Page 5 CONTENTS The RATIO iX3M when diving Dive Screen 48 Main Data Current dive’s profile: Tissues saturation when diving: The diagram represents the 16 tissues which are taken into consideration by the two decompressive algorithms (BUL or VPM). The yellow lines represent the nitrogen levels .
Page 6: Introduction
The RATIO® iX3M computer includes decompressive algorithms supporting, according to the diﬀ erent models, Air Nitrox, Normoxic Trimix dives (iX3M DEEP), Trimix and CCR (iX3M TECH + and iX3M REB) and its processor calculates in real time your dive’s speciﬁ c deco proﬁ le; all this ensure calculation ﬂ exibility and your personal safety.
Page 7: Importan Warnings
Importan Warnings General Warnings It is necessary read this manual carefully before using the computer RATIO®. A wrong use of this computer or its accessories will nullify the warranty and could cause permanent damages to the device and/or its accessories.
Page 8 • The computer doesn’t replace the learning of the diving decompression charts which we recommend to have always as backup along with a depth gauge and a watch. • It is forbidden to share a unique computer for two divers while diving; every diver must have his/her device at his/her wrist, which can give information to him/her only.
Page 9: Danger Warning
Danger Warning The computer IS NOT meant for a PROFESSIONAL use. The computer is meant exclusively for a sport, recreational or technical use. • A use which is not compliant to what has been said above, could expose the diver to an increasing risk of incurring in the Decompression Disease (DD).
Page 10 • We recommend to do dives within the safety curve, to reduce the risks inherent to the Decompression Disease (DD). • We recommend dives not deeper than 40 mt or according to the oxygen percentage contained inside the tank. Maximum PPO2 1,4 BAR •...
Page 11: Diving With Mix
Diving with Mix Setting the gas portion contained in the tank, the computer will take into consideration only whole numbers. So, for example, in case of a veriﬁ ed gas percentage of 32,8% the value to be setted will be the lowest, that is 32%. Do not round oﬀ...
Page 12: Limits Of Diving Computers
• Do not expose the computer to the sun directly or to heat sources higher than 50°C. Store the computer in a fresh (5°C-25°C) and dry place. • Do not attempt to open, modify or repair the computer by yourself. You must always address to a RATIO dealer. • Do not put the computer inside a hyperbaric chamber.
Page 13 • Warranty falls if the computer is opened by a not authorised assistance centre. • The RATIO iX3M computer is designed to be waterproof in sea water but, at the end of every dive, it must be well rinsed in fresh water and it must not be dried exposing it at the direct sun light or at heat sources.
Page 14: Computer's Technical Characteristics
Computer’s technical characteristics Hardware The computer is fully built in POM C with Makrolon cover, allowing an extreme resistance to hits and to corrosion. The screen is provided with a Display TFT 100%; its matrix has 320x240 pixel resolution Particular commitment has been put in developping a navigation system allowing the diver to have an easy and intuitive access to all settings.

For RATIO iX3M Deep: Operating on level systems it is possible to set up the conservatism desired. For RATIO iX3M Tech+ ed iX3M Reb: Using the Bühlmann ZHL-16B algorithm there is the possibility of an exact choice of the Gradient Factors. Using the VPM-B algorithm there is the possibility of an exact choice of the inert gases’ critical bubble radius.

Tissues saturation update in sleep mode: 1 minute. Number of stored diluent gases: iX3M Deep: 3 gases iX3M Tech+: 10 gases iX3M Reb: 10 gases +3 diluents Memory: 100 diving hours. Maximum diving time: 1999 minutes. Adaptative logic intuitive software.
Page 17: How To Recharge The Battery
The recharge is to be carried out by connecting the device to your PC by its USB cable or connecting it at any USB port To recharge the RATIO iX3M we recommend to use a wall USB plug (like the one of your mobile/tablet). If you decide to use a PC USB plug, make sure that the PC doesn’t interrupt the electricity ﬂ...
Page 18 After having installed one APP or having updated the operative system, we recommend to carry out a complete battery charge cycle. After every update the RATIO iX3M always shows the sentence “battery out of power, recharge”. Attention: Do not leave the device completely out of power for a long period (e.g. 6...
Page 19: Diving In Cold Or Freezing Waters
Diving in cold or freezing waters The RATIO iX3M can be used even in case of dives in cold or freezing waters (<3°C); however, the exposure at particularly low temperatures, may aﬀ ect negatively on the battery residual voltage. When diving in cold or freezing waters, the battery voltage may decrease more rapidly than normal. So, we recommend to recharge the battery before diving in extreme conditions.
Page 20: Dan Dl7
DAN DL7 The RATIO iX3M is 100% compatible with the program for gathering data DAN DL7 of DSL Level 5 100% compatible with The DAN DL7 is a format owned by DAN, which summarizes all necessary information which are DAN DL7 needed for the studies, arranging them to be sent directly to DAN Europe’s central database.

The RATIO iX3M switches oﬀ automatically after 10 minutes of tatal inactivity. After diving the RATIO iX3M activates the Sleep mode modality: after 10 minutes of inactivity it switches the screen oﬀ and deactivates all processes which are not useful for the post-diving de-saturation calculation .

Page 23 Attention: after diving, the humidity in the sensor’s area may compromise the weather forecast. Temperature (on the right): the temperature measured by the RATIO iX3M is the device’s case temperature itself. For this reason, when wearing it at your wrist, it will measure a higher temperature than the environmental one.
Page 24 In case of case of bad weather or after diving, the error might also be of +/-80m. For more precise altitude measurements, use the RATIO iX3M’s “GPS” application. - Main time (in the middle): Expressed in hh:mm in 24 hrs format - Current Lunar phase (on the right): Expressed in ﬁ...
