Always insert the battery in the door: never directly into the hearing
aid. Gently close the battery door.
NOTE:
Always use new zinc-air batteries that have a minimum remaining shelf life of one year.
When the hearing aid is not in use, open the battery door to turn it off. Open the battery door completely
to allow moisture to evaporate and prolong the hearing aids’ lifespan.
If the hearing aids are experiencing frequent loss of connection to wireless accessories, contact your
hearing care professional for a list of low impedance batteries.
Battery warnings
