Whistling may occur if the hearing instrument is turned on,but not securely seated in your ear.this is normal.the whistling will stop once the device is properly seated in your ear.

Whistling is common for small amplifiers and is known as "Feedback".it is caused by amplified sound from the hearing aid getting back to the micropphone and being re-amplified.The folloring tips will help reduce the occurrence of feedback whistle:
