ALADIN SQUARE USER MANUAL
WARNING:
represent situations that require the diver’s
attention, but ignoring them does not represent
an immediate risk. It is up to you to decide
which ones you would like to be active and
which ones not. The available warnings are:
2.6.1 CNS O
2
= 75%
Square tracks your oxygen uptake via the
CNS O
2
clock. If the calculated value of
CNS O
2
reaches 75%, Square will emit a
sequence of audible beeps for 12 seconds
and the value of the CNS O
2
will be blinking
in the lower right corner. The blinking will
continue until the value of CNS O
2
drops
under 75%.
2.6.2 No-Stop time = 2 minutes
If you wish to avoid unintentionally
performing a decompression dive, Square
can activate a warning when the no-stop
time reaches 2 minutes. This applies to
both L0 no-stop and MB no-stop time
(see chapter Diving with MB levels for more
information on MB level diving). It gives you
the opportunity to start ascending before
incurring a decompression stop or a level
stop obligation.
Square emits a sequence of audible beeps
for 12 seconds and the no-stop time will
blink. The blinking will continue until you
ascend suffi ciently for the no-stop time to
grow to 3 minutes, or until Square enters
into decompression.
2.6.3 Entering decompression
Square can activate a warning when
the fi rst mandatory decompression stop
appears. This alerts the diver to the fact
that a direct ascent to the surface is no
longer possible. This warning applies to
dives with the computer set to L0 only.
Square emits a sequence of audible beeps
and the DECO STOP symbol blinks, both
for 12 seconds, when the no-stop time
ends and a mandatory (L0) stop is required
before reaching the surface.
2.6.4 Entering level stops
When diving with a microbubble (MB) level
different than L0, Square can warn you
when you are no longer in the MB no-stop
phase. See section 2.7.5 Diving with MB-
Levels for more information on MB level
diving.
Square emits a sequence of audible beeps
and the STOP symbol blinks, both for 12
seconds, when the MB no-stop time ends
and a level stop is required before you
ascend to the surface.
