NITROX – PERCENTAGE OF OXYGEN (FO2)
The percentage of oxygen FO2 can be changed only when the computer is set in SET NITROX MODE.
With this setting you can decide the type of dive: with air (Dive Air Program), with fraction of oxygen at
21%, or using one or two Nitrox hyper-oxygenated mixtures (Dive Nitrox Program).
Mix1 percentage of oxygen (FO2) setting.
To set the correct percentage of Oxygen contained in the Nitrox mixture, press the right (>) button to move
up to the DIVE-S mode. Enter in this mode by pressing the central Mode button. The indication of the
partial oxygen pressure (PO2) and the Mix1 indicator will flash. Press the right (>) button. The indicator of
the percentage/fraction of oxygen (FO2) will flash. Press the central Mode button. The display will show
just the highlighted item (FO2), flashing together with the corresponding maximum operating depth that
can vary by pressing the right or left (> or <) button of the device. Once the desired setting is reached
(values between 21% and 50% with variations of 1% of O2), confirm the value set by keeping the Mode
button pressed for a few seconds until hearing an acoustic signal to confirm exit from the menu. Keep
pressing and holding the central button to return to the main menu (after another acoustic signal) and if it is
still on, the computer will shut down. Alternatively, the computer will modify the automatic setting by issuing
an acoustic signal to return then to the main screen, and then it will automatically shut down.
REMARK: The percentage of oxygen FO2 set in the Mix1 is between 21% and 50%.
Mix2 Percentage of Oxygen (FO2) setting.
To set the correct percentage of Oxygen contained in the Nitrox mixture, press the right (>) button to move
up to the DIVE-S mode. Enter in this mode by pressing the central button (Mode). The indication of the
partial oxygen pressure (PO2) and the Mix1 indication will flash. Press the right (>) button three times until
you see the word Mix2 flashing and the indicator of the Mix2 percentage/fraction of oxygen. Press the
central Mode button. The display will show just the highlighted item (FO2), flashing together with the
corresponding maximum operating depth that can vary by pressing the left or right button of the device.
Once the desired setting is reached (values between 21% and 99% with variations of 1% of O2), confirm
the value set by keeping the Mode button pressed for a few seconds until hearing an acoustic signal to
confirm exit from the menu. Keep pressing and holding the central button to return to the main menu (after
another acoustic signal) and if it is still on, the computer will shut down. Alternatively, the computer will
modify the automatic setting by issuing an acoustic signal to return then to the main screen, and then it will
automatically shut down.
REMARK: The percentage of oxygen FO2 set in the Mix2 is between 21% and 99%.
REMARK: The Giotto computer is factory set on the MODE-S AIR dive program (air with PO2 1, 4). To be
able to access the Nitrox parameters you need to set the MODE-S menu in position NITROX. Mix1 and
Mix2 contain FO2 at 21% and the PO2 at 1.4 factory set by default.
REMARK: If the computer is set in NITROX MODE-S and the default values of MIX1 and MIX2 are
modified, such values remain set and active until it is changed to MODE-S AIR. In this case these values
will restart from the default values.
REMARK: By varying the FO2 the computer indicates the maximum depth which may be reached with that
mixture, depending on the PO2 value set.
It is possible to change the setting of the Nitrox mixture also during the surface interval (with desaturation
in progress), but only after 2 minutes from the start of the interval.
This is a very important feature, especially for divers who perform a series of subsequent dives, which
allows them to change the mixture after having dived without having to wait for complete desaturation.
IMPORTANT: Once the percentage of oxygen FO2 is set, it remains active and memorised in the computer
until it is modified again or until the MODE-S menu is set in AIR.
DANGER: With the NITROX MODE-S Giotto always keep the last percentage of oxygen set. It is very
important for the diver's safety to always check this parameter before each dive.
DANGER: If you perform a repetitive dive after a Nitrox dive, it is fundamental for one's safety to check the
