5.1 End of a dive
After reaching the surface (<0.8 m/3 ft) TEC remains in dive mode for 5 minutes.
The delay allows for surfacing for a short period for orientation.
After 5 minutes the dive is closed and it is entered into the logbook.
For the calculations of the desaturation and no-fly time it is assumed that the
diver breathes air while on the surface.
5.2 Desaturation time
After the dive has been closed
,
desaturation time in hours and
minutes and, if available, oxygen toxicity is displayed. Desaturation time is
determined either by oxygen toxicity, nitrogen saturation or the regression of
microbubbles, depending on which requires the longer time. Oxygen toxicity
(<CNS O
2
>) is displayed and adjusted until the value becomes 0%.
Desaturation time is indicated until the next dive or until it reaches zero.
The display is switched off to save energy three minutes after the last manipu-
lation is made. The calculations are nevertheless continued in the background.
5.3 No-fly time
The <no-fly time> is indicated beside the icon <do not fly>. <No-fly time> is the
time in hours that should pass before a flight and is displayed and adjusted until
the value becomes 0 hours.
Flying while TEC displays <do not fly> may lead to
serious injury or death from decompression sickn-
ess.

5.4 Microbubble warning
Through repetitive dives microbubbles accumulate in the lungs if the surface
interval is not long enough. Ignoring decompression stops or ascending at an
excessive rate can also lead to microbubbles in tissues. In order to reduce the
risk of decompression sickness for repetitive dives, the surface interval should
be planned long enough. If TEC calculates that the formation of microbubbles
occurs during the surface interval, it will advise a diver to extend the surface
interval via the microbubble warning. The duration of the microbubble war-
ning is visible by entering the dive planner -> 37.
If the <microbubble warning (NO DIVE)> is visible
during the surface interval, the diver should not
undertake another dive.
If the dive is made in spite of the microbubble warning, the diver must cope
with a clearly shorter no-stop time or an extension of decompression. Also, the
duration of the microbubble warning at the end of the dive can increase con-
siderably.
