This section describes how to activate the DIVE mode and explains the pre-checks that it is highly recommended you perform before you get into the water.

5.10.1. Accessing DIVE mode

The Suunto D9 has three diving modes: AIR mode for diving with standard air only, NITROX mode for diving with oxygen enriched mixtures, and GAUGE mode for use as a bottom timer and for freediving. The OFF mode disables the DIVE mode, and allows the TIME mode to be used underwater. The chosen dive mode is displayed when the DIVE mode is accessed, and you can toggle between the submodes by pressing the UP/DOWN buttons.
