ALADIN H USER MANUAL
The PDIS depth is shown in the lower left
corner, with the PDIS icon. During a no-
stop dive, as soon as you reach that depth
during an ascent, a 2-minute countdown
will appear in place of the no-stop value
with the label STOP. In addition, the PDIS
label will blink. You can have one of 3
situations:
PDIS completed
Normal MB level stop
• You have spent 2 minutes within
3m/10ft above the indicated depth.
The countdown timer disappears and
the PDIS value is replaced by the label
YES as an indication that you have
performed the PDI stop.
• You have descended more than
0.5m/2ft below the PDIS. The
countdown timer disappears and will
reappear again, starting at 2 minutes,
the next time you ascend to the PDIS
depth.
• You have ascended more than 3m/10ft
above the PDIS. The PDIS value and
countdown timer are replaced by the
label NO to indicate the fact that you
have not performed the PDI stop.
If the Aladin H is displaying a decompression
obligation when you reach the PDIS depth
during an ascent, all rules apply the same
way, but the 2-minute countdown runs in
the background and is not displayed on the
screen. The PDIS label, however, will still be
blinking, indicating that you are in the PDIS
range.

NOTE: The Aladin H issues no
warnings relating to a missed PDI
stop.
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 example, would be the case for
a shallow dive with air (21% oxygen) and
MB level L5.
