mostly fi gure 8’s and graphical elements (Fig. 3.1.). A
few seconds later the battery power indicator is shown
and the backlight and the buzzer are activated (Fig. 3.2.
display a, b, c or d depending on the battery voltage). If
set to Air mode the screen will enter the Surface mode
(Fig. 3.3.). If set to Gauge mode the text GAUGE is
shown (Fig. 3.4.) and if set to Nitrox mode the essential
oxygen parameters are shown with the text NITROX
