Smart dive computers
I
• 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 com
-
puter! 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
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 4000 m (13000 ft).
• After a dive do not rise to altitudes that the computer prohibits via the flashing altitude
segments (see page 21).
Flying after diving
• After diving, wait at least 24 hours prior to flying.
The Smart PRO and Smart COM dive instruments are personal protective equipment in compliance with
