The dive computer will activate if submerged

to check the cylinder pressure, altitude and
personal adjustment settings, battery condi-
tion, oxygen settings etc. Press the SMART
(Mode) button to activate the in strument.
After activation all display elements will turn
on showing mostly fi gure 8’s and graphi-
cal elements (Fig. 3.1.). A few seconds later
the battery power indicator is shown and
the backlight and the buzzer are acti vated
(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 NI-
TROX (Fig. 3.21.) before the Surface mode.
At this time, perform your prechecks making

• the instrument operates in the correct
mode and provides a complete display
(Air/Nitrox/Gauge modes)
• the low battery indicator is not on
• the altitude, personal adjustment,
RGBM and safety/deep stops settings
