Mute
If you are in a program for which Tinnitus
SoundSupport is activated, the mute functionality
will mute only the environmental sounds, and not
the sound from Tinnitus SoundSupport. See chapter:
"Mute the hearing aid".
Volume adjustments with Tinnitus
SoundSupport
When you select a hearing aid program for which
Tinnitus SoundSupport is activated, your hearing
care professional can only set the push button on
your hearing aid to work as a volume control for the
tinnitus relief sound.
Your hearing care professional will set the volume
control for the sound generator in one of two ways:
A) change volume in each ear separately, or
B) change volume in both ears simultaneously.
