Feedback
sound is too
loud
The earpiece of the hearing amplifier does not fit in the
ear correctly, which may cause unpleasant whistling
sounds (acoustic feedback) and reduced function. This
can be prevented as follows:
• Lower the volume.
• Switch the device to the other ear, although using
the device in the specified ear is recommended
whenever possible. Contact Customer Service with any
questions.
• Make sure the microphone is not obscured by your ear
or hair, as this may increase the acoustic feedback.
