SHORTCUT TO SET TIME
FUNCTIONS
To speed up the operations for setting
the time, date, second time, alarm and
temperature, Nemo Excel includes shortcuts
to the “Watchset” menu.
To use these shortcuts, simply press the <+> or
<-> buttons to access the desired item. Before
the 10 seconds of display elapse, press the
<enter> button for 2 seconds. This will directly
access the chosen setting.

SET DIVE  DATA FIG 21
Fig. 21
Set Dive - Data mode is used for selecting the
type of water (salt or fresh), which determines
the accuracy of the computer’s depth reading,
as well as the units of measurement (metric
or imperial), and for clearing of the residual
nitrogen memory.
To ensure maximum accuracy, you need to set
Nemo Excel for either fresh water (“Fresh”)
or seawater (“Salt”) as appropriate. Check
this setting often, especially if you use the
instrument in a variety of environments (lake,
sea, swimming pool).
Press the <enter> button after the last item to
return to the SET DIVE menu.
NOTE
Pressing <esc> during the settings cancels
any changes made and reverts to the
preceding value;
pressing <enter> during the settings
accepts the changes made and advances
to the next item or returns to the higher
menu level.

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.
SET DIVE  DATA  DEL TISSUE
This item is used for clearing the residual
nitrogen memory of the tissue compartments
(fig. 22).
Fig. 22
In Set Dive - Data mode, scroll until the
blinking “DELETE” message appears. Press
<enter> to invoke the confirmation options,
which will show a blinking “NO” message. Use
the <+> or <-> buttons to change this message
to “OK”.
Then, once the “OK” message has appeared,
press <enter> to clear the residual nitrogen in
the tissue compartments.
If you do not wish to clear the residual nitrogen
memory in the tissue compartments press the
<esc> button or the <enter> button when the
“NO” message 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 Excel if
you have already dived within the previous
24 hours.
SET DIVE  MODE
Set Dive - Mode is used for setting the general
parameters for the planned type of dive.
This section covers dives using compressed air
as the breathing mix.

NOTE
If you have completed a Nitrox dive and
wish to do a repetitive dive with air, set the
computer for “Nitrox” with O
2
at 21%. By
so doing, the calculation of the %CNS will
remain active.
