6.2.1. Before diving in NITROX mode

If set to the NITROX mode, the correct oxygen percentage of the gas in your cylinder

must always be entered into the computer to ensure correct nitrogen and oxygen

calculations. The dive computer adjusts its mathematical nitrogen and oxygen

calculation models accordingly. The dive computer will not accept fractional percentage

values of oxygen concentration. Do not round up fractional percentages. For example,

31.8% oxygen should be entered as 31%. Rounding up will cause nitrogen percentages

to be understated and will affect decompression calculations. If you want to adjust the

computer to provide more conservative calculations, use the personal adjustment

feature to affect decompression calculations, or reduce the PO

setting to affect oxygen

exposure according to the entered O

% and PO

values. Calculations based on nitrox

use result in longer no-decompression times and shallower maximum depths than

diving with air.

As a safety precaution, the oxygen calculations in the computer are made with an

oxygen percentage of 1% + set O

% .

When the dive computer is set in NITROX mode, the Dive Planning mode calculates

using the O

% and PO

values that are currently in the computer.

To set the nitrox mixes, refer to Section 5.8.3. Setting the nitrox values.

Default nitrox settings

In NITROX mode, the Suunto D6 allows you to set 1 or 2 nitrox mixes containing 21-

99% oxygen.
