1.2. OPERATING MODES
The functions of the Genius computer can be grouped into three categories, each corresponding to a specific mode of operation:
• surface mode: the computer is dry on the surface. In this mode you can change settings, review your logbook, use the dive planner, see remaining desaturation after a dive, download to PC and much more;
• dive mode: the computer is at a depth of
1.2m/4ft or more. In this mode, Genius monitors depth, time, temperature and performs all decompression calculations; dive mode itself can be broken down into 4 sub categories:
- pre-dive (Genius is on the surface but
actively monitoring ambient pressure, so that it can begin to calculate a dive the instant it is submerged below 1.2m/4ft);
- dive
- surfacing (Genius is on the surface at
the end of a dive; dive time calculation is halted but if the diver submerges within threeminutes the dive is resumed including the time spent on the surface; this for instance would allow a diver to surface momentarily to set a bearing towards the boat, then submerge again and swim towards the boat);
- post-dive (after the threeminutes of
surfacing mode, Genius closes the logbook and reverts to a display showing desaturation time, no-fly time and surface interval; this lasts until the desaturation and the no-fly time both have been reduced to zero);
• sleep mode: the computer is on the surface after 3 minutes without operation (10minutes from pre-dive mode). Though the computer appears to be turned off completely, it is still active. Genius computes tissue desaturation and checks the ambient pressure once every 20 seconds for uninterrupted monitoring of the environment.
1.3. TURNING ON GENIUS AND
MAIN MENU
To start the computer, press the left button. This brings up the home display, shown in Figure 1. The home display provides at-a­glance information about time, temperature, battery status, settings of the algorithm and, when paired to an active transmitter, tank pressure. From the home display you can call up the main menu with all available settings and functions, but you can also directly reach certain useful functions such as logbook, dive planner, gas and algorithm settings, bluetooth connection.
Once in the main menu, you will see the familiar look of an icon-based user interface. From the top left, in sequence, there are:
SET DIVE: here you can review and set all parameters relating to a dive;
SET COMPUTER: set the language, the clock, display brightness and more;
COMPASS: from within this menu you can use the compass while on the surface, for instance to set a bearing which you will call up later on in the dive to navigate towards a wreck;
INFO: find information about the hardware and firmware of your Genius;
MAPS: view all maps uploaded to your Genius;
PHOTOS: view all images uploaded to your Genius;
BLUETOOTH: establish a bluetooth connection to a device such as a smartphone;
BUTTON LOCK: lock the buttons so that the battery is not accidentally drained during travel.
1.4. RECHARGEABLE BATTERY
Genius uses a lithium-ion rechargeable battery. A full charge allows you up to 40 hours of diving, depending on the usage of the high intensity on the backlight and the temperature of the water. The display alerts you of the status of the battery. The four possible situations are described as follows:
- A solid green battery symbol means Genius has between 70 and 100% charge;
- A partially filled green battery symbol means Genius has between 40 and 70% charge, still enough for safe diving;
- A partially filled yellow battery symbol means Genius has between 20 and 40% charge.
- A partially filled red battery symbol means Genius has between 0 and 20% charge. This is not sufficient to ensure a safe dive hence the computer is disabled from functioning.
In the event that the charge drops below 20% during a dive, the message LOW BATTERY appears on the display. When you see this message, you should consider starting a safe ascent as there may not be enough charge to continue diving.
WARNING
- Starting a dive with less than 20% charge can cause the computer to fail during the dive. Recharge the battery as soon as you notice this message.
- In sleep mode Genius uses up the battery at a a very slow rate. If you haven’t used Genius in several weeks there may be a noticeable drop in battery level, so you may have to recharge it before diving.
- Leaving Genius unattended for long periods of time such that the battery will be completely discharged does not harm neither the battery nor Genius. Logbook data and all settings will be saved. After charging you must however set the time and date again.
- When the battery in Genius is completely discharged, it may take up to 20 minutes from the moment it is connected to a power source before Genius reacts.
- Temperature can noticeably affect battery performance. A low battery warning may appear when diving in cold waters even if you think that the battery should have sufficient charge.
- It is advised that you charge the battery if you intend to dive in cold water.
