Feedback-Free Listening - Unitron Unison Digital ITE Guide De L'utilisateur

Feedback-Free Listening

Your Unison hearing devices may have an optional start
up mute that can be activated by your hearing
healthcare professional. If the start up mute is activated,
your hearing devices will not turn on until the program
button is pushed, even if the battery door is in the ON
position. The hearing devices return to the start up mute
position each time you turn your hearing devices on.
This allows you to insert your hearing devices without
experiencing whistling.
If you wear hearing devices now, you may have
experienced whistling from your hearing devices when
you talk, chew, use the telephone or hug someone.
Unison's feedback technology dramatically reduces this
uncomfortable whistling before you or anyone else can
perceive it.
