Messages: An acoustic signal is sent if oxygen toxicity reaches 75%. The
symbol <CNS O
2
LIMIT> flashes continuously. The ascent arrow
and the O
2
-alarm-triangle is shown.
Response: Go to a smaller depth if necessary.
Messages: When oxygen toxicity reaches 100%, an acoustic alarm is sent
every 4 seconds. Also CNS O
2
% value, the ascent arrow and
the O
2
-alarm-triangle are flash continuously. See also page 79.
Response: Start ascent at once.
– During an ascent and if the CNS O
2
% value does not increase
anymore (due to a lower partial pressure of oxygen), the acous-
tic warning and the ascent arrow are suppressed.
– During the ascent, the display of the oxygen toxicity extinguishes
and the ascent rate is displayed. If the ascent is stopped, the dis-
play changes back to the indication of oxygen toxicity.
