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 during the scrolling of no
decompression limits take into account all
the Set Dive parameters, such as the Mode,
Altitude, Personal Correction Factor and, in
the case of EAN dives, the values for oxygen
percentage and its maximum permitted partial
pressure.
To enter Plan mode, scroll through the
Main Menu until the “PLANNING” message
appears on the display bar, and then press the
<ENTER> button.
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
0 m (0 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 (Fig. 28).
FIG. 28
The maximum depth allowed in this case
varies as a function of the % O
2
and maximum
PPO
2
that have been entered.
The <ESC> button returns you to the main
menu.
NOTE
The Plan function will only be active after
having selected AIR or EAN mode in Set
Dive.
LOG BOOK
Log Book 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
the most recent dive, “2” to the preceding dive
and so forth, until the memory is full.
If the memory is full, when the user dives
again the oldest record is deleted to free up
memory for the new dive.
Maximum capacity is approximately 40 hours
of diving with profile points at twenty second
intervals.
To enter Log Book mode, scroll through the
Main Menu until the “LOGBOOK” message
appears on the display bar, and then press the
<ENTER> button.
Log Book
The first page of the log book contains a
summary history of dives with the following
information (Fig. 29):
• maximum depth reached;
• total diving time (hours and minutes);
• total number of dives done;
• coldest logged temperature.
Pressing the <ENTER> button will display the
individual dives.

NOTE
For more extensive data storage,
management and viewing functionality,

LOG BOOK  DIVE #
When viewing the details of the individual
dives, these are numbered sequentially in
reverse chronological order.
The following data are displayed (Fig. 30):
• type of dive (AIR, EAN, BOTTOM TIME).
• sequential dive number;
• alternating dive start date and time.
FIG. 30
Press the <+> or <-> buttons to advance from one
dive to the next.
Press the <ESC> button to return to the
preceding menu.
Press the <ENTER> button to view the details of
the selected dive.
LOG BOOK  TECH DATA
This mode displays the summary details of
each individual dive (Fig. 31):
• Type of dive: AIR, EAN, BOTTOM TIME.
• Maximum depth reached.
• Maximum ascent rate reached.
• “Uncontrolled ascent” icon.
• Omitted deco stop (AIR, EAN only).
• “Deco” icon for decompression-stop dives
(AIR, EAN only).
• Deco stop violation (AIR, EAN only).
• Selected personal correction factor
(AIR, EAN only).
• “No deco” icon for no-decompression dives
(AIR, EAN only).
• Selected altitude program (AIR, EAN only).
FIG. 31
Press the <-> button to choose to view one of
the following on the display bar:
• % O
2
in the breathing mix (EAN only);
• % CNS maximum (EAN only).
Or
• lowest logged temperature,
• duration of the dive.
Or
• type of water (Salt, Fresh);
Press the <ENTER> button to review the profile
of the dive.
NOTE
For dives in BOTTOM TIME mode, the
uncontrolled ascent and omitted deco stop
icons refer to errors committed during the
preceding dive.
LOG BOOK  PROFILE
In Profile mode you can review the profile
points of a dive, spaced at 20 second intervals.
Press the <+> button once to advance to the
next profile point, or hold it down to scroll
automatically.
The details displayed in Profile mode are the
following (recorded at the end of the time
interval) (Fig. 32):
• current depth;
• fastest ascent rate;
• duration of the dive.
As well as any icons such as:
• “deco” icon for decompression-stop dives
(AIR, EAN only);
• omitted deco stop icon (AIR, EAN only);
• personal correction factor (AIR, EAN only);
• “no deco” icon for no-decompression dives
(AIR, EAN only);
• selected altitude program (AIR, EAN only).

PC MODE
Using a special interface unit and a dedicated
Windows software application, you can transfer
all the data from the Nemo Wide log book to
a personal computer. Nemo Wide and the PC
communicate through a special USB interface
module (optional).
To transfer data to the computer, set Nemo
Wide to PC mode:
• Use the <+> or <-> buttons to select “PC” in
the display bar.
• press the <ENTER> button.
Position Nemo Wide with the display facing
upward and plug the interface into the special
port.
More detailed information is available in the
special software required to communicate with
Nemo Wide.
