My new BTE aids have a “Telecoil” push-switch. When I push it, the aid beep-beeps, and stops ( I assume the mike is simply turned OFF). Push it again, it beeps once and returns to normal operation.
The manual says… it toggles between Mike, Telecoil, and mixed-mode(MT) ???
Does it have a telephone-coil ? How do I test it ?
( it does nothing when using my cell phone, or wireless home phones )
Is the battery in use ? Can I use it like a power on/off switch ?
