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 perma-
nent Error Mode. The instrument will continue to function normally if you descend be-
low the ceiling within this three-minute period.
Once in the permanent Error Mode only the ER warning is shown in the center win-
dow. The dive computer will not show times for ascent or stops. However, all the ot-
her displays will function as before to provide information for ascent. You should im-
mediately 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 Mo-
de will be disabled.
