FIXING COMMON ISSUES OF YOUR DEVICE
Feedback / Chirping:
If you hear a high-pitched sound when you put the device
in the ear canal, you’re having feedback. Change between
dierent dome sizes to one that ts better, and insert the
device as swiftly as possible to avoid feedback.
Battery doesn’t last:
Make sure you’re using brand new batteries straight from
the package. Its very important that you let the batteries
“breathe” or “take air” for around 5 minutes before inserting
them into your device. Furthermore, whenever you’re not
using your hearing aids expel the battery or open the battery
door to turn o the device; this will save a lot of power.
