The audible alarm will beep once per second and the Message Box will alter-
nately flash CEILING and VIOLATION until you descend below the required
ceiling stop depth.
As previously described, you would then need to follow the ceiling stop depths
and times toward the surface as the Tissue Loading Bar Graph recedes into
the caution (C.Z.) zone.
2. Your necessary decompression requires a ceiling stop depth be-
tween 60 feet (18 meters) and 70 feet (21 meters).
In this situation the Audible Alarm will emit One Long Beep, the Tissue Load-
ing Bar Graph will flash, and the Message Box alternately flashes EXCEEDED
and CEILING (Fig. 95) four times. 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 Message Box 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.
