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.
5.6. Error conditions
The dive computer has warning indicators that alert you to react to certain situations
that would significantly increase the risk of DCI. If you do not respond to its warnings,
the dive computer will enter an Error mode, indicating that the risk of DCI has greatly
increased. If you understand the dive computer and operate it sensibly, it is very unlikely
you will ever put the instrument into the Error mode.
