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. Diving has many inherent risks. 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. · This computer is designed for dives with Nitrox (to a max.100% O2) and compressed air (21%O2) only. Do not use the computer for dives made with other mixed gases. · It is absolutely necessary to check the set mixture before each dive and to compare it to the gas mixture currently used. Always remember: setting an incorrect mixture carries an inherent risk of decompression sickness and/or oxygen toxicity! Maximum deviation from the measured mixture must not exceed 1% O2. An incorrect gas mixture can be lethal! · Only use this computer with open circuit breathing systems. The computer must be set for a determined gas mixture. · Only use this computer for diving with an independent breathing apparatus. The computer is not designed for long term exposures with Nitrox. · Always observe the visual and audible alarm signals of the computer. Avoid situations of increased risk which are marked with a warning sign in this operating manual. · If the ascent arrow appears, start to ascend. · If the flashing ascent arrow appears, start to ascend immediately. · This computer has a ppO2 warning, the default limits of which are set at 1.4 bar ppO2max. This limit can be adjusted via SmartTRAK. An alteration of the ppO2max to higher than 1.6 bar is dangerous and we do not recommend this. · Frequently check the "oxygen clock" (CNS O2), especially in the range higher than 1.4 bar ppO2. Ascend and finish the dive if the CNS O2 exceeds 75%. · Never dive deeper than the Maximum Operating Depth (MOD) pertinent to the gas mixture in use. · Always check the diving limits considering the oxygen content and standard sports diving procedures (decompression sickness, oxygen toxicity). · In accordance with the recommended maximum diving limit of all instructional agencies, do not dive deeper than 40 metres/130 feet. · The danger of nitrogen narcosis has to be taken into consideration. The computer gives no warning about this. · On all dives, with or without dive computer, make a safety stop for at least 3 minutes at 5 metres (15 feet). · All divers using dive computers to plan dives and indicate or determine decompression status must use their own computer, which they take with them on all dives. · If the computer fails at any time during the dive, the dive must be terminated, and appropriate surfacing procedures (including a slow ascent and a 3 to 5 minute safety stop at 5 metres /15 ft) should be initiated immediately. · Comply with the ascent rate and carry out any decompression stop required. If the computer should fail for any reason, you must ascend at a rate of 10m (30 feet) per minute or less. · On any given dive, both divers in a buddy pair must follow the most conservative dive computer for that particular dive. · Never dive without a buddy. Smart Z does not substitute for a dive buddy. · Only make dives that are appropriate to your level of dive training. A dive computer does not increase your knowledge of diving. 2 UWATEC® Smart dive computers Safety considerations I · Always dive with back-up instruments. Make sure that you always use back-up instrumentation including a depth gauge, submersible pressure gauge, digital bottom timer or dive watch, and have access to decompression tables whenever diving with a dive computer. · Avoid repeated ascents and descents (yo yo diving). · Avoid repeated heavy workload while at depth. · Plan the dives to be shorter if they are made in cold water. · After finishing the decompression or at the end of a no-stop dive, the final stage of the ascent should be as slow as possible. · You MUST be familiar with all signs and symptoms of decompression sickness before using this computer! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symptoms occur after a dive! There is a direct correlation between the effectiveness of treatment and the delay between the onset of symptoms and the treatment for decompression sickness. · Only dive with Nitrox after you have been thoroughly instructed by a recognised institution. Repetitive dives · Do not start your next dive before your CNS O2% status has dropped below 40%. · Diving with Nitrox: Make sure your surface interval is long enough (just like diving with compressed air). Plan for a minimum surface interval of two hours. Oxygen, too, needs sufficient time to leave the body. · Match gas mixture to the intended dive. is visible on the display. · Do not attempt a repetitive dive if the microbubble warning · Plan a day without diving once a week. · If you have to change computers, wait at least 48 hours before carrying out your next dive. NO Altitude and diving · Do not dive at altitudes higher than 4000m (13000 feet). · After a dive do not rise to altitudes that the computer prohibits via the flashing altitude segments (see page 25). Flying after diving · After diving, wait at least 24 hours prior to flying.

UWATEC® Smart dive computers 3 English Introduction Congratulations on purchasing a Smart Z dive computer and welcome to UWATEC. From now on you will enjoy the assistance of the most extraordinary dive computer - equipped with UWATEC's most innovative technology - while diving. We thank you for choosing this computer and we hope you will enjoy safe dives in the future! Further information on UWATEC Smart dive computers and other products by UWATEC can be found on our web page at www.uwatec.com. To make this manual easier to read we will use the term 'Smart Z' as an abbreviation for 'UWATEC Smart Z diving computer' throughout this booklet. Safety considerations Dive computers provide divers with data; they, however, do not provide the knowledge how this data should be understood and applied. Dive computers cannot replace common sense! You must therefore carefully read and understand this entire manual before using your Smart Z. Important remarks concerning signal words and symbols This operating manual makes use of the following icons to indicate especially important comments: Remarks Danger!
