)
The tolerable partial pressure of oxygen can be set by means of a MemoMouse

Messages:
Depending on the mixture used and the setting of the maximum
ppO
2
the limit for an attention message is reached at different
depths. When the set maximum partial pressure is reached
Aladin

Pro Ultra sends an acoustic attention message and the
current depth display starts flashing.
Response:
Go to a smaller depth in order to diminish the danger of oxygen
intoxication.
The allowed maximum depth should not be exceeded or only for a short
period. Disregarding the warning can lead to oxygen intoxication.
