4.1 Immersion
After immersion, starting at a depth of about 0.8 m (3 ft), all diving functions are monitored, i.e. depth and
dive time displayed, maximum depth stored, saturation of tissues calculated, no-stop time or decompres-
sion prognosis determined, ascent rate controlled and displayed and the correctness of the decompression
procedure supervised.
4.2 Phosphorescent display
Aladin
®
ONE
is equipped with a phosphorescent display. To excite the phosphorescence, shine your dive
torch onto the display for a few seconds. The display will glow for about one minute depending on the
strength of your dive torch and how close it was held to the display.
4.3 Dive time
The whole time spent below a depth of 0.8m (3 feet) is displayed as dive time
in minutes. The time above 0.8m (3 feet) is counted as dive time only if the
diver descends again below 0.8m (3 feet) within 5 minutes.
While the dive time is running, the colons on the right of the figures are flash-
ing in one second intervals. Maximum dive time displayed is 199 minutes.
If a dive lasts longer than 199 minutes the dive time display starts
again at 0 minutes.
4.4 Current depth / O
2
% mix
Current depth is given in 10 cm increments (1 foot).
At a diving depth of less than 0.8 m (3 ft) the display shows
"– – –".
The O
2
% mix is diplayed as long as CNS O
2
% = 0 and no ascent speed is
indicated.
Depth measurement is based on salt water. Therefore, Aladin
®
ONE
shows a slightly shallower depth than actual when diving in fresh
water. No calculation however is affected.

4.5 Maximum depth / Temperature
In the lower left corner of the screen Aladin

displays the water tempera-
ture and the maximum depth alternating every 4 seconds.
Maximum depth is only displayed if it exceeds the current depth by more than
1 m (3 feet) (maximum depth indicator function).
