telecoil is busted

The telecoil on my Supero hearing aid has gone kooky. How that happened, I have absolutely no clue at all whatsoever. One night, I was listening to music on the computer with the Hatis Epic silhouette earhook, everything working great. The next day at work when I try to listen to music on my iPod, I couldn't hear anything! If I maxed out the volume on the iPod, then I could barely hear something. And I found it odd that I didn't hear a buzzing sound when I put my ear close to the computer on the telecoil setting. That was when I knew something was wrong. Even just switching to telecoil has an odd sound now, that wasn't there before. I relay-called Phonak to see if there was anything I could possibly do. They said probably not, that it sounded like the hearing aid would have to be sent in for telecoil to be fixed. Oh great. Called and set up an appointment with local audiologist for ... Wednesday morning I think. Will see what happens then. I'm most definitely not happy to have to go back to the old analog for telecoil function. But what else can I do?
