Daily use and care

Most people with a sound processor find that it quickly becomes a natural part of their life. To keep your sound processor in good condition, it’s important that you look after it. This section gives you some practical tips on caring for your sound processor.


  • You should regularly clean the outside of your sound processor and its accessories using a cleaning wipe, or a stiff bristled brush that has been lightly moistened with alcohol. This will remove any dust and perspiration residue.
  • The protective case can be used to store your sound processor when you are not using it. It can also be used with the carrier for greater protection, especially during travel.


A number of spare parts are available for Oticon Medical cochlear implants. Below you can read about the most common issues you may encounter. For more information, please read the sound processor’s instructions for use.

Finding the serial number

Your sound processor has a serial number written on the inside of the battery door. You should have this information if you need to contact our Customer Service.

Changing batteries

To change the batteries, just open the battery door and insert correctly as shown. Close the battery compartment and turn on your sound processor.

Changing ear hook

The ear hook of the sound processor is available in a variety of sizes. To change an ear hook, remove the used hook and replace it by clicking on a new hook.

Changing cable and/or antenna

The ends of your sound processor’s cable and antenna come with a foolproof key. When connecting the cable to the sound processor, as well as the cable to the antenna, this key must face in the right direction in respect to the socket and the cable. When removing the cable, ensure you hold the end of the cable. Don’t pull on the cable itself.

Checking microphones

If the microphone earphones are plugged into the auxiliary socket, a hearing person will be able to listen to the audio signals when the sound processor is turned on. This allows others to detect any microphone problems.

Checking the sound processor

To help you diagnose any problems with your sound processor or accessories, a number of diagnostic tools are available. Either place the antenna on the tester or use the self-check function on Neuro One by pressing the push button. The indicator light will then reveal if your equipment is working optimally. If you don’t find the information you are looking for, please see the Quick Diagnostic Guide.
