3.4.6

Set max depth reached

If the set max depth has been reached (default
40m/130ft) and the depth alarm is turned on,
the alarm tone sounds and the depth display
flashes. Ascend until the depth stops flashing.
3.4.7 RBT 3 minutes and 0 minutes
reached
The RBT (Remaining Bottom Time) is the
time you can spend at the current depth
and still have enough gas supply to make
a safe ascent and reach the surface with
the tank reserve. The RBT calculation is
based on your current breathing rate, and
it accounts for any existing and upcoming
decompression obligation as well as for
any temperature gradient in the water. It
assumes an ascent at the ideal ascent rate
(defined in chapter: Diving with your Aladin
H, section: Ascent rate).

WARNING
WARNING
When the RBT of 0 minutes has been reached,
the alarm tone sounds and the 0: flashes. Start
your ascent – any further delay increases the
risk that you will run out of gas supply before
reaching the surface.
3.4.8 Half and reserve tank
pressures reached
When the set half tank pressure has been
reached the warning tone sounds.
When the reserve tank pressure value has
been reached, the tank pressure value
flashes and alarm tone sounds until you
reach the surface.
