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 feet after this message.
It is dangerous and unsafe diving practice to push
a dive computer 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 feet is displayed. Beside the decompression depth, the decom-
pression time of the displayed stage in minutes appears. The display <10ft 5:>
means that a decompression stop of 5 minutes at a depth of 10 feet 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 decompression 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. continue page 63
