4 Functions during the dive with microbubble levels
UWATEC
®

V
The attention message "
Level stop ignored
" is
activated if the requested level stop is not observed.
An attention beep* goes off, the arrow
LEVELSTOP
,
the depth and duration of the ignored level stop
begin flashing.
To complete the dive without being reduced to a
lower MB level, you must descend to the prescribed
depth immediately!
The warning "
microbubble level reduced
" is
activated if the diver ascends more than 1.5m (5ft)
above the required level stop. Smart Z reduces the
microbubble level, an attention beep* goes off and
for the rest of the dive the new MB level is indicated
in the position of O
2
% mix. The level stop for the
reduced MB level is now displayed.
To complete the dive without being further reduced
to an even lower MB level the new level stop must
be observed.
* Attention beeps can be suppressed via SmartTRAK.

4.2 Total time of ascent
Smart Z displays the level stop information and the total time of ascent. This
includes the time of ascent as well as all level stops.
The total time of ascent is calculated on the basis of the prescri-
bed ascent rate and a normal workload. Total time of ascent can be
subject to change if the ascent rate is not ideal (100%) or if Smart Z
detects a higher workload.
4.3 Decompression obligation
Avoid decompression dives when diving with MB
levels.
Smart Z calculates and displays level stops to reduce microbubble formation,
but it also calculates the diver's decompression data. If decompression stops
become obligatory, the
DECO
symbol will be displayed. The total ascent time will
now also contain a decompression stop.
You are close to entering decompression: At the
beginning of a decompression phase an attention
beep goes off and the
DECO
symbol flashes for 8
seconds.
In order to prevent a dive with long decompression
stops it is recommended that you ascend a few
metres/feet on seeing this message.
