Why are my Phonak hearing aids blinking red/yellow/green in charger?

The indicator light on the hearing aid will show the charging state of the battery until the hearing aid is fully charged. When fully charged, the green indicator light on the hearing aid will remain on. 

Charging states: 

• 0-10%    hearing aid blinking red 
• 11-80%  hearing aid blinking yellow
• 81-99%  hearing aid blinking green 
• 100%     hearing aid light solid green
