[. . . ] Smart Z ® 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. [. . . ] 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 start flashing. 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 Z is in the no-stop phase. Start ascent at once. 4 sec WARNING % RBT < 3 minutes WARNING % RBT = 0 minutes 4. 11 Decompression information No-stop time is displayed if no decompression stops are necessary. The figures indicate no-stop time in minutes. NO STOP is visible if no NO STOP · No-stop display "99:" means remaining time of 99 minutes or more. · No-stop time is calculated on line and influenced by the current workload and current water temperature No-stop time 4 sec CNS O2% WARNING If no-stop time drops below 3 minutes, an audible attention signal is activated and the no-stop value begins to flash. 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. Dives that require decompression stops are not recommended. UWATEC® Smart dive computers NO STOP WARNING 22 4 Functions during the dive Decompression values III CNS O2% DECO STOP Decompression stop depth Decompression time 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 NO STOP DECOSTOP extinguishes and the arrow reappears. The indication of time on the lower right shows the no-stop time again. Deco stop depths deeper than 27m (90 ft) are displayed as "­ ­ : ­ ­ ". The decompression alarm is activated if the decompression stop is ignored. The arrow DECOSTOP , 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. [. . . ] Now insert the new battery, with "+" pointing upwards, into the battery compartment. After battery replacement the transmitter will perform an automatic test and switch into ready mode after 60 seconds. UWATEC Smart dive computers ® 37 English VIII Appendix WARNING 10. Check the proper position of the guide slots on the electronic support and in the transmitter cap. Slide the transmitter cap carefully back into its proper position. Mount the transmitter on the HP outlet of the first stage of the regulator and check transmission and pairing. [. . . ]
