• The percentage of oxygen (FO2) in the Nitrox mix being used must be 'set
before each nitrox dive', unless the FO2 50% Default feature is set OFF (a user
setting).
• Plan Mode provides predicted times for subsequent dives. Depending on cylin-
der size, breathing gas consumption, and oxygen accumulation, you may have
less time available than indicated because of breathing gas quantity or other
limitations.
• Until it has shut itself off, you must not use the ZEN at a different Altitude than
the Altitude at which it was activated. Doing so will result in an error equal
to the difference in barometric pressure, and possibly a false dive mode with
erroneous data.
• To provide proper Altitude compensation, the ZEN must be manually activated
at the new altitude. Dive computers, such as the ZEN cannot sense changes in
barometric pressure if activated by immersion in water at higher Altitudes.
• Use the Caution Zone of the Nitrogen Bar Graph as a visual reference to pro-
vide a greater margin of protection between you and the No Decompression
Limits.
• Every effort should be made to keep each of the Bar Graphs in the normal zone
throughout your dives to reduce your risk of exposure to decompression sick-
ness, oxygen toxicity, and the effects of excessive ascent rates.
