2 Operation
2.3 Switching on the display
• automatically, on submerging in water or when adaptation to atmospheric
pressure is necessary;
• manually, by "bridging" the water contacts with a moistened finger.
Afterwards the display shows the time of the day, the O
2
mix and the tempera-
ture. This display is called
time of day display
.
If there is a remaining saturation from the last dive, Aladin
®
ONE
displays the
logbook information of the last dive (depth, dive time, temperature, O
2
%), the
surface interval, the "do not dive" icon (if applicable) and the residual nitrogen
loading as a bar graph ->18.
If there is a remaining saturation from a change of altitude, Aladin
®
ONE
displays
the mountain symbol, the adaption time as a bar graph and the time interval
since the change in altitude class.
Aladin
®
ONE
does not display a No-Fly time. To pre-
vent decompression sickness or death, you must
wait at least 24 hours after your last dive before
flying.
When Aladin
®
ONE
is in state of rest no information is displayed but the atmo-
spheric pressure is continuously monitored. If a change in altitude range is
detected, Aladin
®
ONE
switches on for 3 minutes automatically ->20.
2.4 Switching off the display
On the surface Aladin
®
ONE
switches off automatically after 3 minutes without
operation.

2.5 Battery warning and battery alarm
When the computer senses that the battery needs to be replaced, the steady
battery symbol appears at first (warning). This allows you to do some more
dives, but you should change the battery as soon as possible.
When the battery reaches a dangerously low level, the battery symbol starts
to blink (alarm).
• Risk of computer malfunction!
The battery symbol blinks, on the surface and in
dive mode, to alert the diver of a dangerous situ-
ation: the battery may not have enough energy
to finish a dive.
Do not dive or finish the dive and replace the
battery ->21.
• Replace the battery when the steady battery
symbol appears ->21!
The battery condition can be checked with SmartTRAK.
The temperature influences the battery performance. In cold water it is lower
than in warm water. If the battery shows the steady battery symbol on the
surface, it is possible for it to start flashing during the dive.
