Setting bookmarks
By press and hold the “LIGHT” button
you can set any number of bookmarks as
reminders of particular moments during the
dive. The bookmarks will appear on the
dive profi le in SCUBAPRO LogTRAK.
4.7.1.4
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 3-minute 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.
4.7.1.5
Activating the backlight
To activate the backlight,
press LIGHT
.
The duration of the backlight is 10 seconds.
Note: The backlight is not available when
the
BATTERY CHANGE
warning appears.
4.7.1.6
Diving with MB levels
Microbubbles are tiny bubbles that can
build up inside a diver’s body during any
dive and normally dissipate naturally during
an ascent and on the surface after a dive.
Dives within no-stop time and observance
of decompression stops do not prevent the
formation of microbubbles in the venous
blood circulation. Chromis has been
equipped with an enhanced SCUBAPRO
algorithm, named ZH-L8 ADT MB, to reduce
the formation of these microbubbles.
This enhanced algorithm allows the user
to choose a level of conservatism over and
in addition to the worldwide proven safety
record of the standard ZH-L8 ADT algorithm.
There are fi ve levels of added conservatism
(or MB levels), from L1 to L5, with L5 being
the most conservative and L1 being just a bit
more conservative than the standard ZH-L8
ADT, here referred to as L0.
Choosing an MB level between L1 and L5
makes the algorithm more conservative,
therefore the diver will have either shorter
no-stop times or deeper and longer
decompression stops than when diving
with L0. Consequently the body will either
take up less nitrogen (shorter no-stop
dives) or will be able to off-gas more before
returning to the surface (dives with L1..L5).
Both work towards reducing the amount
of microbubbles present in the body at the
end of the dive.
Please refer to chapter
Setting the Micro
Bubble
level for information on setting the
MB level.
For easier understanding underwater,
Chromis handles MB level stops as
decompression stops. If you select
to use a MB level you must follow the
consequent ascent plan.
