WARNINGS and SAFETY RECOMMENDATIONS
• The percentage of oxygen (FO2) in the nitrox mix being used must be set 'before each' nitrox
dive, unless the FO2 50% Default is set to 'Off'.
• The Pre Dive Planning Sequence provides predicted times for subsequent dives. Depending
on cylinder size, breathing gas consumption, and oxygen accumulation you may have less
time available than indicated because of breathing gas quantity or other limitations.
• The Pro Plus must be manually activated and be in an operating mode prior to start of a
dive. The unit will not activate automatically by immersion in water.
• Every effort should be made to keep each of the bar graphs in the green throughout your
dives to reduce your risk of exposure to decompression sickness and oxygen toxicity.
• Until it has shut itself off, you must not use the Pro Plus at a different altitude than the alti-
tude where it was originally activated. Doing so will result in an error equal to the differ-
ence in barometric pressure, and possibly a false dive mode with erroneous data.
