ALADIN SQUARE USER MANUAL
In case you have done a dive and you
plan to make another dive during the
desaturation phase, you must start a plan
by giving the time you would still stay at the
surface.
By pressing the right or left you can step
the time in 15 minutes steps.
In case Square is displaying the no-dive
warning, the duration of the warning itself is
displayed as recommended surface interval
for planning purposes (rounded up to the
nearest fi fteen-minute increment).
When surface interval is given or if you
have no remaining desaturation left, the
planner depth value starts blinking. By
pressing right or left you can set the depth
in 3m/10feet steps.
The no decompression dive time is shown
for that depth at the top row right.
Minimum depth for planning is 9m/30feet.
The planner allows only depths according
to maximum ppO
2
given to the GAS1. If
GAS1 MOD is shallower than 9m/30feet,
planning is not allowed and information LO
ppO
2
is shown.
The gas oxygen content and maximum
ppO
2
settings are given at the dive mode
menu: SET GAS.
WARNING
If you have set ppO
2
max to OFF, the planner will
allow depths up to maximum of 120m/394ft.
Air/nitrox dives with high ppO
2
are extremely
dangerous and can lead to death. Be aware that
exposures to high ppO
2
will lead CNS clock value to
exceed maximum recommended 100%.

NOTE: The dive planner considers all
programmed gas mixtures to be used
at the planned dive when computing no-
stop times or decompression schedules.
By pressing SEL for planned depth the dive time
appears at bottom row. Start point (minimum now)
is the no decompression time. By pressing right or
left you may change the time in 1 minute steps.
When no decompression time is exceeded the
planner gives the deepest decompression depth
and time on top of the black DECO STOP symbol.
MB level stops (if selected) are shown at the same
place just with symbol STOP. Total Ascent Time
(TAT) is shown at the middle right. Total Ascend
Time (TAT) is shown at the middle right.
If the plan reaches CNS clock limit of 75%
the symbols CNS O
2
% starts blinking and
replaces the TAT value at middle right.
By pressing SEL or ESC the planner will exit
and you will get to the main menu.
