Performing a Decompression Stop
You should always perform all the required decompression stops during a dive to help reduce the risk of
decompression sickness. Missing a decompression stop adds significant risk.
1 When you exceed the no-decompression limit (NDL) time, begin your ascent.
Decompression stop information appears on the data screens.
Your depth relative to the surface.
As you ascend, your position moves upward toward the required decompression stop depth. The
empty segments represent cleared stops. You may clear a stop before ascending to it.
The decompression stop ceiling depth.
The decompression stop timer.
2 Stay within 0.6 m (2 ft.) of the decompression stop ceiling depth until the decompression stop timer reaches
zero.
NOTE: If you ascend more than 0.6 m (2 ft.) above the decompression stop ceiling depth, the decompression
stop timer pauses, and the device alerts you to descend below the ceiling depth. The depth and ceiling depth
flash until you are within the safe margin.
3 Continue ascending to the surface or the next decompression stop.
Viewing the Surface Interval Glance
1 From the watch face, press UP or DOWN to view the surface interval glance.
2 Press START to view your oxygen toxicity units (OTU) and central nervous system (CNS) percentage.
NOTE: The OTU accumulated during a dive expire after 24 hours.
3 Press DOWN to view your tissue load details.
4 Press DOWN to view your no-fly time remaining and the time of day the no-fly period ends.
