My sound processor turns off unexpectedly.


  1. Don't worry, this can be normal.

    A sound processor automatically switches off after you've taken it off and it's not connected to an implant for more than two minutes.
  2. Are you using the right batteries?

    Make sure they're the ones we recommended – 675 (PR44) zinc air batteries designed for cochlear implants.If you are using the Aqua+ accessory you'll need to change to another type of battery. There's a list of batteries on page 3 of the Aqua+ for Kanso® User Guide. Note: Let new disposable batteries stand for a few seconds after you peel off their plastic cover and before you put them into your sound processor.
  3. Clean your sound processor.

    If sand or dirt get into the processor, remove it by carefully brushing all indents and holes in the processor's casing.
  4. Replace the batteries.

    There's a step-by-step guide for how to do this on page 6 of your user guide.
