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).”

(3) O2 OLI bar graph: This indicates CNS toxicity level at the

end of the dive. This drops as your surface interval time

increases.

(4) 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.

(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.

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).
