Changing the microphone filter
The two microphones on the back of your hearing aid are protected by a microphone filter. If you experience
sound deterioration or increased difficulty identifying where the sounds come from, changing the filters may help.
You will need a box of microphone filters. Contact your hearing
care professional.
The microphone filter tool has two functions: a removal tip to
collect the used filter, and a replacement tip with a new filter.
Box of 8 microphone filter tools.
Removing the old microphone filter
1. Open the filter case and take out one of the tools. Each tool
has a small hook (removal tip) in one end and a new
microphone filter in the other.
