To change the acoustic filters proceed as follows:
a. First of all remove the ear tips (foam
or silicone) by holding them in the middle
and pulling them slowly until they come
loose.
b. Remove the filter from the earpiece by
pushing the changing tool with the split
end into the used acoustic filter until you
hear a “click” and pull the used filter
straight out.
Preferably use the split end of the
changing tool to change filters.
c. Dispose of any soiled or damaged
acoustic filters. To reuse the filter
in the future, insert it straight in an
empty slot in the filter box, then tip the
changing tool sideways and remove it.
d. To place a new acoustic filter in the
earphones, press the split end of the
changing tool into the filter ring and
gently pull it out vertically.
