3.2.2.  DIVING WITH EAN (NITROX)
3.2.2.1.  BEFORE DIVING 
This dive computer can be set for diving with standard air only (Air mode) or it 
can be set for diving with Enriched Air Nitrox (EAN mode).
If set to the EAN mode, the correct oxygen percentage of the gas in your cylinder 
must always be entered into the computer to ensure correct nitrogen and oxygen 
calculations. The dive computer adjusts its mathematical nitrogen and oxygen 
calculation models according to the entered O
2
% value (Fig. 3.21.). Calculations 
based on Nitrox result in longer no-decompression times and shallower maximum 
depths.
The EAN mode is set using the SET DIVE function (See Chapter 4.3 Dive Mode 
Settings)
DEFAULT NITROX SETTINGS
In the EAN mode, the default setting is for standard air (21% O
2
). It remains in this 
setting until the O
2
% is adjusted to any other percentage of oxygen (22% - 50%).
If a dive is started within 2 hours Mosquito retains this value until the dive series 
is fi nished. If unused, the computer will retain the manually entered value for the 
selected oxygen percentage for about two hours, after which it will revert to the 
default setting of 21% O
2
.
The default setting for maximum oxygen partial pressure is 1.4 bar, however you 
are able to set it in the range of 1.2 - 1.6 bar.
