[. . . ] Smart PRO Smart COM ® SWISS MADE BY UWATEC AG Français English Operating Manual Deutsch Safety considerations You must carefully read and understand this entire manual before using your new computer. Even if you follow the instructions of this manual in a careful manner, it is still possible that you may be seriously injured or die from decompression sickness, oxygen toxicity or some other inherent risk of scuba with Nitrox or compressed air. Unless you are fully aware of these risks and are willing to personally accept and assume responsibility for those risks, do not use the computer! WARNING Guidelines for the use of your UWATEC dive computer: The following guidelines are derived from the latest medical research and the recommendations of the American Academy of Underwater Sciences for diving with diving computers. Following these guidelines will greatly increase your safety while diving, but cannot guarantee that decompression sickness or oxygen toxicity will not occur. [. . . ] · ppO2 max should not be set higher than 1. 6 bar WARNING 16 UWATEC® Smart dive computers 4 Functions during the dive C III 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. DEPTH DIVE TIME CNS O2% NO STOP MAX. DEPTH DECO INFO Oxygen toxicity 4 sec DEPTH WARNING % DIVE TIME C 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. CNS O2% % NO STOP MAX. DEPTH DECO INFO DEPTH NO C % DIVE TIME WARNING CNS O2% When oxygen toxicity reaches 100%, an audible alarm goes off every 4 seconds. <CNS O2>, the precentage value and the ascent arrow flash. Start ascent at once. % NO STOP MAX. DEPTH DECO INFO · 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. TANK DATA bar 4 sec TANK DATA RBT WARNING 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). 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. bar RBT 4 sec TANK DATA bar RBT WARNING UWATEC® Smart dive computers 17 English 4 Functions during the dive 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 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. A graphic representation of RBT is on page 11. WARNING 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. 4 sec WARNING TANK DATA 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. bar RBT RBT < 3 minutes WARNING The RBT value should never reach <0:>. With RBT=0 the remaining tank reserve may not be sufficient for the ascent. When the last minute has passed (RBT=0) an audible alarm is activated every 4 seconds. [. . . ] The battery replacement is carried out by a SCUBAPRO UWATEC subsidiary. Smart is checked for its technical integrity at the same time. Do not attempt to have the batteries changed by anyone other than an authorised SCUBAPRO UWATEC dealer. · · · · WARNING 32 UWATEC® Smart dive computers VIII Appendix 3 COM Conversion of tank pressure VIII Tank pressure indicated in the lower display may differ from the information given by a manometer/ pressure gauge. Smart COM displays pressure always converted to a temperature of 20°C / 68°F, whereas the mechanical pressure gauge displays the current pressure influenced by temperature. [. . . ]
