  • Page 8: Introduction

    Introduction Thank you for having purchased the RATIO® computer. RATIO®, with the quality of its products, always stands by you to guarantee comfort, leisure and safety when diving. The RATIO® computer that you have purchased is extremely innovative, with a software allowing you to carry out both recreational and technical dives.

  • Page 9: Important Warnings

    Important 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 10 • 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. • Never 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 11: 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 Sickness (DCS).
  • Page 12 • We recommend to do dives within the safety curve, to reduce the risks inherent to the Decompression Sickness (DCS). • We recommend dives not deeper than 40 mt or according to the oxygen percentage contained inside the tank. Maximum PPO2 1,4 BAR •...

    Diving with Mix The safety approximation of the Mix has to be decided by the diver. If you are not sure about the EAN safety approximation to be set for your dive, ask your diving instructor or your diving certification agency •...

  • Page 14: Limits Of Diving Computers

    Limits of diving computers The computer takes into consideration the most updated safety guide lines, nevertheless, it is always necessary to know that such studies are theoretical and elaborated to reduce, not to avoid, the risk of Decompression Sickness (DCS). At the moment, the Hyperbaric Medicine doesn’t allow to eliminate totally the risk of DD.
  • Page 15 The EC laws require that the unit is checked periodically from the reading precision, depth and time point of view. • Warranty is voided 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 16: 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 developing a navigation system allowing the diver to have an easy and intuitive access to all settings.

  • Page 17: Software

    Software Algorithm: The computer uses either the Bühlmann ZHL-16B model or the VPM-B model. Every computer can be set up on one algorithm or the other, at the user’s discretion. For RATIO iX3M Deep: Operating on level systems it is possible to set up the conservatism desired. For RATIO iX3M Tech+ and iX3M Reb: Using the Bühlmann ZHL-16B algorithm there is the possibility of an exact choice of the Gradient Factors.

  • Page 19: How To Recharge The Battery

    How to recharge the Battery The RATIO iX3M has a Li-Ion rechargeable battery without memory effect, with an autonomy of 20-50 diving hours. The autonomy data which are shown can change of +/- 15% depending on the environmental temperature, the device settings, the installed applications, the operative system version, the back light setting and the use of its inner (GPS - Bluetooth)or external (Analyser) peripheral devices.
  • Page 20 When connecting the USB cable to recharge the device, the symbol => will appear in the watch screen within 45 seconds. It means that recharging procedure is in progress. When the recharge is finished the symbol => will disappear. Once the battery charge is finished, even if the device remains connected to the plug, the computer automatically interrupts the electricity flow.

  • Page 21: 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 affect 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.

    The RATIO iX3M outside the Water: The main screen To switch the RATIO iX3M on, press any button. 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 24 First line: In the first line of the introductory screen the RATIO iX3M shows: - Battery indicator (on the top left side) the RATIOiX3M uses a colour code to advise you on its battery status Green colour (100%->50%): Everything is ok Yellow colour (50%->20%): Alert (do not make extremely demanding dives or in cold or freezing waters) Red colour (<20%): Battery almost dead, recharge as soon as possible.
  • Page 25 Second line: - Atmospheric Pressure expressed in millibar (on the left) The Atmospheric pressure is the one present in any point of the terrestrial atmosphere. It is measured in millibar (mbar) Attention: after diving, owing to the humidity on the sensor’s location, the read pressure might be slightly lower than the real one.
  • Page 26 Third line: - Barometric alitmeter (on the left) The height above the sea level is calculated on the basis of the barometric pressure. Attention: The altitude detection through the barometer can be affected by the presence of humidity in the sensor area. In case of case of bad weather or after diving, the error might also be of +/-80m.
