SCUBAPRO MERIDIAN
CNS O
2
reaches 100%, Meridian will emit a
sequence of audible beeps for 12 seconds
and the value of the CNS O
2
will be flashing
in the lower right corner. The flashing will
continue until the value of CNS O
2
drops
under 100%.
CNS O
2
= 100%
The audible signal is repeated for 5
seconds in one minute intervals after the
first occurrence and for as long as the value
of CNS O
2
stays at or above 100% or until
the ppO
2
drops under 0.5bar (see chapter
3.10 Diving with nitrox or with another
decompression gas for a list of depths at
which ppO
2
equals 0.5bar for some typical
Nitrox mixes).
3.11.10 Missed decompression stop
WARNING
Violating a mandatory decompression
obligation may result in serious injury or death.
Omitted deco stop
If in presence of a required decompression
stop you ascend more than 0.5m/2ft above
the required stop, Meridian will trigger an
alarm: the value of the current depth and
the value of the required stop depth will
flash, and a sequence of beeps can be
heard. This will continue for as long as you
stay 0.5m/2ft or more above the required
stop.
3.11.11 Low battery
WARNING
Do not start a dive if the battery symbol
is displayed flashing on the screen on the
surface. The dive computer may fail to function
during the dive and this could lead to serious
injury or death.
During the dive, Meridian alerts you of
precarious battery situations in two ways:
By displaying a steady battery symbol on
the screen. This means you can finish the
dive but you should replace the battery
once you return to the surface;
By displaying a flashing battery symbol on
the screen. This means you need to start
the procedure to terminate the dive, as
there is not enough energy in the battery
to ensure proper continued functioning and
the dive computer may fail. If the battery
symbol is flashing, the backlight cannot
be activated and the audible warnings and
alarms are not available anymore.
3.11.12 Setting bookmarks
By press and hold LIGHT button you can
set any number of bookmarks as reminders
of particular moments during the dive. The
bookmarks will appear on the dive profile
in JavaTRAK.
3.11.13 Safety stop timer
If a minimum depth of 10m/30ft has
been reached during the dive, at a depth
of 5m/15ft the safety stop timer will
automatically start a countdown. If you go
below 6.5m/20ft, the timer will disappear
and the no-stop time is shown again. Upon
returning to 5m/15ft, the timer will start
again automatically. As long as you are
