ascents, yo-yo dives, skipping mandatory decompression
stops, dives with surface intervals that are too close together,
and any other behavior that goes against common sense or
your training.

Failure to observe the basic rules of scuba diving expose the diver
to life-threatening risk.
We recommend dives within the safety curve in order to reduce
the risks associated with decompression sickness.
• We recommend dives of no deeper than 40 meters, or
depending on the percentage of oxygen in the tank, ppO
2
max
1.4 BAR. Exposure to higher values puts the diver's life in
danger.
• Abide by the ascent rate recommended by the computer.
Excessive ascent speeds put the diver's life at risk.
• The computer calculates the total ascent time, but this
could be longer than the time shown depending on certain
parameters that the computer calculates throughout the
dive. Trying to ascend at the correct speed and abiding by
the depths of the stops shown will help respect this duration.
• Always respect the NO FLY time: absolutely do not board
an airplane if the NO FLY icon is still shown on the display.
Remember to plan your last dive in the series keeping in
mind the recommendations provided by DAN (Divers Alert
Network).
• Even if you abide by all the intervals dictated by hyperbaric
medicine, the occurrence of decompression sickness on
board a plane cannot be excluded after dives.
Dives with Nitrox mixtures.
When setting the gas fraction in the tank, the computer will only
acceptwholenumbers,sointhecaseofaveriedgasfraction
of 32.8, the next lower whole number must be set, and thus 32
in this case.
Do not round up to the next higher number because this would
underestimate the nitrogen calculations.
• Check the ppO

max setting, and never exceed 1.4 BAR.

dive without the appropriate training.
• Exceeding the maximum recommended ppO
2
limit set dictates
an ascent to lower levels, and in the case of a CNS (Central
Nervous System) value approaching the limit, reduced
exposure to oxygen is recommended.
• Only use the dive computer after you have read all sections of
the instruction manual and you have understood how it works.
If you have any doubts or questions, contact your instructor or
dealer before you dive.
Before the dive
• It is crucial to understand that every diver is completely
responsible for their own safety.
• Dives using gas mixtures entail risks other than those
associated with dives using standard air. Adequate training
is necessary in order to learn to understand and avoid these
risks, which are not immediately obvious. These risks include
serious injury or death.
