on Nitrox use result in longer no-decompression times and shallower maximum depths than div- ing with air.

As a safety precaution the oxygen calculations in the computer are made with an oxygen per- centage of 1% + setO2% .

When the dive computer is set in Nitrox mode the Dive Planning and Dive Simulation modes both calculate with the O2% and PO2 values that are currently in the computer.

To set the Nitrox mixes refer to chapter 4.3 Set Modes.

DEFAULT NITROX SETTINGS

In Nitrox mode the Vytec allows the user to set 1-3 nitrox mixes containing 21-99% oxygen.

In the Nitrox mode, the default setting for MIX1 is standard air (21% O2). It remains in this setting until the O2% is adjusted to any other percentage of oxygen (22% - 100%). The default setting for maxi- mum oxygen partial pressure is 1.4 bar, however you are able to set it in the range of 0.5 - 1.6 bar.

If unused, the computer will retain the manually entered values for the oxygen percentage and maximum oxygen partial pressure for MIX1 for about two hours, after which it will revert to the default settings.

MIX2 and MIX3 are by default set to OFF. To set MIX2 and MIX 3 refer to chapter 3.4.4 Gas change and multiple breathing mixes. Oxygen percentages and maximum oxygen partial pres- sures for MIX2 and MIX3 are stored permanent- ly. If MIX2 and MIX3 are set OFF, the computer will retain the manually entered values for the oxygen percentage and maximum oxygen par- tial pressure for MIX1 for about two hours, after which it will revert to the default settings.
