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
condition, oxygen settings etc. Press the
SMART (Mode) button to activate the in-
strument.
After activation all display elements will turn
on showing mostly figure 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 essen-
tial oxygen parameters are shown with the
text NITROX (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
and RGBM settings are correct
