Feedback-Free Listening
Your
360
hearing devices have an optional start up delay
that can be activated by your hearing healthcare
professional. If the start up delay is activated, your
hearing instruments will not turn on for 10-15 seconds
after the battery door is closed fully. The hearing
instruments return to the start up delay position each
time you turn your hearing instruments on. This allows
you to insert your hearing instruments without
experiencing whistling.
If you wear hearing instruments now, you may have
experienced whistling from your hearing instruments
when you talk, chew, use the telephone or hug
someone.
360
’s feedback technology dramatically
reduces this uncomfortable whistling before you or
anyone else can perceive it.
