Smart dive computers
I
• Always dive with back-up instruments. Make sure that you always use back-up instrumentation inclu-
ding 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 Smart TEC!
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.
• 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 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 Smart TEC prohibits via the flashing altitude
segments. (->25)
Flying after diving
• After diving, wait at least 24 hours prior to flying.
Smart TEC dive instrument is a personal protective equipment in compliance with the essential safety
requirements of the European Union directive 89/686/EEC. RINA SpA, Via Corsica 12, I-16128 Genoa,
notified body no. 0474, have certified the conformity with the European Standard EN 250:2000 and EN
13319:2000.
EN250:2000 Respiratory equipment - Open circuit self contained compressed air diving apparatus -
Requirements, testing, marking (pressure gauge test).
EN13319:2000 Diving accessories - Depth gauges and combined depth and time measuring devices -
Functional and safety requirements, test methods. Any information on decompression obligation display-
ed by equipment covered by this standard is explicitly excluded from its scope.
