Figure 6.9. Decompression dive, at ceiling zone. Two arrows point at each other (“hour
glass”). You are in the optimum ceiling zone at 3.5 m/11 ft and your minimum ascent
time is 5 minutes. Pressing TIME button activates alternative display.
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 decom-
pression stop and any Mandatory Safety Stop have been completed. You are advised,
however, to stay until the STOP sign has also disappeared. This indicates that the
three (3) minute Recommended Safety Stop has also been completed.
Display above the ceiling
If you ascend above the ceiling during a decompression stop, a downward pointing
arrow will appear and a continuous beeping starts.
