Cleaning the sound inlet
Pull the sound inlet off of the microphone as shown. Release the inlet either with
your fingers or using a tool with a blunt edge. If several microphones with short
cleaning intervals (e.g. once a week) are used, it is advisable to order a special tool
(Order No. 37 990) from your Sennheiser dealer.
The cleaning intervals are dependent on the degree of contamination. An ultrasonic
bath and Kaltron or similar should be used for cleaning. In the event of severe
contamination or mechanical damage the sound inlet must be replaced with a new
inlet (Order No. 26317: black; 19037: beige).
Before attaching the windscreen, please remove the gauze cap.
