display will be replaced by an ASC TIME no-
tation and the maximum depth will be re-
placed by a CEILING notation and an upward
pointing arrow (Fig. 3.16.).
If you exceed the no-decompression limits on
a dive, the dive computer will provide decom-
pression information required for ascent. After
this, the instrument will continue to provide
subsequent interval and repetitive dive infor-
mation.
Rather than requiring you to make stops at
fixed depths, the dive computer lets you to
decompress within a range of depths (Con-
tinuous Decompression).
The ascent time (ASC TIME) is the minimum
amount of time needed to reach the surface
in a decompression dive. It includes:
the time needed to ascend to the
ceiling at an ascent rate of
10 m/min [33 ft/min]
plus
the time needed at the ceiling. The
ceiling is the shallowest depth to
which you should ascend
plus
the time needed at the Mandatory
Safety Stop (if any)
plus
the 3 minute Recommended Safety
Stop
plus
the time needed to reach the surface
after the ceiling and safety stops have
been completed.
Fig. 3.13. Ascent Rate
Indicator. Blinking depth
reading, SLOW and four
segments are shown
together with an audible
alarm: ascent rate is more
than 10 m/min [33 ft/min].
This is a caution to slow
down! STOP sign means
that you are advised to
make a Mandatory Safety
Stop when you reach a
depth of 6 m [20 ft].
