Decompression values On entering the decompression phase, the arrow
NO STOP
disappears, the
arrow
DECOSTOP
appears and an attention beep goes off. Right beside the
arrow, the deepest decompression stage in metres (feet) is displayed. Next to the
decompression stop depth, the decompression stop duration of the displayed
stage appears in minutes. The display <3m 7:> means that a decompression
stop of 7 minutes at a depth of 3m has to be made. When a decompression
stop has been finished, the next higher decompression stop is displayed. When
all decompression stops have been made, the arrow
DECOSTOP
extinguishes
and the arrow
NO STOP
reappears. The indication of time on the lower right
shows the no-stop time again.
The decompression alarm is activated if the decom
-
pression stop is ignored. The arrow
DECOSTOP
, the
decompression stop duration and decompression
stop depth begin to flash and an audible alarm
goes off.
Due to the formation of microbubbles, decompression can increase mas
-
sively if a decompression stop is ignored. When the surface is reached during
the decompression alarm, the arrow
DECOSTOP
, the decompression stop
duration and decompression
depth continue flashing, in order to point to
the risk of a decompression accident. The SOS mode is activated 3 minutes
after the dive if corrective action is not taken (-> 10).
If the total (cumulative) duration of the decompression alarm is longer than
one minute, it is entered in the logbook.
Descend to the prescribed decompression stop depth immediately!
Total time of ascent
As soon as decompression stops are necessary Smart shows the total time of
ascent. This includes the ascent time from the current depth to the surface and
all decompression stop obligations.
The total time of ascent is calculated on the basis of the prescribed
ascent rate and a normal workload. Total time of ascent can be
subject to change if the ascent rate is not ideal (100%) or if Smart
COM detects a higher workload.
On all dives with Smart, make a safety stop for at
least three minutes at a depth of 5 m (15 feet).
