Delayed Violation Mode #1 (Fig. 97)

If you remain above the Required Ceiling Stop Depth for more

than 5 minutes, the full Tissue Loading Bar Graph and Total

Ascent Time will flash until you descend below the Required Stop

Depth.  Also, the graphic message DOWN > TO > xxFT (M) will

continue to scroll. This is a continuation of a Conditional Viola-

tion

Delayed Violation Mode #2 (Fig. 98)

The ATOM cannot calculate decompression times for Stop Depths

much greater than 60 feet (18 meters) and offers no indication of

how much time spent underwater would result in the need for a

greater Stop Depth.

If the Decompression obligation requires a Ceiling Stop Depth

between 60 feet (18 meters) and 70 feet (21 meters), the Tissue

Loading Bar Graph will flash.  Total Ascent Time will still be

displayed.  The graphic message DECO > STOP > 60FT (20M)

will scroll at the top of the display.

When this occurs, you must make a controlled Ascent to just

deeper than, and stay as close as possible to 60 feet (18 meters)

without causing the Total Ascent Time digits to flash.  When the

Required Stop Depth indicates 50 FT/ 15 M, etc., you can

ascend to those depths and continue decompressing.
