BEA 040

If soiled, clean the housing with a mild cleaning agent.
5.1.2 Combi sensor
!
To guard against destruction of the sealing
diaphragm and the microphone, never use a pointed
object to clean the sound inlets or direct a jet of
compressed air right into the sound inlets.
To ensure proper recording of the structure-borne
sound signal, there must be neither swarf nor dirt on
the magnetic base. The magnetic base can be cleaned
using a mild cleaning agent.
The microphone openings for air-borne sound recording
(Fig. 2, item 1) must never be obstructed. Passing a
gentle flow of compressed air over the sensor surface
is a suitable means of extracting dirt from the sound
inlets.
