lift you above the ceiling. Suunto recommends that decompression takes place deeper than 4 m [13 ft], even if the indicated ceiling is shallower.
NOTE! It will take more time and more air to decompress below the ceil- ing than at the ceiling.
WARNING!
NEVER ASCEND ABOVE THE CEILING! You must not ascend above the ceiling during your decompression. In order to avoid doing so by accident, you should stay somewhat below the ceiling.
DISPLAY BELOW THE FLOOR
The blinking ASC TIME and an upward point- ing arrow indicate that you are below the floor (Fig. 3.16.). You should start your ascent im- mediately. The ceiling depth is shown on the right top corner and the minimum total ascent time on the right side of the center window.
DISPLAY ABOVE THE FLOOR
When you ascend above the floor, the ASC TIME display stops blinking and the upward pointing arrow disappears (Fig. 3.17.). Decom- pression will now begin, but is very slow. You should therefore continue your ascent.

Fig. 3.15. Violated Mandatory Safety Stop. Downward pointing arrow and an audible alarm indi- cate you should descend to ceiling zone.
DISPLAY AT THE CEILING ZONE
When you reach the ceiling zone, the display will show you two arrows pointing at each other (the “hour glass” icon, Fig 3.18.). Do not as- cend above this zone.
During the decompression stop, ASC TIME will count down towards zero. When the ceiling moves upwards, you can ascend to the new ceiling. You may surface only after the ASC TIME and CEILING labels have disappeared, which means that the decompression stop and any Mandatory Safety Stop has been complet- ed. You are advised, however, to stay until the STOP sign has also gone. This indicates that the three minute Recommended Safety Stop has also been completed.
