Sport Plus expects your input for the duration of the dive interval.
4a
If no surface interval is to be entered, (diving at the present moment), con-
firm this with contacts B and E, and you switch into no-stop planning.
4b
You can extend the interval with contacts B and E.
B and – shorten the interval.
5
You confirm the new surface interval and get into no-stop planning.
After confirming the surface interval (if possible), no-stop times are displayed
in 10-ft-increments. The process starts with the plan depth of the no-stop
time which must be shorter than 99 minutes. The no-stop time for every 10-
ft-increment is displayed for about 3 seconds (scrolling no-stop times).
Repetitive dives usually cause more microbubbles in the lungs than first dives
if the surface interval is not long enough. Too rapid an ascent and/or disre-
garding decompression instructions can lead to microbubbles. By calculating
the formation of bubbles, Aladin
®
Sport Plus is able to advise the diver to
extend the surface interval if necessary. If <Atn> is displayed instead of the
depth in addition to the no-stop times, the diver should plan an extension of
the interval if possible.
By repeated recallings of the diveplan with varying surface intervals the mini-
mum interval can be determined.
