– On any given dive, all divers in a buddy group must follow the most conservative dive computer for that
particular dive.
– If the Aladin
®
Air Z fails at any time during the dive, the dive must be terminated, and appropriate sur-
facing procedures should be initiated immediately.
– You MUST follow the ascent rates as indicated by the Aladin
®
Air Z and if the computer should fail for
any reason, you must ascend at a rate of no greater than 10 metres per minute.
– You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin
®
Air Z! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symptoms
occur after a dive! There is a direct correlation between the effectiveness of treatment and the delay bet-
ween the onset of symptoms and the treatment for decompression sickness.
– Always observe the visual and acoustic alarm signals of the Aladin
®
Air Z. Avoid situations of increased
risk which are marked with a warning sign in this operating manual.
– Avoid repeated ascents and descents (yo-yo diving).
– Avoid exertion at depth
– Plan shorter duration for dives in cold water
– After completion of the decompression or at the end of no-stop dives, ascend the last metres to the sur-
face very slowly.
– Ensure that you have enough Air for the Ascent. Do not use the RBT to the limit if prolonged ascents or
an increased rate of breathing (currents…) are expected.
1.3 Minimizing risks on repetitive dives
There is still excess nitrogen in the body due to the history of the preceding dives. Depending on the dura-
tion of the surface interval, there may even be gaseous nitrogen (microbubbles). You can minimize the risk
by observing certain rules:
– observe the same rules for repetitive dives as on your first dive
– plan repetitive dives at a smaller depth than the first dive
– plan a sufficient duration of the surface interval (min. 3- 4 hours)
–
only go on r
epetitive dives, if no indication <Atn> is visible on the display
– plan a day without diving once a week
– repetitive dives after exchanging the dive computer: Wait at least 24 hour before you start with the repe-
titive dive.
