NOTE! It will take more time and more air to decompress below the
ceiling than at the ceiling.
WARNING!
NEVER ASCEND ABOVE THE CEILING! You must not ascend
above the ceiling during your decompression. In order to avoid do-
ing so by accident, you should stay somewhat below the ceiling.
DISPLAY BELOW THE FLOOR
The blinking ASC TIME and an upward
pointing arrow indicate that you are below the
floor (Fig. 3.16.). You should start your ascent
immediately. The ceiling depth is shown on
the right top corner and the minimum total
ascent time on the right side of the center win-
dow.
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.). De-
compression 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 oth-
er (the “hour glass” icon, Fig 3.18.). Do not
ascend above this zone.
During the decompression stop, ASC TIME
will count down towards zero. When the ceil-
ing moves upwards, you can ascend to the
new ceiling. You may surface only after the
ASC TIME and CEILING labels have disap-
peared, which means that the decompression
stop and any Mandatory Safety Stop has been
completed. You are advised, however, to stay
until the STOP sign has also gone. This indi-
cates that the three minute Recommended
Safety Stop has also been completed.
