VIII Trouble Shooting
The logbook does not
show any air consump-
tion (dp) for a certain
dive.
Altitude section does
not correspond to the
current altitude.
Desaturation time and/
or no fly time are very
long.
<Atn> appears
An unexpected decom-
pression stop appears in
place of no-stop time or
decompression increa-
ses in leaps.
No tank pressure signal was received
at the beginning or end of the dive.
Transmitter and dive computer were
not paired before the dive started.
Atmospheric pressure is especially
high or low.
Air pressure measured by the compu-
ter 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 decrea-
se first.
Many repetitive dives, too fast
ascents, yoyo-diving or disregard of
decompression stops have caused a
large number of microbubbles, which
have to decrease first.
Too rapid ascent or ignoring decom-
pression stops have caused a large
number of microbubbles, which
leads to an attention message (war-
ning of bubbles).
Mount transmitter correctly
(see chapter II 4).
Pair transmitter and computer
(see chapter II 4).
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 chap-
ters III 5 and IV very carefully.

and dives at lower risk. Study chap-
ters III 5 and IV very carefully.
