Section 2: Diving with the Monitor 3 Air

Microbubble Warning

Repetitive diving may cause microbubbles to accumulate in the lungs if the surface interval between dives is not long enough. Ignoring decompression stops or an excessive ascent rate can also lead to bubble formation. In order to reduce the risk of decompression sickness for future repetitive dives, the surface interval should be planned long enough to reduce the risk of decompression sickness. If the Monitor 3 Air calculates that the forma- tion of microbubbles may occur during the surface interval, it will advise the diver to extend the surface interval. The display “Atn” (= attention) is visible in the depth display area during the surface mode. While “Atn” is displayed, the diver should not undertake another dive.

Note: If a dive has to be made while “Atn” is displayed, the amount of “Atn”-time for the following dive can increase considerably. During the dive, no-stop times will be much shorter and decompression times will increase.
