3 minutes, Nemo Wide considers the dive to be
finished and records its data in the log book memory.
If the diver does re-descend within 3 minutes, the
dive continues and the dive timer resumes from
where it left off.
Data displayed in Surface mode (Fig. 20):
• duration of the dive;
• maximum depth;
• icons for any mistakes made during the
dive(omitted stop, uncontrolled ascent).

WARNING
If an AIR or EAN dive ends with an
uncontrolled ascent or an omitted stop,
Nemo Wide will restrict Dive - AIR and Dive
- EAN modes for 24 hours and will only allow
the BOTTOM TIME operation mode.
NOTE
The buttons in surfacing mode are disabled.
!
WARNING
Do not fly or travel to high altitudes while
the no-fly indication remains active.
SURFACE MODE AIR
When the dive is considered finished, Nemo Wide
switches from Dive mode to Time mode, indicating
the desaturation time in the display bar as well as
the NO FLY icon (Fig. 21).
FIG. 21
In addition, Nemo Wide displays the icons for
any errors made during the dive (omitted stop,
uncontrolled ascent).
You can also use the <+> and <-> keys to view the
no-fly time, the time, date, and temperature.
The <ESC> button returns you to the main menu.
DIVE EAN
Due to the lower percentage of nitrogen in the
breathing mix, oxygen-rich mixtures make it
possible to extend the no-decompression limits, as
compared with the same dive with air.
However, the higher oxygen content in the mix
exposes the diver to oxygen toxicity hazards which
are not generally encountered in recreational dives
with compressed air.
In EAN mode, Nemo Wide computes oxygen toxicity
on the basis of the dive time, the depth and the
oxygen percentage setting, providing indications
that enable the diver to remain within the safe limits
for oxygen exposure.
To do a EAN dive, you must select the EAN mode in
the Set Dive - Mode menu.
Nemo Wide handles EAN dives in a similar manner
to compressed air dives. That means that you
will have the same functions and procedures for
selecting the Dive mode.
The only differences in managing the two types of
dives concern the settings for general parameters
for EAN dives and the of display these parameters
in addition to the normal air dive parameters
(discussed in the preceding section).
This section will examine the general parameters
for EAN dives monitored by Nemo Wide and the
differences in how the data are displayed.
