ALADIN H USER MANUAL
Functions during a dive with 2 or 3 gas
mixtures
WARNING
Diving with 2 or 3 gas mixtures represents
a much higher risk than diving with a single
mixture, and mistakes by the diver may lead to
serious injury or death.
During dives with several gas mixtures,
always make sure you are breathing from
the tank you intended to breath from. Mark
all your tanks and regulators so they can
under no circumstances be mixed up!
Before every dive and after changing a
tank, make sure that each gas mixture is set
to the correct value for the corresponding
tank.
Predictive decompression prognosis
The calculation of decompression data is
based on the assumption that the change(s)
of gas mixture(s) will be performed at the
previously selected switch depth(s) (MOD
gas 2/gas d). If you ignore a required
change or change the mixture belatedly, the
Aladin H will readjust the decompression
calculation accordingly. In case of an
ignored switch the dive computer will then
base its calculations on the assumption
that you will ascend to the surface without
using the proposed gas.
Alternate displays during a dive with
2 gases
1. The default display shows the predictive
decompression prognosis, which
assumes the diver will switch to the deco
gas at the specified switch depth. In
the bottom left corner the tank pressure
is displayed with O
2
% or CNS% when
higher than 50% at the right corner.
2. Upon pressing the right button, the
temperature and the current CNS%
are shown in the lower row. CNS%
will time out after 5 seconds while the
temperature remains.
3. Upon pressing the right button, “GAS
1”, “GAS 2” or “GAS d” appears in the
middle row to indicate the currently
active gas, and the MOD appears in the
bottom left corner. “GAS 1”, “GAS 2” or
“GAS d” will time out after 5 seconds
unless the right button is pressed again.
4. Pressing the right button one more
time shows the O
2
% of the active gas
in the bottom right corner and the
decompression information in case the
dive would be finished with the currently
active gas (no switch to gas 2/deco gas).
This is the calculation that the Aladin H
would switch to in case, having reached
the switch depth(s), the diver did not
confirm the switch(es). The decompression
information and the O
2
% blink.
5. If an MB level greater than L0 is active,
pressing the right button one more time
shows the predictive decompression
information and, in the bottom left
corner, the currently active MB level.
6. Pressing the right button again
shows the predictive decompression
information relative to L0 together with
the L0 symbol at the bottom left.
7. One more right button push shows the
decompression information relative to
L0 if only the current gas is used, with
the decompression information and the
O
2
% of the current gas blinking.
8. Upon pressing the right button again, the
time of day appears in the middle row.
F
NOTE: All displays time out after 5
seconds and the default display is
shown again. The only exceptions are
tank pressure, RBT with 15 seconds,
Compass with an adjustable time out
from 5 to 60 seconds or push on/off.
Changing the gas mixture

NOTE: After immersion, the Aladin H
automatically selects gas 1.
