressure is indicated in the lower display. The tank pressure is also used for the calculation of the remaining bottom time (RBT) and the workload.
When the tank pressure reaches the set warning pressure (SmartTRAK) an audible alarm goes off and the tank symbol is shown. Default value of the warning pressure: 100 bar (1450 psi). Do not dive any deeper. Start to ascend soon. In case of increased workload, Smart COM displays a lung symbol in the lower display and an audible attention message occurs. In order to prevent additional saturation, reduce exertion, relax and breathe more slowly.
TANK Remaining Bottom Time (RBT) 4.9 COM DATA RBT is the time left at the current depth until the point of time when the ascent must bar be started. The RBT is shown in the lower display. The RBT is calculated on the basis of the current tank pressure, breathing rate, the temperature, and the dive data RBT so far recorded. The RBT is based on the assumption that the tank pressure should amount to the set pressure (default 40 bar/600 psi) at the end of the dive. Alterations can be made with SmartTRAK. A graphic representation of RBT is on page 11.
Never allow the RBT to go below three minutes. If the RBT goes below three minutes there is a danger of insufficient supply of gas mixture for the ascent as well as an increased risk of decompression sickness, and serious injury or death may result! Correct calculation of RBT when using a reserve or J type valve is possible only if the reserve function of the valve is in the open (down) position during the dive.
If the RBT drops below three minutes, an audible attention signal is activated, the ascent arrow is displayed and the tank icon and RBT start flashing. Start ascent immediately.

If the total (cumulative) duration of the decompression alarm is longer than one minute, it is entered in the logbook. Descend to the prescribed decompression stop depth immediately!

Total time of ascent

As soon as decompression stops are necessary Smart shows the total time of ascent. This includes the ascent time from the current depth to the surface and all decompression stop obligations. The total time of ascent is calculated on the basis of the prescribed ascent rate and a normal workload. Total time of ascent can be subject to change if the ascent rate is not ideal (100%) or if Smart COM detects a higher workload.
On all dives with Smart, make a safety stop for at least three minutes at a depth of 5 m (15 feet).
On entering the decompression phase, the arrow NO STOP disappears, the arrow DECOSTOP appears and an attention beep goes off. Right beside the arrow, the deepest decompression stage in metres (feet) is displayed. Next to the decompression stop depth, the decompression stop duration of the displayed stage appears in minutes. The display <3m 7:> means that a decompression stop of 7 minutes at a depth of 3m has to be made. When a decompression stop has been finished, the next higher decompression stop is displayed. When all decompression stops have been made, the arrow DECOSTOP extinguishes and the arrow NO STOP reappears. The indication of time on the lower right shows the no-stop time again.
5 Functions at the surface

5.1 End of a dive

After reaching the surface (<0.8 m/3 ft) Smart remains in dive mode for 5 minutes. The delay allows for surfacing for a short period for orientation. After 5 minutes the dive is closed and it is entered into the logbook.

5.2 Desaturation time

For the calculations of the desaturation and no-fly time it is assumed that the diver breathes air while on the surface.
DESAT , desaturation time in hours and After the dive has been closed minutes and, if available, oxygen toxicity is displayed. Desaturation time is determined either by oxygen toxicity, nitrogen saturation or the regression of microbubbles, depending on which requires the longer time. Oxygen toxicity (<CNS O2>) is displayed and adjusted until the value becomes 0%. Desaturation time is indicated until the next dive or until it reaches zero. The display is switched off to save energy three minutes after the last manipulation is made. The calculations are nevertheless continued in the background.
Oxygen toxicity Desaturation time 5.3 No-fly time No-fly time Do not fly icon
The <no-fly time> is indicated beside the icon <do not fly>. <No-fly time> is the time in hours that should pass before a flight and is displayed and adjusted until the value becomes 0 hours.

2000 m 6560 ft 1000 m 3280 ft 0m
815 mbar 11.82 psi 905 mbar 13.12 psi

6.2 Prohibited altitude

Smart shows via flashing altitude segments while at the surface to which altitude the diver may not rise.
Ascent to altitude range 3 and 4 prohibited. Max. allowed altitude: 2650 m (8694 ft).

Max. altitude:

850 m 1650 m 2650 m 4000 m 2790 ft 5413 ft 8694 ft 13120 ft The ascent prohibition can also be displayed together with an altitude range Example: you are at 1200 m (3937 ft) (altitude range 1) and you may ascend to range 2 only (2650 m / 8694 feet). You may not rise to the altitude range 3 or 4.
6.3 Decompression dives in mountain lakes In order to assure optimal decompression even at higher altitudes, the 3m (10 % ft) decompression stage is divided into a 4 m (13 ft) stage and a 2 m (7 ft) stage in altitude ranges 1, 2 and 3. The prescribed decompression stop depths are, in sequence, 2m / 4m / 6m / 9m (7 ft / 13 ft / 20 ft / 30 ft).
Altitude range 4: no deco data COM no RBT
If atmospheric pressure is below 620 mbar (8.99 psi) (altitude higher than 4100 m / 13450 ft above sea level), no decompression data is calculated and displayed (automatic gauge mode). In addition RBT (COM) and the dive planner are not available anymore. The oxygen toxicity and the tank pressure (COM) are still indicated.

