Decompression values
On entering the decompression phase, the arrow
disappears, the
arrow
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 dis-
played stage appears in minutes. The display <3m 7:> means that a decom-
pression 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
extinguishes and the arrow
reappears. The indication of
time on the lower right shows the no-stop time again.
Deco stop depths deeper than 27m (90 ft) are displayed as <– – : – – >
The decompression alarm is activated if the
decompression stop is ignored. The arrow
, 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 massive-
ly if a decompression stop is ignored. When the surface is reached during
the decompression alarm, the arrow
, the decompression stop
duration and decompression stop 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 (->11).
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 TEC shows the total time of ascent.
This includes the ascent time from the current depth to the surface and all decom-
pression 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 TEC
detects a higher workload.
Ascent time greater than 199 minutes is displayed as <– –>.
On all dives with TEC, make a safety stop for at least
three minutes at a depth of 5 m (15 feet).

4.12 Safety stop timer
The safety stop timer displays the time span a diver should spend at the safety stop depth at the end of
the dive. The timer is activated by the diver and counts back to zero, starting with the time that was
pre-set with SmartTRAK. It can be restarted any number of times. Range: 1 - 5 minutes (default 3 min.)
The safety stop timer can be activated under the following conditions: Depth
< 6.5 m (21 ft), no-stop display 199 min., gauge mode is switched off.
Activate the safety stop timer by pressing
. The timer begins to count
backwards and a bookmark will be created in the dive profile.
The safety stop timer will switch off automatically if the depth exceeds 6.5 m
(21 ft) or the no-stop phase is shorter than 199 minutes.
