The acoustic attention messages (but not the alarms) can be switched off
(see page 88).

Attention messages come up in the following situations:
Partial pressure of oxygen reaches limit
The partial pressure of oxygen reaches the set value (to be set not higher than
1.6 bar by MemoMouse and DataTalk-software). See pages 79 and 59.
