(2) O2 OLI bar graph: This indicates CNS toxicity level at the end of
the dive. This drops as your surface interval time increases.
(3) Nitrogen (N2) exposure bar graph: This is the amount of residual
nitrogen in your body at the end of the dive. This drops as your surface
interval time increases.
(4) Desaturation time: This is the amount of time, expressed in hours
and minutes, that must pass before the residual nitrogen levels drop to a
point where subsequent dives are treated as a single (non-repetitive)
dives. This is not the same as “time to fly (see no-fly symbol below).”
(5) No-fly symbol: This symbol, when displayed, indicates that you
should not fly or go to any altitude higher than the one you are diving
in until it disappears from the screen.
When the computer finishes calculating your desaturation time and
your surface interval time is over 12 hours, the no-fly symbol turns off.
If the computer finishes calculating your desaturation time and your
surface interval time is not over 12 hours, then the no-fly symbol stays
on until 12 hours of surface time have passed.
Note: If the dive was made in “Gage” mode, the “Gage” icon will be
displayed and the OLI and N2 bar graphs will not be displayed.
Note: After a dive in “Gage” mode, you will be responsible for
calculating your own desaturation and surface-interval times.
WARNING: It is recommended that you wait at least 24-hours
following any dive before flying in an aircraft or driving to altitude.
Failure to allow sufficient surface interval time before doing so may
increase your risk of decompression illness (DCI).
