WARNINGS:
• The i550 is intended for use by recreational divers who have successfully completed a internationally
recognized course in scuba diving (for air use) and diving with enriched nitrogen-oxygen (nitrox)
breathing gas mixtures (for nitrox use).
• It must not be used by untrained persons who may not have knowledge of the potential risks and
hazards of scuba diving and diving with enriched nitrogen-oxygen (nitrox) mixtures.
• You must obtain scuba certification in diving with enriched nitrogen-oxygen mixtures (nitrox) before
using the i550 for nitrox diving.
• It is NOT for use by military and commercial divers.
• As with all underwater life support equipment, improper use or misuse of this product can cause
serious injury or death.
• Never participate in sharing or swapping of a dive computer.
• Conduct your dives in such a manner so as to insure that you continuously check the computer's
proper function.
• Read and understand this owner’s manual completely before diving with the i550.
• If you do not fully understand how to use this dive computer or if you have any questions, you should
seek instruction in its use from your authorized Aqua Lung dealer before you utilize this product.
• If your i550 stops working for any reason while operating, it is important that you have anticipated
this possibility and are prepared for it. This is an important reason for not pushing the tables, oxygen
exposure limits, or entering decompression without proper training. If you dive in situations where
your trip would be ruined or your safety would be jeopardized by losing the use of your i550, a
backup instrument system is highly recommended.
• Each numeric and graphic display represents a unique piece of information. It is imperative that you
understand the formats, ranges, and values of the information represented to avoid any possible
misunderstanding that could result in error.
• Remember that technology is no substitute for common sense. The dive computer only provides
the person using it with data, not the knowledge to use it. Remember also that the dive computer
does not actually measure and test the composition of your body tissue and blood. Using an Aqua
Lung dive computer, just as using any other Decompression Tables, is no guarantee of avoiding
decompression sickness. Every diver’s physiology is different and can even vary from day to day. No
machine can predict how your body will react to a particular dive profile.
• Diving at high altitude requires special knowledge of the variations imposed upon divers, their
activities, and their equipment by the decrease in atmospheric pressures. Aqua Lung recommends
completion of a specialized altitude training course by a recognized training agency prior to diving in
high altitude lakes or rivers.
• Repetitive dives in a series should only be conducted at the same altitude as that of the first dive of
that series. Repetitive dives made at a different altitude will result in an error equal to the difference in
barometric pressure, and possibly a false dive mode with erroneous data.
• If the i550 is activated at an elevation higher than 4,270 m (14,000 ft), it will immediately shutdown.
• Decompression diving or diving deeper than 39 m (130 ft) will greatly increase your risk of
decompression sickness. This should only be attempted by those properly trained and certified
in decompression diving. It is important to completely understand the features, functions, and
specifically the limitations of the i550. Based on this the diver must decide if the i550 is suitable for
the dive activities and dive profiles being planned.
• Using an i550 is no guarantee of avoiding decompression sickness.
• The i550 enters Violation Mode when a situation exceeds its capacity to predict an ascent procedure.
These dives represent gross excursions into decompression that are beyond the boundaries and
spirit of the i550's design. If you are following these dive profiles, Aqua Lung advises that you should
not use an i550.
• If you exceed certain limits, the i550 will not be able to help you get safely back to the surface. These
situations exceed tested limits and can result in loss of some functions for 24 hours after the dive in
which a violation occurred.
