I bought a Siemens hearing aid in the Eye, Otolaryngology Hospital affiliated to Fudan University. Who should I ask to repair it after the expiration date?
Siemens hearing AIDS are guaranteed nationwide. Since the warranty period has expired, you can repair it in any regular Siemens hearing aid store, and you only need to charge the maintenance fee. If the chip (motherboard) is not damaged, the maintenance cost of changing the microphone and receiver is 200 yuan to 300 yuan, and the volume potentiometer is only tens of dollars.
