Hearing Aid Maintenance Guide

Proper maintenance of your hearing aid can significantly extend the life of the device. It can also ensure the device is working at full capacity. Below we’ve put together some helpful tips on how to properly maintain your device and how to troubleshoot any problems that may arise:

Tips on maintaining your device:


  • Keep your hearing device in a dry, cool place.
  • Turn off your hearing aid when not in use.  Remove the battery when the device won’t be in use for an extended period of time.
