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.
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.
Serious injury or death may result from failing
to immediately respond to alarms provided by
the Aladin One.

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

LogTRAK and a PC.
