If the ascent rate is greater than 110% of
the ideal value the SLOW symbol appears.
For ascent rates higher than 140%, the
SLOW symbol starts to blink.
Square also provides an audible alarm in
case of ascent rates exceeding 110%: the
intensity of the alarm increases in direct
proportion to the degree that the ideal
ascent rate is exceeded.
In case of a fast ascent, Square may
require a decompression stop even within
the no-stop phase because of the danger
of microbubble formation.
From great depth a slow ascent may
cause heightened saturation of tissues
and an extension of both decompression
duration and total ascent time. At shallow
depth, a slow ascent may shorten the
decompression duration.
Excessive ascent rates for longer periods
are entered in the logbook.
WARNING:
The ideal ascent rate must not be exceeded at
any time since this could lead to microbubbles
in the arterial circulation which could cause
serious injury or death.
The alarm persists for as long as the ascent
rate is 110% or more of the ideal ascent rate.
2.6.8 MOD/ppO
2
WARNING:
- The MOD should not be exceeded.
Disregarding the alarm can lead to oxygen
poisoning.
- Exceeding a pp O
2
of 1.6bar can lead to
sudden convulsions resulting in serious injury
or death.
If you exceed the MOD, the depth will start
to blink and in the bottom row the MOD is
displayed so you can see by how much you
have exceeded it. In addition, Square will
beep incessantly. Both the blinking of the
depth value and the beeping will continue for
as long as you stay deeper than the MOD.
2.6.9 CNS O
2
= 100%
WARNING:
When the CNS O
2
reaches 100% there is
danger of oxygen toxicity. Start procedure to
terminate the dive.
Square tracks your oxygen uptake via the CNS
O
2
clock. If the calculated value of CNS O
2
reaches 100%, 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 100%.
