DIVE COMPUTER NEMO WIDE
NOTE
The alarm for any deep stops always
remains active.
!
WARNING
The audible alarms should only be disabled
by experienced divers, who take full
responsibility for this operation.
EAN
This section addresses dives using EAN as the
breathing mix.
When you see the word EAN in Set dive - Mode,
press the <ENTER> button.
The general parameters for EAN dives are the same
as those for compressed air dives (AIR), with the
addition of settings for the percentage of oxygen
and its maximum partial pressure.
We recommend that you carefully read the “Set
dive - Mode - AIR” section before proceeding
further.
• oxygen percentage (%O
2
) in the mix;
• maximum O

partial pressure (PPO
2
);
• altitude;
• personal correction factor;
• uncontrolled ascent;
• audible alarms.
!
WARNING
The use of oxygen rich mixes exposes
the diver to different hazards from those
associated with compressed air. The
diver should be aware of these risks and
understand how to avoid them.
!
WARNING
Do not use breathing mixes with an oxygen
percentage greater than 50%.
!
WARNING
It is essential to correctly set the oxygen
percentage in the mix to ensure correct
readouts of:
• no decompression time remaining;
• decompression stop times;
• alarm on exceeding the maximum
permitted PPO
2
.

The percentage of oxygen in the mix can be
adjusted within the interval 21% - 50%, in increments
of 1%, (Fig. 8).
FIG. 8
Use the <+> or <-> buttons to enter the desired
value.
Press <ENTER> to save the oxygen percentage and
advance to the next setting.

Nemo Wide sounds an alarm when the partial
pressure of oxygen reaches a pre-established limit.
This limit can be varied from a minimum 1.2 bar to a
maximum of 1.6 bar, in increments of 0.1 bar.
Use the <+> or <-> buttons to enter the desired
value.
As this value changes, Nemo Wide will show the
maximum dive depth compatible with the oxygen
percentage and maximum partial pressure that
have been programmed (Fig. 9).
FIG. 9
Press <ENTER> to save the value and move on to
the following settings, which are altitude, personal
correction factor, uncontrolled ascent, and audible
alarms covered in the previous AIR section.
BOTTOM TIME
This section addresses dives using BOTTOM TIME.
You can set the audible alarms here.
When you see the word BOTTOM TIME in Set dive -
Mode, press the <ENTER> button.
