FIG. 41
Use the <+> and <-> buttons to change your
selection. To clear the residual nitrogen
memory in the tissue compartments press
the <CENTRAL> button when the word “yes”
appears. In order to really clear the residual
nitrogen memory in the tissue compartments
you have to confirm your choice (figure 41-1)
FIG. 41-1
If you do NOT wish to clear the residual
nitrogen memory in the tissue compartments,
press the <CENTRAL> button when the word
“no” appears.
 WARNING
This option is intended only for highly
experienced divers. Users who clear the
residual nitrogen memory cannot use the
instrument for repetitive dives. After this
operation, do not dive with Nemo Air if
you have already dived within the previous
24 hours.
°C METERS / °F FEET
You can select which units of measure you
want to use: metric (°C and m) or Imperial
(°F and ft). The unit of measure flashing is the
current selection (figure 42).
FIG. 42
Use the <+> and <-> buttons to adjust the values.
 WARNING
Before diving, make sure you have
correctly set the units of measurement. An
incorrect setting may give rise to confusion
during the dive, and hence to underwater
behavior errors.
INTRO
You can enable or disable the introduction
displayed each time Nemo Air is switched
on. The default option will enable the initial
display. (figure 43).
FIG. 43
Use the <+> or <-> buttons to adjust the values.
Press the <CENTRAL> button to record
the new setting and move on to display the
following information (figure 44):
FIG. 44
• the serial number;
• the software version;
• the hardware version;
• the number of times the battery has been
replaced;
• the charge level of the battery. When you
enter this section, an automatic battery
check is performed, and while the computer
is measuring power, the string “battery:
check” will display for a few seconds.
There are three possible values for this
measurement:
• battery: OK;
• battery: LO1;
• battery: LO2.
For more information about the level of battery
charge, see the section entitled “Check the
battery power level”.
Press the <CENTRAL> button to move from
one screen to the next, and eventually return
to the SYSTEM menu.
PLANNING: SCROLLING OF
NO DECOMPRESSION LIMITS
This function allows the user to scroll through
the no-decompression limits, automatically
taking into account the current residual
saturation of the tissue compartments from a
preceding dive.
The times shown when scrolling through the
no-decompression limits take into account the
settings under SETDIVE, such as MODE (AIR
or EAN), ALT (altitude), PFACTOR (personal
factor), and, for EAN dives, the %O
2
(oxygen
percentage) and the PPO
2
(maximum partial
oxygen pressure).
From the Main Menu, use the <+> or <->
buttons to select PLANNING, and press the
<CENTRAL> button to enter this mode.
Repeatedly press the <+> button to increase
the depth by three meters each time, up to a
maximum of 48 m (157 ft).
Press the <-> button to decrease the depth
indicated in three-meter increments, down to
12 m (39 ft).
For each depth, the display shows the
corresponding no-decompression time
expressed in minutes.
If EAN mode is enabled, the oxygen percentage
set is also shown (figure 45).
FIG. 45
In this case, the maximum depth allowed in
Plan mode will depend on the values entered
for % O
2
and maximum PPO
2
.
Press the <CENTRAL> button to return to the
PLANNING menu.
NOTE
The Plan function will only be active after
having selected AIR or EAN mode in SET
DIVE.
LOG BOOK
LOGBOOK mode is used for viewing the details
of past dives on the display.
The dives are organized as in the pages of a
“log book”, with the number “1” assigned to
