Sennheiser SKM 500 G2 Instructions For Use Manual page 43

Gently ease the capsule out of the contacts and then pull
it out of the housing as shown. Do not touch the
contacts and the diaphragm!
Insert the new capsule.
Secure the capsule by tightening the screw.
Note:
The screw mechanically secures the microphone capsule.
If the screw is missing, malfunctions may occur during
tough use.
Put on the sound inlet basket and identification ring
supplied with the new microphone head (NB: do NOT use
the old basket, as the different heads use slightly
differing internal foam) and screw it tight.
Insert the batteries/accupack.
Close the radiomicrophone and put it into operation.
Note:
Microphone capsule, sound inlet basket and foam insert
form an acoustic unit and must therefore always be
exchanged all together. Each microphone head comes
with a color-coded identification ring to distinguish
different microphone heads from each other (green =
MD 835, blue = MD 845, red = ME 865).
