Decompression values
On entering the decompression phase, the arrow
disappears. The
arrow
appears. Right beside the arrow, the deepest decompression
stage in metres (feet) is displayed. Beside the decompression depth, the decom-
pression time of the displayed stage in minutes appears. 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 decom-
pression stop is displayed. When all decompression stops have been made, the
arrow
extinguishes and the arrow
reappears. The indi-
cation of time on the lower right shows the no-stop time again.
Messages: The decompression alarm is activated if
the decompression stop is ignored. The
arrow
, the decompression time and
decompression depth begin to flash and an acoustic
alarm is initiated. Due to the formation of micro-
bubbles decompression can increase massively if a
decompression stop is ignored. When the surface is
reached during the decompression alarm, the arrow
, the decompression time and decom-
pression 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 cor-
rective action is not taken (see page 10).
If the total (cumulative) duration of the decompres-
sion alarm is longer than a minute, it is entered in
the logbook.
Response:
Descend to the prescribed decompression depth
immediately!
Total time of ascent
As soon as decompression stops are necessary Smart shows the total time of
ascent. This includes the total ascent time from the current depth to the surface
and all decompression stop obligations.
The time of ascent is calculated on the basis of the prescribed
ascent rate and a normal workload. Total time of ascent can be sub-
ject to change if the ascent rate is not ideal (100%) or if a Smart
Com detects a higher workload.
On all dives with the Smart, make a safety stop for
at least three minutes at a depth of 5 m (15 feet).
