Check all the components and parts of your cochlear implants, and make sure the implant is completely cleaned and the batteries are charged. If this doesn't work, alert the hearing centre you go to and try to schedule an appointment as soon as possible.

Firstly, make your all your components are cleaned and the batteries are charged. After that, clean out the tubing and make sure there's no moisture in it via an air puffer. Also, make sure the earmold is completely in your ear.
