Operation Manual

4.8 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.
* 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 6th segment will turn off as soon as you complete your last
decompression obligation to indicate that you are no longer in decompression.
4.9 Decompression information
NO STOP and the no-stop time (minutes) are displayed if no decompression stops are necessary.
• No-stop display "99:" means remaining time of 99 minutes or
more.
• No-stop time is influenced by the water temperature.
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.

Decompression values On entering the decompression phase, "NO STOP" disappears, the
STOP
DECO
sym-
bol appears and an attention beep goes off. The nitrogen loading bar stops
flashing 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 completed, the next (shallower) decom-
pression stop is displayed. When all decompression stops have been com-
pleted, the
STOP
DECO
symbol extinguishes, "NO STOP" and no-stop time reappear.
Deco stop depths deeper than 27m (90ft) are displayed as " – – : – – ".

1-3 segments
(green area):
you are safely
within the no-stop
range.
4-5 segments (yellow area):
you are approaching decom-
pression. When the no-stop
time drops below 3 minutes the
5 segments will start
flashing.*
6 segments (red area): you now
have mandatory decompression
obligation(s) which you must
observe before reaching the
surface.
