Why is there no sound coming from my Phonak hearing aids? Phonak hearing aids are not functioning. There is no sound from hearing aids (no amplification). Troubleshooting for rechargeable Phonak hearing aids models:  • Speaker or earpiece blocked: Clean speaker opening or earpiece. Change the earwax filter if  your hearing aid model is equipped with earwax protection.  • Hearing aid switched off: Press the lower part of the multi-function button for 3 seconds.  • Battery fully discharged: Charge battery.  • Hearing aid is in error state: Reboot the hearing aid: • Instruction for Phonak Infinio hearing aids: Press the push button for at least 15 seconds. It does not matter if the hearing aid is switched on or off before you start pressing the button. After 15 seconds the indicator light on the hearing aid blinks green and then turns solid green. The hearing aid is ready to use.  • Instruction for other Phonak rechargeable hearing aids: Press the lower part of the hearing aid button for at least 15 seconds. Place the hearing aid in the power-connected charger and wait until the indicator light blinks green. This can take up to 30 seconds. The hearing aid should be ready to use now.
