DIVES OUTSIDE THE SAFETY CURVE (DECOMPRESSION)
DANGER: Do not use this instrument to make dives outside the safety curve!
Cressi advises against using this computer to make decompression dives.
However, if during a dive, due to carelessness or in an emergency, you have to
overstep the limits of the safety curve, GOA/CARTESIO can assist you by providing
all the information necessary for a correct ascent and the relative decompression
steps.
When a dive goes outside the curve, the computer gives out an audible alarm
and at the same time the display screen changes as shown in the figure below, to
display the following information:
• Stop icon with the word DEC ashing in the lower part of the display, telling
you that you have left the safety curve and will have to make decompression
stops. The arrow pointing upwards flashes to encourage you to start your
ascent.
• Depth of the rst decompression stop to be made (the deepest one), expres-
sed in metres (m) or feet (ft.). This may vary from a maximum of 24 m to a
minimum of 3 m, in 3 m decrements.
• Time in minutes of the rst decompression stop to be made (the deepest
one).
• TOTAL icon indicating total ascent time, i.e., the time required to reach the
deepest stop, respecting the proper ascent rate, plus stop time at that depth
DECOMPRESSION PREWARNING ALARM
Whenever the time still available within the curve, as shown on the display by the
NO DECO icon, drops to 3 minutes, GOA/CARTESIO gives out an audible alarm.
In this situation, we are about to overstep the limits of the safety curve and begin
a dive that requires decompression.
DEEP STOP
To avoid the risks arising from the microbubbles that form during the ascent,
GOA/CARTESIO is able to suggest a DEEP STOP lasting one or two minutes (in
a dive with decompression), to be made at a variable depth as a function of dive
prole. During a dive, if its prole requires it, the words DEEP STOP appears on
the display and an audible signal is heard. The STOP icon appears with the values
of stop depth and time in minutes. If the diver does not make the Deep Stop, the
warning is deleted and the computer plans an ascent without deep stop.
NOTE: Make sure that the deep stop function is ON (see DIVE SET).
NOTE: In this situation, the maximum depth may be seen by pressing the
scroll UP /DOWN button.
