Diving with XP AIR
Decompression values
On entering the decompression phase, the arrow
NO STOP
disappears,
the arrow
DECOSTOP
appears and an attention beep goes off. Right beside
the arrow, the deepest decompression stage in metres (feet) is displayed.
Next to the decompression stop depth, the decompression stop duration of
the displayed stage appears in minutes. The display "3m 7:" means that a
decompression stop of 7 minutes at a depth of 3m has to be made.
When a decompression stop has been completed, the next (shallower)
decompression stop is displayed. When all decompression stops have
been completed, the arrow
DECOSTOP
extinguishes and the arrow
NO STOP
reappears. The indication of time on the lower right shows the no-stop time
again.
Deco stop depths deeper than 27m (90 ft) are displayed as "– – : – – ".
!
WARNING
The decompression alarm is activated if the decompression stop is
ignored. The arrow
DECOSTOP
, the decompression stop duration and
decompression stop depth begin to flash and an audible alarm goes off.
Due to the formation of microbubbles, decompression can increase
massively if a decompression stop is ignored. When the surface is
reached during the decompression alarm, the arrow
DECOSTOP
, the
decompression stop duration and decompression stop depth continue
flashing, in order to point to the risk of a decompression accident. The
SOS mode is activated 3 minutes after the dive if corrective action is
not taken (->11).
If the total (cumulative) duration of the decompression alarm is longer
than one minute, it is entered in the logbook.
Descend to the prescribed decompression stop depth immediately!
Total time of ascent
As soon as decompression stops are necessary XP AIR shows the total
time of ascent. This includes the ascent time from the current depth to the
surface and all decompression stop obligations.
F
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.
Ascent time greater than 99 minutes is displayed as "– –".
!
WARNING
On all dives with XP AIR, make a safety stop for at least three minutes
at a depth of 5 m (15 feet).
