First, they have to be connected to the sound system and switched on whenever the system is on. It’s not something people should have to ask for – because they won’t.

Too often systems do not work or are not turned on and there is a lot of confusion as to how these systems operate. The best way to test a system to see if it is working is to ask someone who is wearing a hearing aid with a ‘T’ switch.

Too many systems fail to work even when technicians claim they do. Here are some of the fact sheets on the Clearasound site.