IV Diving with microbubble levels (MB)
The following chapter deals with the characteristics of diving with microbubble levels (MB levels). For general information about displays and features of diving with Smart see chapter III. Microbubbles are tiny bubbles that can build up inside a diver's body during any dive and normally dissipate naturally during an ascent and on the surface after a dive. Dives within no-stop time and observance of decompression stops do not prevent the formation of microbubbles in the venous blood circulation. Dangerous microbubbles are those migrating into the arterial circulation. The reasons for the migration from the venous blood circulation to the arterial circulation can be a great many microbubbles collecting in the lungs. UWATEC has equipped Smart dive computers with a new technology to protect from microbubbles. The diver chooses according to his/her needs an MB level and influences through it the level of protection from microbubbles. Diving with MB levels requires additional ascent stops (level stops), the ascent is slowed down and the body gets more time to desaturate. This works contrary to the formation of the microbubbles and increases the safety. Smart features 6 microbubble levels (L0-L5). Level L0 corresponds to UWATEC's well-known decompression model ZH-L8 ADT and does not require level stops due to microbubble formation. Levels L1 to L5 offer additional protection from microbubble formation with level L5 offering the highest protection. Similar to the display of information during decompression dives or dives within no-stop time, Smart displays depth and duration of the first level stop as well as the total time of ascent as soon as the MB no-stop time has run out. As the MB no-stop time is shorter than the ordinary no-stop time a diver will be required to carry out a stop (level stop) sooner than a diver using level L0. If a diver ignores a required level stop, Smart will change over to a lower MB level and the dive can not be completed with the initially chosen MB level. For example, if a diver sets level L4 on Smart prior to the dive and during the dive ignores the stops recommended Smart will automatically adjust the setting to level L3 or lower. 1 Comparison of dives with MB level L0 and MB level L5 When two Smarts are used simultaneously, one unit is set for example to MB level L5, the other to L0, the no-stop time will be shortened and level stops will be required before the diver has the obligation of a decompression stop. These additional level stops help dissipate the microbubbles.

Setting an incorrect mixture carries an inherent risk of decompression sickness and/or oxygen toxicity! An incorrect gas mixture can be lethal! Even before a dive in gauge mode, make sure that the set gas mixture corresponds to the gas mixture currently used. If you are diving trimix or any mix other than oxygen/nitrogen with an oxygen percentage of 21% or higher, input the correct percentage value for the oxygen. The computer will track oxygen exposure correctly and exaggerate the nitrogen loading. If you are diving trimix or any mix with a percentage of oxygen lower than 21%, set the computer to 21% oxygen. The computer will exaggerate both the oxygen exposure and the nitrogen loading.
Enabling the gauge mode (Switching back to the regular dive computer mode) To use the Smart in gauge mode, you must rst enable the computer via SmartTRAK and the infrared interface. Choose "Dive Computer Settings" under the "Options" pop-up window in SmartTRAK. Once the "Dive Computer Settings" dialog box opens, the PC will "write" rst "read" the existing settings in the dive computer. Click on "ON" ("OFF" to switch back to the regular dive computer mode) under "Gauge Mode", then click on the right icon in the top row to "write" the changes to the dive computer. The dive computer will now show "OnG" on the display.

Diving in gauge mode

In gauge mode oxygen toxicity is not displayed, but it is calculated in the background based on the set oxygen mixture. When the calculated value reaches 75% and 100%, an attention beep and an alarm go off, respectively.
The following information is displayed in gauge mode: Icon for microbubble level L1-L5

Diving after violating the dive computer If the computer has been violated by not respecting a mandatory decompression stop, for instance, the computer will lock out for 24 hours. Gauge mode will not be available during the entire lock-out time.

VI Dive planner

Basis of the planning:
Smart is equipped with a dive planner which allows the planning of no-stop dives with freely determinable surface intervals. selected fraction of oxygen (O2% Mix) selected microbubble level water temperature of the most recent dive altitude range (if any) status of saturation at the time the dive planner is selected assuming a normal workload of the diver and observance of the prescribed ascent rates. If two or more divers using computers are planning a dive, planning for all divers has to be based on the dive computer showing the shortest no-stop times. Failure to do this may lead to serious injury or death from decompression sickness.

1 Planning a no-stop dive
With the contacts B and or B and you can select the dive planner at the surface.
Microbubble warning (Do not dive) Duration of the warning
The microbubble warning and its duration are displayed if Smart detects an increased risk due to the accumulation of microbubbles.
Enter the dive planner with B and E.
The input window for the time interval is displayed if there was a remaining desaturation (DESAT) before the dive planner has been selected. This surface interval between now and the beginning of the dive can be changed with the contacts B and + or B and in steps of 15 minutes.
Input of the surface interval Icon for microbubble level L1-L5
If a microbubble warning (no dive) and its duration has been displayed, Smart proposes this time rounded up to the next 15 minutes as surface interval. If the proposed interval is shortened, the microbubble warning appears.
With B and E you confirm the displayed interval (if applicable), then Smart starts scrolling the no-stop times. The no-stop times are displayed in 3 metre increments (10 ft) and are displayed for every increment for about 3 seconds. The process starts at 3 metre (10 feet). If a microbubble level has been selected (L1 to 5), Smart shows the microbubble no-stop time instead of the no-stop time.
No-stop time or MB no-stop time
Depths deeper than the MOD for the selected gas (O2 mix) are not displayed. On page 20 you will find further information and safety considerations regarding the microbubble warning.
