Removing Feedback/Squeal
Your hearing aid may have the ability to address
feedback (whistle/squeal).
To remove feedback:
1. Make sure you are in a quiet environment.
2. Press and hold the program button on your hearing
aid for four seconds until you hear tones.
Note: If you do not hear the tones, this feature is
not enabled for your hearing aid.
3. Remove your finger from the program button and
from the vicinity of the hearing aid. You will hear
several bursts of noise.
After your hearing aid is trained you will hear the power
up tones play. Your hearing aid will return to your first
listening program.
