It is essential to read this user manual before using the RATIO computer. The incorrect use of the computer or its accessories will void the warranty and may cause permanent damage to the com-

puter itself and / or its accessories. The dive computer is NOT A SUBSTITUTE to scuba diving training and should be used only by divers who have been properly trained The RATIO computer is an auxiliary tool to diving, therefore it is mandatory to always have an ade-

quate table in order to perform the decompression phase in the case of malfunction to the unit Diving carries risks related to decompression sickness, oxygen toxicity and other inherent risk and even careful perusal of this manual and use of this instrument does not rule out potential dangers. Anyone who does not understand or does not knowingly accept these risks should not dive with the iDive computer. Diving has some inherent risks that can never be completely excluded. No dive table or compu-

ter can ever ensure that there are no Decompression Illness risk (DCI) or Central Nervous System 6 Cautions Oxygen Toxicity even if the diver scrupulously and correctly follows the instructions of dive tables or computers. The computer is not able to take into account individual physiological variations that can alter day to day and for this reason it is good practice to use this instrument in a conservative and precau-

tionary manner, remain well within the limits set by the computer in order to minimize the risk of decompression sickness and oxygen toxicity to the central nervous system. The computer does not replace decompression training of tables that you always want to have as a backup together with a depth gauge and watch. It is prohibited to share a single computer for two divers while diving, each diver must carry their own instrument which provides information only to them. It is prohibited to dive with a computer that did not take into account previous dives made by the diver, its calculation can never take into account data that it does not know. Personal Safety factors: carefully read the detailed instructions on how to set up and choose the appropriate level. The 0 to 3 value scale provides a higher level of conservatism with the increase of its value. 7 Cautions Danger warnings The computer is NOT intended for PROFESSIONAL use! The computer is intended for sports use only. Non compliance to the above may expose the diver to an increased risk of incurring decompression illness (DCI) It is therefore not recommended for commercial or professional diving. Before diving you must check the battery level, DO NOT dive with the battery level of 30% or lower, check that the display does not show any sign of malfunction and that it is legible. Check that the settings correspond to those desired. 8 Cautions Keep in mind that our body has daily variations of which the computer cannot take into account. You must avoid all behavior that increase risks associated with decompression sickness such as rapid ascents, yo-yo diving, decompression stop obligations, dives with surface intervals too close toge-

ther and by any other behavior not dictated by common sense and training. However the use of the instrument, does not allow its use without due preparation through specific training. Failure to follow the basic rules of diving exposes the diver to life threatening circumstan-

ces. We recommend diving within the safety curve in order to reduce risks associated with decom-

pression sickness. We recommend not exceeding 40 meters diving or based on the oxygen % value within the cylinder, max 1.4 BAR PpO2. Exposure to higher values exposes the diver to life-threatening conditions. We do not recommend diving with Mandatory Safety Stops. Comply with the ascent rate recommended by the instrument, an excessive ascent rate exposes the diver to life threatening conditions. The computer calculates the total time of ascent but may be longer than that displayed according to certain parameters that the computer recalculates throughout the dive, try to use the correct ascent 9 Cautions speed, observing the depth stops displayed helps meet this duration. No FLY Time: it is prohibited to board a plane if the NO FLY TIME icon on the display is still on. Re-

member to plan the last dive of the series taking into account the recommendations provided by DAN (Divers Alert Network). Even if you meet all the set intervals, we cannot exclude the onset of decompression disease while flying after diving. Gas mix Setting the oxygen fraction contained in a cylinder the computer will only take into account whole numbers such as when 32.8 percentage of oxygen is used, a whole number value that is less than 32 should be set. Do not round to a top number as this will underestimate calculations relating to the nitrogen. Check the PpO2 max settings and never exceed the 1.4 BAR value. DO NOT DIVE without checking the contents of the cylinder with declared reliable instruments. Check the gas settings on the computer to match those contained in the cylinder with which you will dive with. 10 Cautions Diving with Nitrox requires specific training, DO NOT dive without due training. Exceeding the maxi-

mum PpO2 settings and those recommended imposes an immediate ascent to a lower level and in the event of a CNS value (Central Nervous System) approaches the recommended limits we advise a reduction of oxygen exposure. Before a dive Use the dive computer only after reading the instruction manual in its entirety and you thoroughly understand its operation. In cases of doubt or questions, please contact your dealer before diving. It important to understand that every diver is totally responsible for their own safety. Diving with gas mixtures involve different risks from those associated with standard air diving. You need proper training to learn how to understand and avoid such risks, which are not readily ascer-

tainable. These risks include possible serious injury or death. 11 Cautions Limits of the dive computer The computer reflects the latest guidelines on diving safety but keep in mind that these studies are to be considered of theoretical basis and processed to reduce but not eliminate the risk of de-

compression sickness. Care and Maintenance Keep your computer clean and dry. Do not expose the computer to chemicals, including alcohol. To clean the computer use only fresh water to remove all saline deposits. Leave the computer to dry naturally, do not use jets of hot or cold air. Do not expose the computer to direct sunlight or sources of heat above 50 C. Keep your compu-

ter in a cool and dry place (5C - 25C). Do not attempt to open, modify or repair the computer on your own. Always contact the manu-

facturer through an authorized service provider. Do not put the computer into a hyperbaric chamber. The computer is designed for accuracy in the readings of +/- 2%. European rules require that the 12 Cautions unit is controlled periodically from the point of view of accuracy in reading, the depth and time. The level of precision required by European standards is +/- 3.5%. The warranty is voided if the endcap is removed from a non-authorized service center. The computer iDive is built to withstand use in sea water but at the end of the dive you have to rinse well with fresh water and do not expose to direct sunlight or heat sources to dry. Check the display there are no traces of moisture on the inside. Note: Do not groped to open the computer for any reason in case of problems contact your service through the retailer where it was purchased. 13 Specifications Your computer is made in all stainless steel 316L with sapphire glass, allowing in this so a high impact resistance and corrosion resistance. Display is equipped with an LCD Display 100% matrix. Particular effort has been put in the development of a navigation system that allows the diver access to the settings in an easy and intuitive.
