Kanso®

My sound processor won't turn on.


  1. Are you using the right batteries?

    Make sure they're the ones we recommend – 675 (PR44) zinc air batteries designed for cochlear implants. Also, check if the seal has lifted from the battery. If it has, the battery could have lost its charge because it's been exposed to air.
    If you're using the Aqua+ accessory you'll need to change to another type of battery. You can find 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.
  2. Check that there's no dirt or dust on the battery contacts.

    Use the cleaning brush and wipe the sound processor with a soft cloth to clean the battery contacts without bending them. You'll find step-by-step pointers for how to clean these items on page 33 of your user guide.
  3. Replace the batteries.

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