The rechargeable battery has a life time of approximately 500 charging cycles. Please contact your authorized Mares dealer if you need to replace it.
1.4.1. CHARGING THE BATTERY
The battery takes about 4 hours to charge from completely empty to completely full when using the adapter that came with the computer. It can take up to 8 hours when using a standard adapter as not all adapters feed the same current to the USB port. To charge the battery, use the special clip and the USB cable, connecting it either directly to a power supply or to the USB port of a PC.
1.5. COMMUNICATING VIA USB CABLE OR BLUETOOTH
Genius can communicate via low power bluetooth directly to a smartphone, a PC or a Mac. The data transfer is such that only logbook information can be transferred via bluetooth while firmware upgrades and image or map uploads have to be carried out via PC or Mac.
To connect Genius to a PC or Macintosh computer, use the dedicated clip and the USB cable. Once connected, Genius will show the USB symbol on the display.
To initiate a bluetooth connection, press and hold the BT button from the home display or select the start the MySSI app on your smartphone and follow the instructions.

1.6. BUTTON OPERATION
Genius has four buttons. These buttons allow you to access menus and change settings while in surface mode. During the dive they switch displays, call up the compass or the map function, and allow to display further information on the computer screen. The function of each button is identified by a set of letters or an icon placed just above the button itself. In certain circumstances, for instance when erasing a set bearing in the digital compass or when calling up the gas switch function during a multigas dive, a button can perform two tasks, depending on whether it is pressed and released or pressed and held for one second.
In such case, there will be two groups of letters or icons above a button: the left one corresponds to the press-and-release action, the right one to the press-and-hold action.
From the home display you have the following possible operations (press/press and hold) for the buttons from left to right (Fig. 1):
- PRE/POST: enters PRE dive mode/enters POST DIVE mode (only if there is remaining desaturation in the computed tissues);
- LOG/PLAN: enters the logbook/enters dive planner mode;
- GAS/GF: enters oxygen and helium setting menu/displays gradient factor settings table;
- MENU/BT: goes to main menu/starts bluetooth connection.
During a dive, icons are used to define the button function. From left to right you will see (Fig. 2):

1.7. IN CASE OF EMERGENCY ICE
Genius allows you to enter information about yourself, such as name, contact information, emergency number, insurance policies and allergies. This information is entered via the PC software Dive Organizer. Alternatively, it can also be entered via the Divers’ Diary Mac software. The first two lines of the ICE are displayed in the home display.
1.8. MOUNTING AND PAIRING OF THE TANK MODULE OPTIONAL
Genius features an exclusive two-way communication technology through which it can communicate with up to 5 tank modules regarding tank pressure and gas consumption information via patented interference-free communication. Each tank module needs to be mounted on a high pressure port of a first stage regulator.
In order for Genius to display tank pressure and gas consumption information, you must first establish a channel of communication between the tank module and Genius. This is called pairing. This operation needs to be performed only once and ensures a permanent and interference-free link between the two devices.
NOTE
To perform the pairing operation, the tank module must be pressurized to at least 15bar/220psi. Hence it must be mounted on a first stage regulator, which is itself mounted on a full scuba tank and the valve opened.
To mount the tank module on the first stage regulator, first remove the high pressure port plug, then screw in the tank module gently by hand until you feel a minimum of resistance, then use a 19mm wrench to tighten it (Fig. 3).
NOTE
- Do not force the tank module while holding it by the plastic cap.
- Do not overtorque while using the wrench: the o-ring seal is assured as soon as you feel the first resistance. The only reason for using a wrench to tighten a bit more is to prevent the tank module from unscrewing itself over time.
The Mares tank module communicates via radio frequency with Genius. For best transmission, we recommend positioning the tank module as described in Figure 4.
To pair the tank module with the Genius, proceed as follows:
- Open the tank valve to pressurize the tank module. You now have two minutes to
perform all steps listed below;
- Go into SET DIVE/GAS INTEGRATION/PAIR DEVICES
- Choose the channel that you wish to assign to the device (if this is your only tank module for single gas diving, choose G1. G2 through G5 are used for multigas dives. More information on this in section 11);
- Place Genius at about 15 cm / 6 inches from the tank module as shown in Figure 5.
