Important Warnings
General Warnings
It is necessary to read this manual carefully before using the computer RATIO®. Wrongful 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 backup
(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 won’t prevent possible dangers. Anyone who doesn’t know or
doesn’t accept consciously these risks, must not dive with iX3M 2 computer.
• Diving has intrinsic risks which cannot be completely eliminated.
No computer or diving chart can remove the risk of Decompression Sickness (DCS) or Oxygen toxicity to the cSELECTl
nervous system, even if the diver meticulously and accurately follows 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 cSELECTl nervous system.

• 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.

10
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). For this reason we discourage its use in case of professional or commercial dives, unless it is
used as an operator’s further support device.
• Before diving it is necessary to check the battery autonomy. DO NOT dive if the battery level is at 30% or at lower
percentages; make sure that the screen doesn’t show malfunctioning signs. It must be read clearly.
• Check always that settings are the ones desired. Don’t let the computer be manipulated by someone else before diving. In
this case, check that settings are the ones you desire.
• Consider that our body experience changes everyday. The computer cannot take into consideration all these changes. If
you don’t feel at your best physical conditions or if you feel physical problems, don’t dive.
• Avoid all behaviors increasing the risks connected to the DD such as rapid ascents, yo-yo dives, violation of compulsory
decompressive stops, dives with too close surface intervals and any behavior which is contrary to the common sense and
to the training received.
• This device doesn’t allow its use without having the due skill, given by a specic training.
The failure to comply with the basic rules of diving exposes the diver at death danger.
