Good day,

thank you very much for your message and the detailed description.

Please find attached the English operating manual for the Air Navigator as well as a short video showing how to change and adjust the working pressure.

Important points to check:

• The system has two authorization levels:

  • Level 2 – Administrator → allows changing settings (e.g. working pressure)

  • Level 5 – User → read-only access (no changes possible)

• Please open Menu → User Administration and log in using the same password.
  There you can see which authorization level is currently active.
  Please note that you can only be logged in to one level at a time.

• Only Admin level (Level 2) allows changing operating parameters such as
  activation and deactivation pressure.
  User level (Level 5) is for viewing all settings only.

If, after reviewing the manual and following the steps shown in the video, you still cannot access administrator mode or change the pressure settings, please reply to this email and ideally send us a short video of the display while performing the same steps shown in our video. This will help us support you more efficiently.

We will be happy to assist you further.
