The percentage of oxygen (FO2) in the nitrox mix being used must be 'set be-
fore each nitrox dive', unless the FO2 50% Default feature is set OFF (a user set-
ting).
The Dive Planner provides predicted times for subsequent dives. Depending on
cylinder size, breathing gas consumption, and oxygen accumulation, you may
have less time available than indicated because of breathing gas quantity or
other limitations.
Until it has shut itself off, you must not use the ATMOS ai at a different Altitude
than the Altitude at which it was activated. Doing so will result in an error equal
to the difference in barometric pressure, and possibly a false dive mode with er-
roneous data.
The ATMOS ai cannot sense changes in ambient pressure while it is wet.
Use the Yellow Caution Zone of the Nitrogen Bar Graph as a visual reference to
provide a greater margin of protection between you and the No Decompression
Limits.
Every effort should be made to keep each of the Bar Graphs in the green
throughout your dives to reduce your risk of exposure to decompression sick-
ness, oxygen toxicity, and the effects of excessive ascent rates.
