In Demo Mode, you can use the Nucleus Smart App without a connection to a Nucleus 7 Sound Processor for demonstration purposes or just to try it out. You can enable/disable Demo Mode under ‘Settings’ in the Nucleus Smart App.

Yes. If you pair your compatible Apple device with your child’s Nucleus 7 Sound Processor, you can control and monitor the processor, which allows you to see battery status, adjust volume and change program without needing to touch the sound processor.

You may want to disable audio streaming to your child’s processor so that your phone call or music does not stream to their processor. You can do this by going to Settings> General> Accessibility> Hearing Devices and turning off ‘Stream to hearing device’. This will stop streaming to your child’s sound processor but still allow control via the Nucleus Smart App.

If you are unable to adjust your sound processor(s) using the Nucleus Smart App, your compatible Apple device may not have been paired properly with your processor.

To learn more about the pairing process, watch our Nucleus 7 pairing animation. If you have successfully completed the pairing process, ensure that your device is within the recommended range, and that there is nothing causing excessive interference. If the problem persists, contact Cochlear or your hearing health professional.
