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 micro-
bubbles, 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.
