Oh wow, you got good eye sight.
I think I know what’s happened then.
A long time ago, I had a Oticon CI adaptor that used a size 13 battery and could attach a Roger X but I used it with an old recorder that hearing people could place near the person speaking.
Stupidly I sold it because I then couldn’t make out what people were saying on the dictate phone thing.
I had the CI adaptor way before Speech to Text Apps were around.
I wonder if this is a work around that doesn’t need a size 13 battery.
I’ll investigate more.
