3.8. ERROR CONDITIONS
The dive computer has w arning indicators that alert the user to react to certain
situations that would signifi cantly 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 di ve computer sen-
sibly, 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 w arning 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 per-
manent Error Mode, the Er te xt will be displayed in the center windo w and the
Planning Mode will be disabled.
