Changing the diaphragm
●
To remove the diaphragm the chest
piece has to be put onto a table
with the diaphragm facing
upwards. With your thumb and
index finger you can roll the rubber
ring aside until it slips over the
edge of the chest piece.
●
To fix the new diaphragm, put the
chest piece onto a table with the
diaphragm-side facing upwards.
Then place the new diaphragm cor-
rectly. Now take the rubber ring and
slip it back again. The easiest way
to do this, is to take the rubber ring
with its thinner brim of the ring
facing downwards. Fix the rubber
ring with your thumb and index fin-
ger in one position and slip the ring
with the thumb of the other hand in
a circular movement. Align the ring
in such a way, that the diaphragm is
held firmly.
