Notification Icon like an ear

[Slobodan Savovic]

I can not turn off notification icon that looks like an ear. I think it is hearing aid but in my settings I can not find where it is. I tried in CALL SETTINGS and I also tried in ACCESSABILITY SETTINGS but no luck. My xperia m2 is running on 4.3
please anybody help

It's for Hearing Aid Compatibility. Xperia™ Z1S - User guide (English [United States]). The link is for the Z1S manual, but the section talks about HAC.
