When the maximum allowed ascent rate is exceeded the fifth SLOW warning segment
and the STOP sign appear and the depth reading starts to blink indicating that the
maximum ascent rate has been exceeded continuously or that the ascent rate is above
the allowed maximum rate.
Whenever the SLOW warning segment and the STOP sign appear, you should imme-
diately slow down your ascent. When you reach the depth zone between 6 m to 3 m
/20 ft to 10 ft, the STOP and CEILING depth labels will advise you to make a Mandatory
Safety Stop. Wait until the warning disappears. You should not ascend shallower than
3 m/10 ft with the Mandatory Safety Stop warning on.

shown: ascent rate is more than 10 m/min/33 ft/min. This is a caution to slow down!
The STOP sign means that you are advised to make a Mandatory Safety Stop when
