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
22
For safety reasons, the backlight cannot be activated when the low
battery warning is indicated by the battery symbol.
