Moisture Shield; Cleaning; Surfaces; Handheld Transmitter Internal Windscreen - AKG WMS 40 PRO FLEXX User Instructions

A special moisture shield on the microphone capsule makes it difficult for moisture and makeup to pen-
etrate into the microphone. This barrier prevents the microphone sound entries from being clogged by
perspiration or makeup, which would make the sound dull and reduce the sensitivity of the microphone.
Therefore, never remove the moisture shield from the microphone!
In case the moisture shield is damaged or lost, the C 444 L head-worn microphone includes two replace-
ment moisture shields.
• Use a soft cloth moistened with water to clean the receiver and transmitter surfaces.
1. Unscrew the wire-mesh cap of the handheld transmitter CCW and remove the wire-mesh cap from
the transmitter.
2. Remove the windscreen (foam sheet) from the wire-mesh cap.
3. Wash the windscreen in mild soap suds.
4. As soon as the windscreen has dried, replace it in the wire-mesh cap and screw the wire-mesh cap
onto the transmitter CW.
