® ® ® PRIME TEC SWISS MADE BY UWATEC AG Français English Operating Manual Deutsch Safety considerations You must carefully read and understand this entire manual before using your Aladin® PRIME or Aladin® TEC. 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 Aladin® PRIME or Aladin® TEC. WARNING Guidelines for the use of Aladin® PRIME and Aladin® TEC: The following guidelines for using Aladin® PRIME and Aladin® TEC 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. · Aladin® PRIME and Aladin® TEC are designed for dives with Nitrox (Aladin® PRIME max.50%O2, Aladin® TEC max.100%O2) and compressed air (21%O2) only. Do not use Aladin® PRIME or Aladin® TEC 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 Aladin® PRIME and Aladin® TEC with open circuit breathing systems. Aladin® PRIME and Aladin® TEC must be set for a determined gas mixture. · Only use Aladin® PRIME and Aladin® TEC for diving with an independent breathing apparatus. Aladin® PRIME and Aladin® TEC are not designed for long term exposures with Nitrox. · Always observe the visual and audible alarm signals. Avoid situations of increased risk which are marked with a warning sign in this operating manual. · Aladin® PRIME and Aladin® TEC have a ppO2 warning. The default limit is set at 1.4 bar ppO2max. On Aladin® TEC it can be changed between 1.2 and 1.6 bar. · Frequently check the "oxygen clock" (CNS O2). 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. Aladin® PRIME and Aladin® TEC give 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 Aladin® PRIME or Aladin® TEC fail 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. Aladin® PRIME and Aladin® TEC do not substitute for a dive buddy. · Only make dives that are appropriate to your level of dive training. Aladin® PRIME and Aladin® TEC do not increase your knowledge of diving. · 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. 2 I UWATEC® Aladin® dive computers Safety considerations 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 Aladin® PRIME and Aladin® TEC! 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. · Do not attempt a repetitive dive if the microbubble warning is visible on the display. · 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. · Diving after a reset of the remaining saturation (reset, see page 41, or battery replacement, see page 45) may lead you into potentially hazardous situations which could result in death or serious injury. After a reset of the remaining saturation do not dive for at least 48 hours. NO I · · · · Altitude and diving · Do not dive at altitudes higher than 4000m (13000 feet). · After a dive do not rise to altitudes that Aladin® PRIME or Aladin® TEC prohibit via the flashing altitude range number (see page 27). Flying after diving · After diving, wait at least 24 hours prior to flying. Aladin® PRIME and Aladin® TEC dive instruments are a personal protective equipment in compliance with the essential safety requirements of the European Union directive 89/686/EEC. RINA SpA, Via Corsica 12, I-16128 Genoa, notified body no. 0474, have certified the conformity with the European Standard EN 13319:2000.

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. Aladin® includes this in the calculations and displays the necessary information: Fraction of oxygen: The fraction of oxygen in the Nitrox mixture can be set between 21% (normal compressed air) and 50% (TEC: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). When you enter the settings for the gas mixture, Aladin® will display the ppO2 max. limit setting and the corresponding MOD. Aladin® warns the diver audibly and visually once the depth is reached at which the ppO2 reaches the maximum allowed value ->23. · Default setting of ppO2 max. is 1.4 bar. TEC The value of ppO2 max. can be set by means of SmartTRAK or with "set 1" between 1.2 and 1.6 bar (->40). It can also be reduced at the time of setting the gas mixture (->18). · The CNS O2% value/alarm is not influenced by the selected ppO2max. setting. 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 ->23. ppO2 0,21 bar CNS O2% decreases 0,5 bar CNS O2% increases ppO2 max. WARNING Nitrox diving may only be attempted by experienced divers after proper training from an internationally recognized agency. 16 III UWATEC® Aladin® dive computers 2 Attention messages and alarms Aladin® III draws the diver's attention to certain situations and warns the diver of unsafe diving practices. Attention messages and alarms are visual and / or audible. · The audible attention messages can be switched off in "set 1" ->41 or SmartTRAK. With SmartTRAK they can be switched off selectively. · In addition, the sound can be turned off completely in "set 2" ->44. If you turn off the sound you will have no audible warnings. Without audible warnings you could inadvertently get into potentially hazardous situations which could result in death or serious injury. Serious injury or death may result from failing to immediately respond to alarms given by Aladin®. 2.2 Alarms 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. WARNING WARNING 2.1 Attention messages Attention messages are communicated to the diver visually by symbols, letters or flashing figures.

All settings can be checked and changed directly at Aladin® or via SmartTRAK. Chapter 3 describes the most common settings. On the next page you will find an overview with all possible Aladin® settings and page references. 3.1 Setting the gas mixture and TEC ppO2 max WARNING Before every dive and after changing the tank, make sure that the settings for the gas mixture correspond with the current mixture used. An incorrect setting causes Aladin® 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, Aladin® must be in user mode (time of day display). or until 1. Push appears. or until the symbol for the setting of the O2 mixture 2. Confirm that you wish to change the displayed oxygen fraction by pushing . 3. Change the oxygen fraction in increments of 1% by pushing or . Aladin® will display the current fraction of oxygen, the maximum partial pressure limit* (ppO2 max) and the MOD. *TEC As pre-set by means of SmartTRAK or "set 1". 4. Confirm the selected percentage with . Max. Operating Depth MOD Change the O2% mix by (+) and (-) ppO2max. 5.

WARNING If you have chosen the option "Water contacts off" ("set 1" or SmartTRAK), Aladin® will turn on with a delay of up to 1 minute into the dive. This will affect functioning of the computer. Make sure that the computer is on before starting the dive. After immersion, starting at a depth of about 0.8 m (3 ft), all diving functions are monitored, i.e. depth and dive time displayed, maximum depth stored, saturation of tissues calculated, no-stop time or decompression prognosis determined, ascent rate controlled and displayed and the correctness of the decompression procedure supervised. 4.2 TEC Setting bookmarks During the dive you can create bookmarks in your dive profile by pressing . The logbook icon appears for 4 seconds and an audible signal confirms the creation of the bookmark. These bookmarks will be graphically displayed in the dive profile of SmartTRAK. To visualize the bookmarks on the dive profile, the box "Generate bookmarks" under "Program options" in SmartTRAK must be selected. 4.3 Dive time Dive time DEPTH DIVE TIME NO STOP STOP The whole time spent below a depth of 0.8m (3 feet) is displayed as dive time in minutes. The time above 0.8m (3 feet) is counted as dive time only if the diver descends again below 0.8m (3 feet) within 5 minutes. While the dive time is running, the colons on the right of the figures are flashing in one second intervals. Maximum dive time displayed is 199 minutes. If a dive lasts longer than 199 minutes the dive time display starts again at 0 minutes. TEC Half time alarm (turn around alarm) If half of the set maximum dive time (->39) has elapsed, an audible signal goes off and flashes for 1 minute. WARNING WARNING TEC Set dive time has elapsed An audible signal goes off and the dive time starts flashing. 4.4 Current depth / O2% mix Current depth is given in 10 cm increments (1 foot).
