Red Zone– As all of the bars appear (red zone), your no-decompression stop time
has become zero and your dive has become a decompression stop dive (for more
information see Section 6.1.5. Decompression dives).
6.1.4. Ascent rate indicator
The ascent rate is displayed graphically along the right hand side with a vertical bar.
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.
