! WARNINGS:

• This manual is to be used in conjunction with the Aqua Lung Dive Computer Safety and Reference Manual, Doc. 12-7835. It contains general safety warnings and recommendations for use of this product. • The i550C 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 i550C for nitrox diving. • Before using this product for military or commercial applications, read the recommendations, limitations, and warnings for such use. They can be found at http://www.aqualung.com/ militaryandprofessional/. • 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 i550C. • 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 i550C 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 i550C, 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 i550C 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 i550C. Based on this the diver must decide if the i550C is suitable for the dive activities and dive profiles being planned. • Using an i550C is no guarantee of avoiding decompression sickness. • The i550C 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 i550C's design. If you are following these dive profiles, Aqua Lung advises that you should not use an i550C.

ro c. (2018) 3 Doc. 12-7909-r0 (7/10/19)

• If you exceed certain limits, the i550C 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. • DO NOT use your i550C with supply gas pressures exceeding the working pressure range of 0 to 300 bar (0 - 4350 psi). Excessive pressure will lead to component failure and possible injury due to rapidly expanding components. EUROPEAN UNION REGULATIONS:

• EC type examination conducted by SGS Fimko Oy, Särkiniementie 3 Helsinki, 00211 Finland Notified Body No. 0598 • HP gas pressure sensing components are in conformity with EN250:2014 - Respiratory equipment - open-circuit self-contained compressed air diving apparatus - requirements, testing and marking – clause 6.11.1 Pressure Indicator. EN 250:2014 is the standard describing certain minimum performance requirements for SCUBA regulators to be used with air only sold in EU. EN250:2014 testing is performed to a maximum depth of 50 M (165 FSW). A component of self-contained breathing apparatus as defined by EN250:2014 is: Pressure Indicator, for use with air only. Products marked EN250 are intended for air use only. Products marked EN 13949 are intended for use with gases containing more than 22% oxygen and must not be used for air. • Depth and time measurements are in conformity with EN13319:2000 - Diving Accessories - depth gauges and combined depth and time measuring devices • The air used must comply with EN 12021. EN 12021 is a standard that specifies the allowable contami- nates and component gasses that make up compressed air. This is the equivalent of the USA Com- pressed Gas Association’s Grade E air. Both standards allow very small amounts of contaminants that are not harmful to breathe, but can cause a problem if present in systems using gasses with a high percentage of oxygen. • Electronic instruments are in compliance with Directive 2004/108/EC Electromagnetic compatibility (EMC) EN 61000 part 6-1: Generic Standards - immunity for residential, commercial and light-industrial environments • In accordance with EU regulation 2016/425, may it be known that Pelagic as manufacturer of this product issues a Declaration of Conformities, available here http://www.pelagicnet.com/dc

! CAUTION: Transmitters and gas integrated dive computers marked EN 250 are certified for use with air only. Trans- mitters and gas integrated dive computers marked EN 13949 are certified for use with Nitrox only. RISK ASSESSMENT:

The air integrated dive computer is intended to address the risk of breathing gas loss. This is accom- plished by monitoring the level of remaining gas in the UBA (Underwater Breathing Apparatus) and pro- viding the diver with a continuous readout of the remaining gas supply and user set alarms.

The digital pressure indicator has several user defined alarms. Alarms are addressed in the user manual beginning on page 23 (items 1, 5, 6; 7).

1. Audible alarm feature allows the diver to set audible alarms to ON or OFF. 5. Dive Time remaining can be set for a specific reserve of dive time remaining, dive time is calculated based on air time and no deco time. 6. Turn – set a pressure to alarm at designated turn pressure 70 to 205 BAR (1000 to 3000 PSI) 7. Pressure - set a pressure to alarm at end of dive pressure 20 to 105 BAR (300 to 1500 PSI)

In addition, recreational diving requires that the diver be fully trained in order to acquire filled gas cylin- ders or access many diving venues. Diver training focuses on the proper use of the pressure indicator and dive planning. This is to assure that the diver is able to correctly use the pressure indicator to complete the dive with a reserve supply of breathing gas.

The i550C Log and Diverlog + Download data is stored separately in different partitions of the memory. The Log only stores a short summary of each dive. Alternately, the Diverlog + Download function stores much larger files for each dive. For this reason, it is normal to see dives stored in the i550C's onboard Log that have already been overwritten in the Diverlog + Download Partition.

NOTE: New data will automatically overwrite the oldest data in memory when the memory becomes full. The i550C Log and Download data is stored separately in different partitions of the memory. The Log only stores a short summary of each dive. Alternately, the Down- load function stores much larger files for each dive. Depending on the chosen settings and dive durations, it is possible to see dives stored in the i550C's onboard Log that have already been overwritten in the Download Partition. Choosing a longer Sample Rate interval will consume less memory per dive. Remember to download your dives more frequently if you are using a shorter Sample Rate interval.

GAS SWITCHES

! WARNINGS: • Historically, many accidents and near misses have occurred by switching to the wrong gas at the wrong depth. DO NOT attempt gas switch decompression dives without proper education and training to do so from an internationally recognized training agency. • Diving deeper than 39 m (130 ft), will greatly increase your risk of decompression sickness. • Decompression diving is inherently hazardous and greatly increases your risk of decompression sickness, even when performed according to the dive computer's calculations. • Using an i550C is no guarantee of avoiding decompression sickness. • The i550C 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 i550C's design. If you are following these dive profiles, Aqua Lung advises that you should not use an i550C. • If you exceed certain limits, the i550C 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.
