Messages:
There is an acoustic signal if no-stop time is less than 1 minute. In
this last minute, the no-stop display shows the flashing value <0>.
Response:
In order to prevent a decompression dive, you must ascend a few
metres after this message.
It is dangerous and unsafe diving practice to push a dive com-
puter or any other decompression tool to its limits. Avoid no-
stop times of less than three minutes at any given depth.
Decompression values
On entering the decompression phase, the arrow <NO STOP> disappears. The
arrow <DECOSTOP> appears. Right beside the arrow, the deepest decompres-
sion stage in metres is displayed. Beside the decompression depth, the decom-
pression time is displayed in minutes for this stage. The display <3m7:> means
that a decompression stop of 7 minutes at a depth of 3 metres has to be made.
When a decompression stop has been finished, the next higher decompression
stop is displayed. When all decompression stops have been made, the arrow
<DECOSTOP> extinguishes and the arrow <NO STOP> reappears. The indi-
cation of time on the lower right shows the no-stop time again.
Messages:
The decompression alarm is activated if the decompression
stop is ignored. The arrow <DECOSTOP> begins flashing and
an acoustic alarm is initiated. Due to the formation of micro-
bubbles decompression can increase massively if a decom-
pression stop is ignored. When the surface is reached during
the decompression alarm, the arrow <DECOSTOP> continues
flashing, in order to point to the risk of a decompression
accident. The SOS-mode is activated 3 minutes after the dive if
corrective action is not taken.
If the total (cumulative) duration of the decompression alarm
is longer than a minute, it is entered in the logbook.
