3.3 BEFORE DIVING

3.3.1 Activation, Prechecks and Battery Warning

The instrument is always ready for use and will activate if submerged. However, it is

necessary to turn it on before diving to check the personal/ altitude adjustment setting,

battery power, etc. This is done, either by immersing it in water for a couple of seconds

or by connecting the PLAN/ON and COM contacts with fingertips.

When deactivated the time display is always shown. Once activated all display ele-

ments will turn on (showing mostly figure 8’s and graphical elements) (Fig. 3.3). A few

seconds later the battery power bar graph is shown (Fig. 3.4). Next, the screen will

alternate between two READY displays, confirming that the activation is complete (Fig.

3.5). At this time, perform your precheck making sure that:

• the dive computer operates and provides a complete display

• the low battery indicator is not on

• the personal/ altitude adjustment setting is correct

The instrument is now ready for diving. If it is not taken on a dive after activation, it will

automatically switch off to the time display in 10 minutes to conserve the battery power.

The dive computer does not need to be reactivated for repetitive dives. It will remain active

until it has calculated that all residual nitrogen has off-gassed. This may take up to 48 hours,

as described in Section 6.1, “Operating Principles”.
