DISPLAY ABOVE THE FLOOR
When you ascend above the fl oor, the ASC TIME display
stops blinking and the upward pointing arrow disappears (Fig.
6.11.). Decompression will now begin, but is very slow. You
should therefore continue your ascent.
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
6.12.). Do not ascend above this zone.
During the decompression stop, ASC TIME will count down
towards zero. When the ceiling moves upwards, you can as-
cend 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 completed. You are advised, however, to stay un-
til the STOP sign has also gone. This indicates that the three
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 bee-
ping starts (Fig. 6.13.). In addition, an error warning Er re-
minds you that you have only three minutes to correct the
Fig. 6.13. Decompressi-
on dive, above ceiling. No-
te downward pointing ar-
row, Er warning and an
audible alarm. You should
immediately (within 3 mi-
nutes) descend to or be-
low ceiling.
