During the decompression stop, ASC TIME will count down towards zero. When the ceiling
moves upwards, you can ascend to the new ceiling. You may surface only after the ASC
TIME and CEILING labels have disappeared, which means that the decompression stop
and any Mandatory Safety Stop have been completed. You are advised, however, to stay
until the STOP sign has also disappeared. This indicates that the three minute Recommen-
ded Safety Stop has also been completed.
