7.2. Dive numbering
Several repetitive dives are considered to belong to the same repetitive dive series
when the dive computer has not counted the no-fly time to zero. Within each series,
the dives are given individual numbers. The first dive of the series will be numbered
as DIVE 1, the second as DIVE 2, the third as DIVE 3, and so on.
If you start a new dive with less than five (5) minutes of surface interval time, the dive
computer interprets this as a continuation of the previous dive and the dives are con-
sidered to be the same. The diving display will return, the dive number will remain
unchanged, and the dive time will begin where it left off. After five (5) minutes on the
surface, subsequent dives are, by definition, repetitive. The dive counter displayed in
the Planning mode will increment to the next number if another dive is made.
7.3. Flying after diving
In the DIVE mode, the no-fly time is displayed in the center window next to the airplane
image. In the TIME mode, the airplane image is shown in the top left corner. Flying
or traveling to a higher altitude should be avoided at any time when the computer is
counting down the no-fly time.
NOTE
The airplane symbol is not shown on the stand-by display. You
should always activate the dive computer and check that the air-
plane symbol is not displayed prior to flying.
The no-fly time is always at least 12 hours, or equivalent to the so-called desaturation
time (if longer than 12 hours).
In the Permanent Error mode and GAUGE mode, the no-fly time is 48 hours.
The Divers Alert Network (DAN) recommends the following on no-fly times:
