As previously described, you would then need to follow the ceiling stop depths
and times toward the surface as the Nitrogen Bar Graph recedes into the yel-
low Caution zone. Upon reaching 'zero' Total Ascent Time Remaining, you
should continue decompressing until the bar graph segments are well inside of
the green No Decompression zone.
The Aeris 300G will emit one long beep then continue to beep once per second
until you descend below the required ceiling stop depth.
2. Your necessary decompression requires a ceiling stop depth be-
tween 60 feet (18 meters) and 70 feet (21 meters).
In this situation the Nitrogen Bar Graph will flash (Fig. 58). The Aeris 300G
will emit One Long Beep. Total Ascent Time needed to get back to the surface
will still be displayed numerically in the Main Time display.
To get back to the surface, you must safely ascend to just deeper than 60 feet
(18 meters) staying as close to 60 feet (18 meters) as possible without causing
the Total Ascent Time display to flash. After waiting until the required ceiling
stop depth display indicates 50 FT/ 15 M, you can ascend to, but no shallower
than, 50 feet (15 meters) and continue decompressing. As the required ceiling
stop depth display indicates 40 FT/ 12 M, 30 ft/ 9 M, 20 FT/ 6 M, and then 10
FT/ 3 M, you can ascend to, but no shallower than, the required ceiling stop
depth indicated.
