When conditions are rough, it may be diffi cult to
maintain a constant depth near the surface. In this
case it will be more manageable to maintain an
additional distance below the ceiling, to make sure
that the waves do not 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 gas 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 doing so by
accident, you should stay somewhat below the
ceiling.
Fig. 3.17. Decompression dive,
below fl oor. Upward pointing
arrow, blinking ASC TIME
label and an audible alarm tell
you to ascend. Minimum total
ascent time including safety
stop is 7 minutes. Ceiling is at
3 m [10 ft].

Upward pointing arrow has disappeared and
ASC TIME label has stopped blinking, which
means that you are in the decompression range.
