The maximum permitted depth will vary depending
on the values entered for % O
2
and maximum
PPO

.
In "Bottom Time" mode, scrolling of the no
decompression limits is inhibited (fig. 35).
FIG. 35
In "Air" or "Nitrox" mode, scrolling of the no
decompression limits is inhibited if the Stop
condition is active (fig. 36).

DIVE SIMULATOR
Fig. A shows the different ways for accessing SURF
mode, i.e by pressing the <Mode> button from
PLAN mode or by pressing the <-> button from
LOG mode.
The DARWIN can simulate dives taking into
account the current residual saturation of the
diver's tissues. In the case of "Nitrox" dives, the
simulation also takes into account the settings for
% O
2
in the breathing mix and for maximum PPO
2
.
If the DARWIN is in "Bottom Time" mode, the dive
simulator function is inhibited. In "Air" or
"Nitrox" mode, the dive simulator function is
inhibited if the Stop condition is active.
To enter SIMUL mode, press the <Mode> button for
2 seconds (fig. E). This simulation mode phases are:

Press the <-> button to start simulating the dive.

The simulation time runs 5 times faster than real
time. In other words, after 12 seconds of real time,
one minute will have passed in the simulated dive.
The DARWIN displays the data in the same way as
for a real dive, again dividing it into two display
layouts. At approximately 20 seconds intervals, the
WIN1 display layout is replaced by the WIN2 which
shows the maximum depth and the ascent time;
after approximately 4 seconds the display reverts
to showing the WIN1 layout.
Button functions:
Press and release the <-> button to increase the
depth by 1 meter (3.28 feet) each time.
Repeatedly press and release this button to
simulate a descent rate of 12 m/minute (39.3
ft/minute). Keep it pressed to simulate a descent
rate of 24 m/min (78.7 ft/min).
Press and release the <Mode> button to decrease
the depth by 1 meter (3.28 feet) each time.
Repeatedly press and release this button to
simulate an ascent rate of 12 m/min (39.3
ft/min). Keep the <Mode> button pressed to
simulate an ascent rate of 18 m/min (59 ft/min).
Press <Mode> and <-> simultaneously to exit SIMUL
mode.
SIMUL - S
URFACING
When the depth is less than one meter (3.28 feet),
the DARWIN considers the diver to be at the
surface. The display shows the maximum depth
reached and the duration of the simulated dive.
Press the <-> button to resume the dive.
Press <Mode> and <-> simultaneously to exit
SIMUL mode.
SIMUL - P
OST DIVE SURFACE TIME
On surfacing from the simulated dive, the DARWIN
switches to surface mode and displays the surface
time. This value increases quickly because the
simulation time runs even faster than during dive
mode (one real-time second = one minute in the
simulated surface time). Press <Mode> to switch
to a display of the "desat time".
