3.9. ERROR CONDITIONS
The dive computer has warning indicators that alert the user 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 and operate the dive computer sensibly, it is very unlikely
you will ever put the instrument into the Error Mode.
OMITTED DECOMPRESSION
The Error Mode results from omitted decompression, i.e. 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 will enter a permanent Error Mode. The
instrument will continue to function normally if you descend below the
ceiling within this three-minute period.
Once in the permanent Error Mode only the ER warning is shown in the
center window. The dive computer will not show times for ascent or
stops. However, all the other displays will function as before to provide
information for ascent. You should immediately ascend to a depth of 3
to 6 m [10 to 20 ft] and remain at this depth until air supply limitations
require you to surface.
After surfacing, you should not dive for a minimum of 48 hours. During
the permanent Error Mode, the Er text will be displayed in the center
window and the Planning Mode will be disabled.
