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.
5.7. 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.
Descent at the rate of 10 m/min is included in the time. The times allow for a safe ascent
using the bottom gas all the way to the surface without exceeding tissue pressures.
Omitted decompression
The Error mode results from omitted decompression, for example, when you stay
above the ceiling for more than three minutes. During this three-minute period the Er
warning is shown and the audible alarm beeps. After this, the dive computer enters a
permanent Error mode. The instrument will continue to function normally if you descend
below the ceiling within this three-minute period.
