TABLE 3.2. ASCENT RATE INDICATOR
Ascent Rate The equivalent Example
Indicator ascent speed in Fig.
No segments Below 4 m/min [13 ft/min] 3.8
One segment 4 - 6 m/min [13 – 20 ft/min] 3.9
Two segments 6 - 8 m/min [20 – 26 ft/min] 3.10
Three segments 8 - 10 m/min [26 – 33 ft/min] 3.11
Four segments 10 - 12 m/min [33 – 39 ft/min] 3.12
Four segments, the Above 12 m/min [39 ft/min] or
SLOW segment, continuously above
blinking depth reading, 10 m/min [33 ft/min] 3.13
the STOP sign and
an audible alarm
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 current ascent rate is significantly
above the allowed rate.
Whenever the SLOW warning segment and the STOP sign appear
(Fig. 3.13.), you should immediately 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 (Fig. 3.14.). You should not ascend
shallower than 3 m [10 ft] with the Mandatory Safety Stop warning on.
WARNING!
DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents
increase the risk of injury. You should always make the Mandatory
and Recommended Safety Stops after you have exceeded the max-
imum recommended ascent rate. If this Mandatory Safety Stop is
not completed the decompression model will penalize your next
dive(s).
3.3.6. Decompression dives
When your NO DEC TIME becomes zero, your dive becomes a decom-
pression stop dive, i.e. you must perform one or several decompres-
sion stops on your way to the surface. The NO DEC TIME on your
