ALADIN ONE USER MANUAL
3.2.2 Alarms
Alarms are provided visually by flashing
symbols, letters or figures. In addition, an
audible sequence in one frequency can be
heard during the whole duration of the alarm.
An alarm occurs in the following situations:
• Oxygen toxicity reaches 100%.
• Ignored decompression.
• Exceeding the prescribed ascent rate.
• Altitude alarm.
• Low battery alarm (without audible
alarm): battery icon appears if battery
has to be replaced.
F
NOTE: Audible attention messages
can be switched off in the watch
settings mode (by pressing the right
button 5x to the sounds screen) or
in LogTRAK. With LogTRAK sounds
can be switched off selectively or
completely
.
WARNING
If you turn off all sound you will have no
audible warnings. Without audible warnings
you could inadvertently find yourself in
potentially hazardous situations which could
result in death or serious injury.
WARNING
Serious injury or death may result from failing
to immediately respond to alarms provided by
the Aladin One.
3.3 Preparation for the dive
It’s important to check the settings of the
Aladin One, especially before the first dive.
All settings can be checked and changed
directly on the Aladin One or by using
LogTRAK and a PC.

the Aladin One with the right button the test
display will not appear.)

dive. See chapter:
System and Operation ,
