Owner's Manual

For technical dives, you must have the dive plan created and available on the dive
e.g., on a slate. You must also have a back-up plan for lost gases. In the unlikely event
that the dive computer malfunctions during a dive, start using an alternative depth
gauge and timer and following the ascent schedule and gas switches that are on your
slate.
5.3. Dive computer limitations
While the dive computer is based on current decompression research and technology,
you must realize that the computer cannot monitor the actual physiological functions
of an individual diver. All decompression schedules currently known to the authors,
including the U.S. Navy Tables, are based on theoretical mathematical models, which
are intended to serve as a guide to reduce the probability of decompression sickness.
5.4. Audible and visual alarms
The dive computer has audible and visual alarms that advise when important limits
are approached or that prompt you to acknowledge preset alarms. The table below
describes the different alarms and their meanings.
