Total Ascent Time; Safety Stop Timer; Functions After The Dive; End Of A Dive - Uwatec Aladin ONE Matrix User Manual

The decompression alarm is activated if the
decompression stop is ignored. The "DECO
STOP" arrow, the decompression stop duration,
and the decompression stop depth begin to
flash and an audible alarm sounds. Due to the
formation of microbubbles, decompression
can increase massively if a decompression
stop is ignored. Descend to the prescribed
decompression stop depth immediately!
When the surface is reached during the
decompression alarm, the "DECO STOP"
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. If the total
(cumulative) duration of the decompression
alarm is longer than one minute, it is
entered in the logbook.

Total ascent time

As soon as decompression stops are
necessary, the Aladin One shows the total
time of ascent. This includes the ascent time
from the current depth to the surface as well
as all decompression stop obligations.
F
NOTE: The total time of ascent
is calculated on the basis of the
prescribed ascent rate. Total time of
ascent can be subject to change if
the ascent rate is not ideal (100%).
Ascent time greater than 99 minutes
is displayed as " – – ".
On all dives with the Aladin One, make a safety
stop for at least 3 minutes at a depth of 5m/15ft.

Safety stop timer

Safety stop time (minutes, seconds)
Safety Stop Icon
The safety stop timer displays the time a
diver should spend at the safety stop depth
at the end of the dive. The timer starts
automatically when depth is shallower than
5m/15ft and counts back from 3 minutes
(default) to zero. It can be restarted manually
any number of times. The duration of the
timer can be set between 1 and 5 minutes.
The safety stop timer will be activated
under the following conditions: depth
<5m/15ft; no-stop display of 99 min; stop
time is selected (1-5 min) in the scuba
mode menu.
You can activate the safety stop timer by
pressing the left button. The timer begins
to count backwards. If you press again, the
timer will start again from the full value.
The safety stop timer will switch off
automatically if the
6.5m/21ft or the no-stop phase is shorter
than 99 minutes.
