[. . . ] The headset is capable of producing sound pressure levels exceeding 85 dB(A). In many countries 85 dB(A) is the maximum legally permissible level for continuous noise exposure during the working day. Exposure to sounds of higher volume levels or for longer durations can permanently damage your hearing! [. . . ] You can change the microphone sensitivity by turning a small screwdriver in the direction of the arrow. + ­ 7 Care and maintenance Cleaning the headset Use a soft, slightly damp cloth to clean the headset from time to time. If the headset is very dirty, use a cloth dampened with mild, soapy water. Water entering the housing of the headset can cause a short-circuit and damage the electronics.

Grasp the edge of the foam earpad behind the earcup as shown and peel it up and away from the earcup. Repeat for the other earcup. 8 Accessories and spare parts By changing the cable, you can simply retrofit your headset (see "Product variants" on page 11).
