Descending by more than 0.5m/2ft below
the PDIS or ascending by more than
3m/10ft above the PDIS follows the same
rules as described in the NO-STOP case.

PDIS during dives with MB
levels
When diving with MB levels, PDIS follows
the same rules as described above. MB
levels, however, introduce stops earlier
and deeper than the L0 base algorithm. As
such, the PDIS display may be delayed and
for certain dives it may not be displayed at
all. This for instance would be the case for a
shallow dive with air (21% oxygen) and MB
level L5.
