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 fl oor
(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 fl oor, 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.
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.
