  • Page 6 Safety considerations ® Guidelines for the use of Aladin Pro Nitrox: The following guidelines for using Aladin ® Pro Nitrox 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 will not occur.
  • Page 7 Safety considerations ® – On all dives with the Aladin Pro Nitrox, make a safety stop for three to five minutes within the ten to thirty feet zone. – Never use the Aladin ® Pro Nitrox for repetitive, “square“ dives deeper than 60 feet. A square dive is a dive that is performed for its duration at a uniform depth.
  • Page 8 Safety considerations ® – You MUST follow the ascent rates as indicated by the Aladin Pro Nitrox, and should the computer fail for any reason, you must ascend at a rate of no greater than 60 feet per minute. – You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin ®...
