Iphone 5s with OS 10.9.1 and Phonak Streamer (N15398 S1285 SN 1213N004J). Going to setings-accessablity-hearing aids- the phone cannot find the streamer even though I am using the streamer to make and recive calls constantly. It is the very short delay that is causing all the problems. I assume that it is mearly the time lag for the phone to connect to the hearing aids and start passing information.
