5.8.2. 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 cylinder pressure, altitude and personal adjustment settings, battery condi-
tion, oxygen settings, and so on. Press the SMART (On) button to activate the in-
strument.
Figure 5.5. Startup I. All segments shown.
After activation, all display elements will turn on showing mostly figure 8’s and graph-
ical elements. A few seconds later the battery power indicator is shown, and the
backlight and the buzzer are activated. If set to Air mode, the screen will enter the
Surface mode. If set to Gauge mode, the text GAUGE is shown, and if set to Nitrox
mode, the essential oxygen parameters are shown with the text "NITROX" before the
Surface mode.
