3.4. DIVING IN NITROX MODE
3.4.1. Before Diving
The ZOOP can be set for diving with standard air only (Air mode) or it can be set for
diving with Enriched Air Nitrox (Nitrox mode). If you are educated for nitrox diving
and you plan to make nitrox dives, it is recommended that you set the dive computer
permanently to its NITROX Mode. The Nitrox mode can be enabled by accessing
MODE-SET-MODEL (see chapter 4.2. “Set Modes”).
If set to 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
according to the entered O
2
% and PO
2
values. Calculations based on Nitrox use result
in longer no-decompression times and shallower maximum depths than diving with
air. When the dive computer is set in Nitrox mode the Dive Planning modes calculates
with the O
2
% and PO
2
values that are currently in the computer.
WARNING DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU HAVE
NOT PERSONALLY VERIFIED ITS CONTENTS AND ENTERED
THE ANALYSIS VALUE INTO YOUR DIVE COMPUTER! Failure
to verify cylinder contents and enter the appropriate O
2
% into your
dive computer will result in incorrect dive planning information.
WARNING The dive computer will not accept fractional percentage values of
oxygen concentration. Do not round up fractional percentages. For