- Push SELECT and wait until the progress bar advances to the end. You will either see the message PAIRING SUCCESSFUL or PAIRING NOT SUCCESSFUL. In the first case you have successfully established a connection, in the second you need to repeat the operation, but you must turn off
the valve and depressurize the first stage completely, then wait 1 minute before attempting again.
NOTE
- When diving with more than one gas mixture, tanks G1 through G5 must be set to increasing oxygen levels. Refer to section 11 for more information on multigas diving.
- A tank module can only be paired to one channel on one Genius. If you pair the same tank module to a second channel on the same Genius or to a second Genius, the first one will be erased.
After a successful pairing of G1 to Genius, the home and the pre-dive display will show the tank pressure in either bar or psi. If tank G1 has not been paired, Genius will show an empty field instead of a pressure value. If G1 has been paired but Genius is not receiving any signal, it will show - - - instead of a pressure value.
NOTE
- The Mares tank module has a range of approximately 1.5m/5ft.
- If a tank module battery is weak, Genius alerts you with a screen message referencing the channel designation assigned to the tank module in question.
- During a dive, you can ask Genius to display the battery status of the tank module. More information about this in section 8.5.6 and 9.
Refer to the dedicated tank module manual for information on how to replace the battery in the tank module.
NOTE
- You do NOT need to repeat the pairing procedure after a battery replacement in the tank module.
- You do NOT need to repeat the pairing procedure if the battery in Genius is completely empty.
- You do NOT need to repeat the pairing procedure after upgrading the firmware in your Genius.
1.9. TURNING OFF GENIUS
Genius turns off automatically after 3 minutes without operation when in surface mode and after 10minutes without operation when in pre-dive mode. From the main menu, you can also turn it off manually by selecting the BUTTON LOCK icon.

WARNING
- Diving with Nitrox may only be attempted by experienced divers after proper training from an internationally recognized agency.
- Before every dive and after changing the tank, you must make sure that the set oxygen concentration in Genius corresponds to the oxygen concentration in the tank. Setting the wrong oxygen concentration can lead to serious injury or death.

2.2. ALGORITHM
Genius employs the unmodified Bühlmann ZH-L16C algorithm with gradient factors. Gradient factors are used to lower the maximum tolerated supersaturation in the tissues with respect to Bühlmann’s original values. This results in less nitrogen in the body at the end of the dive, which under normal circumstances makes the dive safer. Gradient factors are expressed in pairs: the first value, also called GF low, represents the percentage of the original Bühlmann value that defines the beginning of the final ascent (relevant only in decompression dives); the second value, also called GF high, represents the percentage of the original Bühlmann value that defines the residual nitrogen at the surface at the end of a dive. As an example GF 50/85 will get you to the surface with a 15% additional margin with respect to Bühlmann’s original maximum tolerated supersaturation and, if this was a decompression dive, your first decompression stop would have been at a depth such that you would not have exceeded 50% of Bühlmann’s original value at that depth.
For more information about gradient factors, please refer to
www.mares.com/sports/diving/gradientfactor
From the home display, press and hold the third button from the left (GF) to display a table listing all settings (Fig. 6).
2.2.1. MAIN GF
This is where you set the conservatism level of the ZH-L16C algorithm via gradient factors. We use Bühlmann’s original values reduced by 15% as a starting point, and you can make the algorithm more conservative from there. There are four predefined sets of gradient factors with increasing conservatism from R0 (85/85) to R3 (50/60) for recreational dives and from T0 (30/85) to T3 (25/40) for tech dives. You can also enter the GF low and GF high values directly via the CUSTOM setting. The default value is R0 (85/85).
2.2.2. ALTERNATE GF TO BE INTRODUCED VIA FREE FIRMWARE UPGRADE SOON
Genius allows you to define an alternate set of gradient factors, to use when you need to cut your decompression short in case of an emergency. The set of alternate gradient factors cannot be more conservative (i.e. lower) than the main set of GF values. The default value is R0 (85/85).
ALL SILENT MODE
ASCENT VIOLATION
Allows you to silence the dive computer.
Allows you to turn off the dive violation due to uncontrolled ascent. This is for dive instructors only, who may find themselves in such a situation because of their teaching requirements.
