SUUNTO D4i - Manual (Page 15)

WARNING
WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE
MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY
TAKE ACTION TO REDUCE OXYGEN EXPOSURE. Failure to
take action to reduce oxygen exposure after the warning is given
can rapidly increase the risk of oxygen toxicity, injury, or death
WARNING
Suunto recommends that you receive training in Free diving
techniques and physiology before conducting breath hold dives.
No dive computer can replace the need for proper dive training.
Insufficient or improper training may cause a diver to commit errors
that may lead to serious injury or death.
WARNING
If there are several divers using the dive computer with wireless
transmission, always ensure that each diver is using a different
code before starting the dive.
WARNING
Using the Suunto Dive Planner software is not a substitute for
proper dive training. Diving with mixed gases has dangers that
are not familiar to divers diving with air. To dive with trimix, triox,
heliox and nitrox or all of them, divers must have specialized
training for the type of diving they are doing.
