Changing the microphone head
#
First remove the batteries/accupack as described above and leave the
radiomicrophone open.
#
Unscrew the sound inlet basket.
#
Loosen the screw and put it to one side.
#
Gently ease the capsule out of the contacts and then pull it out of the hou-
sing 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 micro-
phone 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).
