5.9. Activation and pre-checks

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.

5.9.1. Accessing DIVE mode

The Suunto Cobra3 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.

5.9.2. DIVE mode activation

The dive computer activates automatically when submerged deeper than 0.5 m/1.5 ft.

However, it is necessary to activate the DIVE mode BEFORE diving to check the altitude and personal adjustment settings, battery condition, oxygen settings etc.

After activation, all graphical display elements are turned on, and the backlight and the beep are activated. After this, the selected altitude and personal settings are displayed, as well as the RGBM and Deep Stop status. A few seconds later the battery power indicator is shown.

At this time, perform your pre-checks, making sure that:

•the instrument operates in the correct mode and provides a complete display (AIR/NITROX/GAUGE mode)

•the battery level is ok

•the altitude, personal adjustment, Safety/Deep stops, and RGBM settings are correct

•the instrument displays correct units of measurement (Metric/Imperial)

•the instrument displays the correct temperature and depth (0.0 m/0 ft)

•the alarm beeps

And, if set to NITROX mode, make sure that:

•the correct number of mixes is set and that the oxygen percentages are adjusted according to the measured nitrox blends in your cylinders
