[. . . ] 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. [. . . ] 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. 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 audible alarm on exceeding the RBT is suppressed at depths less than 6. 5 m (21 ft) if Smart COM is in the no-stop phase. Start ascent at once TANK DATA bar RBT RBT = 0 minutes 4. 10 Decompression information No-stop time is displayed if no decompression stops are necessary. The figures indicate no-stop time in minutes.

If no-stop time is less than 1 minute, the no-stop display shows the flashing value "0". In order to prevent a decompression dive, ascend slowly until the no-stop time is 5 minutes or more.

DEPTH DECO INFO Ignored decompression alarm The decompression alarm is activated if the decomDECOSTOP , the decompression stop duration and decompression stop depth begin to flash and an audible alarm goes off. Due to the formation of microbubbles, decompression can increase massively if a decompression stop is ignored. When the surface is reached during the decompression alarm, the arrow DECOSTOP , the decompression stop duration and decompression depth continue flashing, in order to point to the risk of a decompression accident. The SOS mode is activated 3 minutes after the dive if corrective action is not taken (-> 10). WARNING pression stop is ignored. The arrow If the total (cumulative) duration of the decompression alarm is longer than one minute, it is entered in the logbook. [. . . ] The surface of your Smart housing can be treated with silicone grease. · Do not clean Smart with liquids containing solvent (apart from water). Take the dive computer to an authorised SCUBAPRO UWATEC dealer in order to change the batteries. The battery replacement is carried out by a SCUBAPRO UWATEC subsidiary. [. . . ]
