3. DIVING WITH THE VYTEC
This section contains instructions on how to operate the dive computer and interpret its displays. You will find that this dive computer is easy to use and read. Each display shows only the data relevant to that specific diving situation.
3.1. BEFORE DIVING
3.1.1. Activation and Prechecks
The dive computer will activate if submerged deeper than 0.5 m (1.5 ft). However, it is ne- cessary to turn on the Dive Mode before diving to check the cylinder pressure, altitude and personal adjustment settings, battery condi- tion, oxygen settings etc. Press the SMART (Mode) button to activate the instrument.
After activation all display elements will turn on showing mostly figure 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 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 NI- TROX (Fig. 3.21.) before the Surface mode.
At this time, perform your prechecks making sure that:
•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 are correct
