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”

English

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

By simply pressing buttons right or left from the time of day display you can scroll through the various menus in SQUARE. The chart above shows the sequence of the menus. Note that when you ﬁ rst reach a menu, you are “outside” of it. You must press SEL to enter the actual menu.



NOTE: When Square has wet contacts

activated and they detect moisture in between, the Square goes automatic to Surface display.

1.0.6 Surface display

When you have not been diving with your Square for a while (no desaturation left) the surface mode may appear as shown below, indicating settings like the operation mode (scuba, gauge, apnea), water type, heart rate, MB level and gas mix:

After a dive the display may appear as shown below, indicating maximum allowed elevation where diver may ascent, desaturation time and no repetitive dive symbol (too short interval):

1.0.7 Surface interval counter

After a dive you can check your surface interval by pressing SEL at the surface display. The text Int and a time appears to the display. The surface interval counter counts until desaturation is complete, after that this display cannot be selected.

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.

1.0.9 Planning a dive

Planner

SEL

You can plan your next dive based on your body’s nitrogen saturation. The planner is 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

given to the GAS1. If GAS1 MOD is shallower than 9m/30feet, planning is not allowed and information LO ppO2 is shown.

The gas oxygen content and maximum ppO

settings are given at the dive mode

menu: SET GAS.

WARNING

If you have set ppO2max to OFF, the planner will allow depths up to maximum of 120m/394ft. Air/nitrox dives with high ppO2 are extremely dangerous and can lead to death. Be aware that exposures to high ppO

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 nostop 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 O2% 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.
