Oh and by the way, I promise there will be a small panic the first time you attempt to tweak your own HI. The key is to make sure that you choose the option of using the program thats IN THE HEARING INSTRUMENTS the first time you connect at home. Then, save a snap shot in case you totally botch it. Then when you go back to your audi, make sure they do the same or else your adjustments will vanish.
Either way it takes some guts. Worse case is you have to go back to your audi and start over. Big deal. Have your audiogram handy too.
