VIII Trouble Shooting
symptom possible reason(s) procedure(s)
Check meteorological information.
Send in dive computer for servicing
(only if altitude section is wrong by
more
than one section, see chapter III 6).
Study 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. Study 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.
Air pressure measured by the computer
is wrong.
Slow tissue and/or little workload at the
surface.
Many repetitive dives, yoyo-diving or
disregard of decompression stops have
caused a large number of microbubbles,
which have to decrease first.
Many repetitive dives, too fast ascents,
yoyo-diving or disregard of decom-
pression stops have caused a large
number of microbubbles, which have
to decrease first.
