The BlaCK eanX, like any other electronic device, may fail during a dive. we
strongly advise against performing no-decompression dives with the use of
only one device for measuring time and depth. note that all recognized diving
federations prohibit performing decompression dives with the use of only one
device that ensures correctly performing the decompression.
If the device fails during a no-decompression dive, it is necessary to start as-
cending immediately at a speed of 10m/min up to the depth of 3-6m, and then
stay there for the max. amount of time depending on the available gas reserve
(taking into account the amount of gas needed to ascend to the surface). after
such emergency ascent it is not advisable to dive within the next 48h.
If the device fails during the dive with required decompression (diving outside
no-decompression limits), you must use the redundant device to calculate the
necessary decompression time, and/or devices to measure the time and depth
and earlier prepared diving plan (runtime) or decompression tables, and then
perform decompression according to their recommendations.
DIVING – HANDLING EMERGENCY SITU-
ATIONS
attention! The above mentioned procedure takes into account
diving within no-decompression limits (nDl). never exceed no-
decompression limit, if you’re not adequately prepared, including
obtaining a proper training for technical diving and the equipment
configuration required for such dives with redundancy of compo-
nents critical for your safety.
You may set the bearing before the dive when necessary. In order to set the
bearing on the surface, select function „set bearing” from the main menu, and
then direct the bearing line to the object which you want to reach or direct the
device on the required course reading its value displayed on the screen. Then
save the bearing holding the right button. The bearing saved will be visible on
the compass scale as a round point and as a numerical value in the right upper
corner of the screen.
after setting the bearing it is necessary to check if it matches the course
which you want to follow. If there is a need to correct, the procedure canbe
repeated and again the device should be directed to the required course press-
ing the right button.
after setting the required bearing it is necessary to leave the main menu by
holding the left button.
