Diving with XP AIR
!
WARNING
Never allow the RBT to go below three minutes. If the RBT goes below three minutes there
is a danger of insufficient supply of gas mixture for the ascent as well as an increased risk of
decompression sickness, and serious injury or death may result!
Correct calculation of RBT when using a reserve or “J“ type valve is possible only if the reserve
function of the valve is in the open (down) position during the dive.
!
WARNING
If the RBT drops below three minutes, an audible attention signal
is activated, the ascent arrow is displayed and the tank icon start
flashing.
Start ascent immediately.
!
WARNING
The RBT value should never reach "0:". With RBT=0 the remaining
tank reserve may not be sufficient for the ascent.
When the last minute has passed (RBT=0) an audible alarm is activated
every 4 seconds. The RBT, the ascent arrow and the tank icon start
flashing. The audible alarm on exceeding the RBT is suppressed at
depths less than 6.5 m (21 ft) if XP AIR is in the no-stop phase.
Start ascent at once.
Start ascent immediately.
4.11 Decompression information
No-stop time is displayed if no decompression stops are necessary. The arrow
NO STOP
is visible if no
decompression stops are necessary. The figures indicate no-stop time in minutes.
F
•
No-stop display "99:" means remaining time of 99 minutes or more.
• No-stop time is calculated on line and influenced by the current
workload and current water temperature
!
WARNING
If no-stop time drops below 3 minutes, an audible attention signal is
activated and the no-stop value begins to flash.
If no-stop time is less than 1 minute, the no-stop display shows the
flashing value "0".
In order to prevent a decompression dive, ascend slowly until the
no-stop time is 5 minutes or more.
!
WARNING
Dives that require decompression stops are not recommended.
