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 30 feet 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 optical 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.
• Never dive the Aladin
®
Air Z to the limits. Neither the Aladin
®
Air Z nor any other diving computer or
decompression table should be pushed to its limits. Give yourself a margin of safety by always leaving
at least a few minutes in the “no-stop“ box before making your ascent.
• Avoid repeated ascents and descents (yo-yo diving) while using the Aladin
®
Air Z.
• 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 feet 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.
1.2 Minimizing risks on repetitive dives
With consecutive repetitive dives, there will be excess nitrogen in the body due to the accumulation of
nitrogen on the preceding dives. Depending on the length of the surface interval, there could even be
gaseous nitrogen (microbubbles) in your body. This accumulation of both soluble as well as potentially
gaseous nitrogen in the body can greatly increase the risk of decompression sickness on subsequent dives.
That risk can be minimized.
• Observe the same rules for repetitive dives as on your first dive
• Always make your first dive the deepest dive of the day.
• Always make the deepest descent of each given dive on a particular day at the beginning of that dive.
