Safety considerations
• Comply with the ascent rate and carry out any decompression stop required. If the computer
should fail for any reason, you must ascend at a rate of 10m (30 feet) per minute or less.
• On any given dive, both divers in a buddy pair must follow the most conservative dive computer
for that particular dive.
• Never dive without a buddy. XP AIR does not substitute for a dive buddy.
• Only make dives that are appropriate to your level of dive training. A dive computer does not
increase your knowledge of diving.
• Always dive with back-up instruments. Make sure that you always use back-up instrumentation
including a depth gauge, submersible pressure gauge, digital bottom timer or dive watch, and
have access to decompression tables whenever diving with a dive computer.
• Avoid repeated ascents and descents (yo yo diving).
• Avoid repeated heavy workload while at depth.
• Plan the dives to be shorter if they are made in cold water.
• After finishing the decompression or at the end of a no-stop dive, the final stage of the ascent
should be as slow as possible.
• You MUST be familiar with all signs and symptoms of decompression sickness before using
this computer! 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 between the onset of symptoms and the treatment for decompression
sickness.
• Only dive with Nitrox after you have been thoroughly instructed by a recognised institution.
Repetitive dives
• Do not start your next dive before your CNS O
2
% status has dropped below 40%.
• Diving with Nitrox: Make sure your surface interval is long enough (just like diving with
compressed air). Plan for a minimum surface interval of two hours. Oxygen, too, needs sufficient
time to leave the body.
• Match gas mixture to the intended dive.
• Do not attempt a repetitive dive if the microbubble warning
NO
is visible on the display.
• Plan a day without diving once a week.
• If you have to change computers, wait at least 48 hours before carrying out your next dive.
Altitude and diving
• Do not dive at altitudes higher than 4000m (13000 feet).
• After a dive do not rise to altitudes that the computer prohibits via the flashing altitude
segments (see page 26).
Flying after diving
• After diving, wait at least 24 hours prior to flying.
