A:
No, provided you do NOT replace the batteries
within the 10 minutes after the end of your
dive.
Q:
What happens if I replace the batteries after a
dive, before the desaturation time has gone to
zero?
A:
The tissue desaturation calculation will be
aborted, and when you put in the new
batteries the tissues will be completely
desaturated. Do not use the computer for at
least 24 hours.
Q:
How do I use the backlight when I am on the
surface?
A:
From DIVE mode, press the <-> button for
approximately 2 seconds. The backlight will
illuminate in timer-controlled mode.
Q:
What happens if I start a dive with the
DARWIN switched off or in some mode other
than DIVE mode?
A:
The DARWIN will switch to DIVE mode and
indicate the correct depth, automatically
within 30 seconds, or immediately on pressing
the buttons.
Q:
If I select "Air" or "Nitrox" mode after
completing a dive in "Bottom Time" mode, how
will the dive be managed?
A:
DARWIN does not allow you to do an "Air" or
"Nitrox" dive within the 24 hours immediately
following a "Bottom Time" dive. In this case,
the DARWIN will switch to "stop mode".
Q:
After replacing the batteries, the display
illuminates and some numbers appear: what do
they mean?
A:
They are the serial number.
MAINTENANCE
REPLACING THE BATTERIES
Replacing the batteries is a very simple operation
which can be performed directly by the user.
Unscrew the water-tight cover by rotating it
through a ¼ turn in the anticlockwise direction and
replace the batteries, being careful to insert them
with the correct polarity.
The correct polarity is indicated on the back of the
instrument.
The battery compartment is watertight and non-
communicating with the core of the instrument.
If water leaks inside the battery compartment, just
dry it carefully to remove all moisture before re-
installing the batteries.
Do not throw the old batteries away at sea!
!
CAUTION
Do not replace the battery within the 10
minutes immediately following a dive.
Replacing the battery too soon after the
dive will result in loss of the data for that
dive. In any case, remember that replacing
the battery causes the residual nitrogen,
desaturation time and no-fly time data to
be lost. It is therefore advisable to make
a note of this information before
replacing the battery. Do not replace the
battery between repetitive dives.

WARNING
TO CLOSE THE COVER AGAIN, FIRST PUSH
IT ALL THE WAY IN, THEN ROTATE THE
COVER BY A ¼ TURN IN THE CLOCKWISE
DIRECTION. WARNING: BEFORE ROTATING
THE COVER TO LOCK IT IN THE CLOSED
POSITION, MAKE SURE IT HAS BEEN
PUSHED ALL THE WAY IN, COMPLETELY
UP AGAINST THE COMPUTER BODY. AFTER
CLOSING THE BATTERY COMPARTMENT,
DOUBLE-CHECK THAT THE COVER HAS
BEEN CLOSED CORRECTLY, AND IS
PERFECTLY INSERTED IN ITS SEAT.
!
WARNING
BEFORE CLOSING THE BATTERY COVER,
CHECK THE CONDITION OF THE O-RING,
MAKE SURE IT IS PERFECTLY CLEAN AND
CORRECTLY POSITIONED WITHIN ITS SEAT
IN THE COVER, AND LUBRICATE LIGHTLY
WITH SILICONE GREASE.
