Suunto Cobra2 [22/56] Dive mode activation

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 display elements turn on showing mostly figure 8s and graphical

elements, 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

•

the oxygen partial pressure limits are set correctly

For more information on the NITROX mode, refer to Section 6.2. Diving in NITROX mode

(DIVEnitrox).

The dive computer is now ready for diving.

5.9.3. Battery power indication

Temperature or internal oxidation of the battery affect the battery voltage. If the instrument

is stored for a long period, or used in cold temperatures, the low battery warning may be

displayed even though the battery has enough capacity. In these cases, re-enter DIVE

mode to receive the battery power indication.

After the battery check, the Low Battery Warning is indicated by the battery symbol.

If the battery symbol is displayed in the Surface mode, or if the display is faded or weak,

the battery may be too low to operate the dive computer, and battery replacement is

recommended.

NOTE

For safety reasons, the backlight cannot be activated when the low

battery warning is indicated by the battery symbol.
