Maintaining completely-in-canal hearing aids

Here you find advice on how to maintain and clean a completely-in-canal (CIC) hearing aid.

The hearing aid is worn deeply in the ear canal. It is very important for its performance that the instrument is free from ear wax and dirt.

Clean the hearing aid daily with a soft, dry cloth. Never wash the hearing aid with water, cleaning solutions or other liquids.

We recommend that every time the hearing aid is taken out of the ear, you inspect the sound outlet and the microphone and relief vent openings to ensure that no dirt has gathered there.

Below is an example of how the sound outlet and the relief vent and microphone openings can be positioned.

Cleaning the sound outlet

If the sound outlet is blocked by ear wax or moisture, remove the wax with the special removing tool enclosed with the hearing aid (small brush), and remove the moisture with a small blower. Do not insert any objects into the sound outlet.

Cleaning the microphone opening

Clean the microphone opening with the wax removing tool enclosed with the hearing aid. Open the battery drawer and remove the battery. Turn the hearing aid, so the battery drawer is facing downwards. Guide the short end of the wax removing tool through the microphone opening from the inside.

Cleaning the relief vent opening

Make sure there is no wax around or in the relief vent opening. Open the battery drawer and remove the battery. Turn the hearing aid upside down, so the battery drawer is facing downwards. Make sure there is no wax in the vent as far as the long end of the wax removing tool can reach. Make it a habit to clean the relief vent opening every day.
