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.
• The diving computer DOES NOT replace an adequate diving training and should be used only by those divers who have
been opportunely trained.
• The RATIO® computer is an auxiliary instrument to the dive, so it is compulsory having always an appropriate diving chart
in order to carry out the decompression phase in case the device is malfunctioning.
• Diving involves risks relating to decompression sickness, Oxygen toxicity and other risks relating to the diving itself. Even
a careful reading of this manual and the use of this device don’t prevent possible dangers. Anyone who doesn’t know or
doesn’t accept consciously these risks, must not dive with iX3M computer.
• Diving has some intrinsic risks which cannot never be completely eliminated.
No computer or diving chart can guarantee that the risk of Decompression Sickness (DCS) or Oxygen toxicity to the central
nervous system don’t exist, even if the diver follows meticulously and accurately the indications given by the computer or
the diving chart.
• The computer cannot take into consideration the individual physiological variations which might change day by day. For
this reason it is good practice to use the device in a conservative and preventive way, remaining within the limits indicated
by the computer, to minimize the risks of DD and Oxygen toxicity to the central nervous system.

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.
• Never dive with a computer which has not taken into consideration the previous dives a diver made; the computer
calculation CANNOT use unknown data or take into consideration dives which it has not done.
