Diving with microbubble levels
!
WARNING
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!
!
WARNING
The warning "microbubble level reduced" is activated if the diver
ascends more than 1.5m (5ft) above the required level stop. XP AIR
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.
F
* Attention beeps can be suppressed via Dive.Log.
4.2 Total time of ascent
XP AIR 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 prescribed 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 XP AIR detects a higher workload.
4.3 Decompression obligation
!
WARNING
Avoid decompression dives when diving with MB levels.
XP AIR 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.
!
WARNING
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.
