I cannot hear any sound or the sound comes on and off when I turn on my sound processor.
-
Check the indicator light.
The indicator light should be green. If it doesn't turn on, please see My sound processor won't turn on. -
Check that the coil is correctly positioned on the implant.
Try repositioning the coil. Sometimes the coil and implant don't line up correctly and while the coil stays on the head, there is no sound. -
Check the coil cable.
Make sure the coil cable is fully inserted into the socket on your processor. -
Is the volume setting too low?
Use the Nucleus Smart App or remote control to turn up the volume. -
Try a different program.
You can choose between programs to change the way your sound processor deals with sound (e.g. in noisy or quiet places). Use the Nucleus Smart App or remote control to switch programs. -
Try a different coil cable if you have one.
If you have another coil cable, try using it. If this helps, there may be an issue with the original coil cable.
Make sure you're using the correct coil for your implant type. Contact our customer support team if you need extra help to replace the faulty coil cable. -
Change the batteries.
There's an easy step-by-step guide for how to do this in your Nucleus 8 Sound Processor User Guide. Note: Rechargeable batteries have a built-in "health check". If a charged battery detects a problem, it will turn the sound processor off. If the problem is fixed, it will turn back on again. If a battery turns off, disconnect and reconnect it to your processor. If this doesn't restore power, contact your clinician. -
Check with your clinician.
If you've recently had your sound processor replaced and the problem continues, please contact your clinician.
