SUUNTO D9tx - Manual (Page 48)

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.
When the dive computer is in the permanent Error mode, only the Er warning is shown
in the center window. The dive computer does not show times for ascent or stops.
However, all the other displays function as before to provide information for ascent.
You must 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 is displayed in the center window and the planning mode is
disabled.
