symptom
possible reason(s)
response
Check barometric information.
Send in dive computer for servicing
(only if altitude section is wrong by more
than one section, see chapter III 6).Re-
view chapter III 5 very carefully.
Plan sufficiently long surface interval
and dives at lower risk.
Plan sufficiently long surface interval
and dives at lower risk. Review chapters
III 5 and IV very carefully.
Altitude section does not
correspond to the current
altitude.
Desaturation time and/or
no fly time are very long.
<Atn> appears in place of
the diving depth on the
display.
Atmospheric pressure is especially high
or low.
Gas mixture pressure measured by the
computer is wrong.
Slow tissue and/or little workload at the
surface.
Too many repetitive dives, yo-yo-diving,
square profile repetitive dives or disre-
garding decompression stops. Dissolved
nitrogen and/or microbubbles must be
off gassed first.
Too many repetitive dives, too fast
ascents, yo-yo-diving, square profile
repetitive dives or disregarding
decompression stops. Dissolved
nitrogen and/or microbubbles must be
off gassed first.
