D: How to Exchange the Wax Protection Filter on Your
Speaker Unit
The wax filter in the speaker unit should be replaced
when clogged or when the hearing aid does not sound
normal. Use the wax filter delivered by your hearing care
professional.
E: How to Clean the Microphone Openings
Make sure that the microphone openings are not clogged
by dust or dirt. Carefully brush away visible signs of
debris from the openings. Brush only on the surface and
make sure the hairs of the brush are not pressed into the
openings. Be careful not to push debris into the
microphone openings, as this can affect the
performance of the hearing aid.
