Nitrogen Loading Bar Graph; Decompression Information - Uwatec Aladin PRIME Operating Manual

4 Functions during the dive

4.9 Nitrogen loading bar graph

The nitrogen loading bar gives a graphical representation of how close to decompression you are. As you
absorb nitrogen during the dive, more and more segments of the bar will light up. Depending on your
depth, the segments can light up more or less rapidly.
1-3 segments
(green area):
you are safely wit-
hin the no-stop
range
** Depending on your profile, the no-stop time may drop below 3 minutes before the upper 5 segments
are lit. In this case, only those segments that are lit will flash.
If you have entered decompression, the 6
pression obligation to indicate that you are no longer in decompression.

4.10 Decompression information

NO STOP and the no-stop time (minutes) are displayed if no decompression stops are necessary.

WARNING
WARNING
On entering the decompression phase, "NO STOP" disappears, the
bol appears and an attention beep goes off. The nitrogen loading bar stops flas-
hing and the 6th segment lights up (red area). The deepest decompression
stage in metres (feet) is displayed and the decompression stop duration of the
displayed stage appears in minutes. The display <7: 3m (10ft)> means that a
decompression stop of 7 minutes at a depth of 3m (10ft) 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
symbol extinguishes, "NO STOP" and no-stop time reappear.
Deco stop depths deeper than 27m (90 ft) are displayed as <– – : – – >
If no-stop time drops below 3 minutes, an audible
attention signal is activated, the no-stop value and
the nitrogen loading bar begin to flash.
If no-stop time is less than 1 minute, the no-stop
display shows the flashing value "0".
In order to prevent a decompression dive, ascend
slowly until the no-stop time is 5 minutes or more.
Dives that require decompression stops are not
recommended.
6 segments (red area): you now
have mandatory decompression
obligation(s) which you must
observe before reaching the
surface.
