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.
