ALADIN SQUARE USER MANUAL
1. INTRODUCTION TO
SQUARE
Your Square User Manual is divided into
fi ve main chapters.
1 Introduction to Square. This chapter
provides an overview of the Square
computer and describes its operating
modes and functions when on the surface.
2 Square as a dive computer. This
chapter describes all settings and functions
of Square as a dive computer and takes
you underwater with Square. It’s about
everything Square can and will do to
enhance your safety and fun underwater.
3 Square accessories. This chapter
describes briefl y the Square extras that you
can purchase to get maximum out of your
dive computer in all conditions.
4 Square PC interface. This chapter is
about personalization and customization.
It describes how to change settings, to
download and manage your logbook.
Square is a technologically-advanced
instrument that can accompany you
during your underwater adventures while
providing you with accurate depth, time
and decompression information.
The buttons allow operating functions,
access menus and changing settings while
on the surface. During the dive they set
bookmarks; show further information on
the computer screen, change the gas and
activate the backlight.
Square has been designed for easy use
from the fi rst day on for the beginner with
standard factory settings but the selections
and features allow the advanced user
to customize according to their specifi c
needs. So, it is recommended to study and
understand this manual before diving with
your Square.
It is time to dive into the details now. We
hope you will enjoy getting to know your
new computer and we wish you many
happy dives with Square.
1.0.1 Buttons
Square has one navigation button. It can be
pressed from left or right side. The shape
has been selected so that even with thick
neoprene gloves you can follow the button
from left to right with your fi nger without
loosing the touch of the button.
Both left and right ends of the navigation
button have different functions when pressed
short or pressed and hold (long press).
Generally the buttons operate as follows:
Left short = scroll left at the menu “left”, “L”
Left long = escape “ESC”
Right short = scroll right at the menu “right”, “R”
Right long = select or confi rm the setting “SEL”

ALADIN SQUARE USER MANUAL
1.0.2 Display
The display information has been divided in
a pattern of a dive profi le.
Various situations like ascent, descent,
stops can be easily located from the profi le.
1.0.3 Heart Rate Option
Square fi rmware may be delivered without
the heart rate option. In this case please
ignore the user manual descriptions
referring to heart rate functions.
1.0.4 Battery
Square uses a battery of the type CR2450
which is available from your SCUBAPRO dealer.
Square will shortly test the battery status
after each activation (switch on) and
indicate only the state if the battery is too
low. In addition, you can verify the status
of the battery by providing the check at the
main menu: Checking the battery status.
NOTE: A battery level indication
LO means that battery has some
reserve left but battery change is
recommended before a dive. Also,
with LO level battery the backlight and
alarm tones are not activated.
WARNING
Starting a dive when the battery LO is indicated can
cause the computer to fail during the dive! Replace
the battery before any diving activity if the battery
LO appears. When the ‘do not dive symbol’ appears
with the text change battery Square can not be
used for diving before a fresh battery is replaced.
Please refer to chapter Checking the
battery status for details how to check
your Square battery status.
WARNING
Replacing the battery requires opening the
electronic compartment of Square. You must take
extreme care when performing the battery change
operation in order to ensure the water tightness of
the dive computer. Failing to do so will cause the
dive computer to  ood during your next dive and
permanently ruin it. Damage to Square due to an
improper battery replacement is not covered by
warranty. We strongly recommend having the
battery change operation be carried out by your
SCUBAPRO appointed dealer.
See chapter Replacing the battery in
Square for information on how to replace
the battery.

ALADIN SQUARE USER MANUAL
1.0.8 Checking the Altitude
At the altitude menu the current altitude is
calculated from the barometric pressure
and shown at the bottom row left. The
current altitude class is shown at middle row
right and this is used as ambient pressure for
diving algorithm calculations. At the bottom
row right the current temperature is shown.
NOTE: barometric pressure is a variable
changing with weather and atmospheric
pressure at that elevation. Dive algorithm
uses Altitude Classes which are directly
derived from the barometric pressure.
Altitude is counted from the current
barometric pressure and it is therefore a
relative value.
The altitude can be adjusted when current
elevation is known by pressing the SEL. The
altitude value will start blinking. By pressing
right or left the value can be adjusted in
10m/50feet steps. By pressing SEL you
can confi rm the altitude value. Adjusting the
altitude elevation has no effect on altitude
class. More about diving in altitudes is
explained in chapter Altitude diving.
NOTE: Different combinations m&˚C,
Ft&˚C, m&˚F or Ft&˚F can be selected
from the dive mode menu: Units.

also using following information:
1. Selected oxygen concentration and
active tanks
2. Selected water type
3. Selected MB level
4. Water temperature of the most recent dive
5. Altitude range
6. Status of tissue saturation at the time the
planner is started
7. A normal workload of the diver and
observance of the prescribed ascent rates.
By pressing SEL at the planner menu you
will get into the planner directly or to the
surface interval setting (repetitive dive).
NOTE: When Square is in Gauge or
Apnea modes the Planner is disabled
and Planner OFF is shown in this menu.

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.
