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.
• In any event, the instrument may not be used without sufficient
preparation earned through specific 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
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.
• Check the ppO max setting, and never exceed 1.4 BAR.

• NEVER DIVE without first checking the contents of the tanks
with instruments that have been declared reliable.
• Check that the gas set on the computer corresponds to what
is in the tank you'll be diving with.
• Dives with Nitrox-Trimix-CCR require specific training. DO NOT
dive without the appropriate training.
• Exceeding the maximum recommended ppO
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.
• It is crucial to understand that all divers are fully 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.
Limits of dive computers
The computer reflects the most up-to-date guidelines on dive
safety, but it must be stressed that the studies should be
considered theoretical. Their aim is to reduce risk, but they
cannot prevent the possibility of contracting illnesses associated
with underwater activities: decompression sickness when scuba
diving, and syncope/taravana/hemoptysis when freediving.
