3.7 Maintenance of the Microphone Units
• For cleaning the Quinta MU microphone units when they are slightly dirty (finger prints, dust, jam or juice) use a soft, damp cloth, sponge
or brush and mild liquid cleaning agent (e.g. washing-up liquid). Do not use any solvent containing cleaners.
• Make sure not to allow any water to enter the microphone capsule or housing.
• Clean the charging contacts with spirit or isopropyl alcohol from time to time. While cleaning avoid contact with the painted surface.
• Clean the pop shield of the gooseneck microphone for Quinta MU 21/22/23 with clear, warm water. Make sure that it is completely dry be-
fore you put it on the microphone again.
