Additional important information may be ob-
tained by pressing the button during the dive:
1) Maximum PO2 set.
2) Oxygen percentage of the selected mixture
(Air if FO2=21%);
3) Maximum depth which can be reached de-
pending on the maximum PO2 set.
4) Safety Factor SF.
DIVE NITROX FUNCTION: Dive with
Nitrox
(im. 15)
The Leonardo computer keeps the setting of
the percentage of Oxygen Fo2, until the diver
manually resets it to different values. It is im-
portant to understand that:
Artificial respiratory mixtures may ex-
pose the diver to significant risks, unless
they are perfectly known, analysed and
studied. It is mandatory to understand
All manuals and user guides at all-guides.com
that THE MIXTURE BEING BREATHED
MUST BE EXACTLY EQUAL TO THE
ONE SET ON THE COMPUTER. OT-
HERWISE, DECOMPRESSION AND TO-
XICITY INFORMATION provided by the
computer WILL BE DANGEROUS FOR
THE LIFE OF THE DIVER. Before, after,
and during a Nitrox dive, it is mandatory
to verify the percentage of the Oxygen so
that it exactly corresponds to the one in
the cylinder.
BEFORE A NITROX DIVE.
The Leonardo computer always keeps the DIVE
AIR program switched on, until the diver sets it

SET MODE: Dive parameters setting). In this
case the display will show the Nitrox icon (pic-
