Ascent time – length of time needed to reach the surface. It includes ascent speed, deep stops (if
selected) and decompression stops. Ascent time is displayed instead of of No deco at the moment
when decompression stops become necessary.
Deep Stop – additional stops in the deeper part of the dive. Deep stops can prevent could the
formation of microbubbles. Deep stop is available in screen 1 only.
Max depth – maximum achieved depth
CNS – proportion of maximum oxygen exposure in relation to oxygen toxicity, expressed as a
percentage
Floor – depth level where the duration of decompression is not increasing
Temperature – current temperature in Celsius or Fahrenheit (depending on the settings)
pO2 – partial pressure of oxygen depending on the oxygen fraction and ambient pressure
Decompression-status graphic symbol – graphically shows different decompression situations. For
an overview of decompression status, see below.
Battery-status graphic symbol – graphic symbol of battery status: green when fully charged, yellow
when at 50%-30% capacity, orange at 30%-10% capacity, red when the battery charge is lower than
10% of capacity.
Open circuit MENU
Throughout an entire dive the Open circuit menu remains available. For Switching to menu, press
BOTH KEYS.
Mix – Select your current mix or switch to another decompression mix
End dive – terminates the dive manually. A condition for use of this function is that the depth must
be less than 0.5 m.
Mixture setup – set or correct proportions and enable or disable used gases.
Games – switch to games during deep or safety stops
Switch off – switch off the whole computer. A condition for use of this function is that the depth
must be less than 0.5 m
Symbols legend
Symbols are displayed during the dive in Open circuit or SCR/CCR mode. These symbols appear in the
right-side column on the display. They represent the current situation and recommend procedures to
divers.
No Deco. Free ascent
