® ® ® 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.
