    Default Cleaning microphone screens

    I have ongoing problems with sound quality due to my Phonak Smart XI microphone screens getting gunked up. They are easy to replace but it requires a long trip to the audi to get replacements. The indications that there's a problem are increasingly muffled sounds and "scritching" noise from my hair across the screens.

    I have discovered a cleaning routine that seems to work well. First, I remove the dirty screens then soak them in alcohol for about half an hour. Then, I dry them on a paper towel and holding them firmly blow them out using canned air (the kind they sell to clean electronic components). Warning: hold on to one end of the tiny screen FIRMLY as the force from the canned air will launch them into orbit if you lose your grip. I grasp one end, blow out the other and then reverse my hold and blow out the other end. I also discovered that blowing them out from both directions helps. Using a magnifier you can see the before and after results.

    I have two pair of these little screens and alternate them about every two weeks and have done so several times with good success.

    I hope this helps someone and will welcome any further suggestions on how to deal with this problem.

    I don't know if your aids take the same filter that mine do, I have Versatas. When I got my last aid, the audi gave me a kit of 25 or 30 of them. If you want the part number of the kit, I can post it later.

    Thanks, I'd be interested in the part number and availability. I live about 30 miles from my audi so extra trips aren't convenient.

    Why are you cleaning them with alcohol?

    Seemed like it called for some sort of solvent. The gunk in the wind screen is a combination of skin oil, dried sweat and dust. I suppose I could try water an a little detergent. What did you have in mind?

    Thanks for the info. Doesn't look like anyone has these for sale in the US. :-(

    Thanks. I emailed them, awaiting a response. I discovered the package I had for these had a different part number:

    Microphone protection set...with program switch
    REF: 004-2801-061
    F-No 2659166
    Bar Code: 7 612847781863

    I'm guessing the parts for these things are very specific to each model of aid.

    I'll let you know when I hear back from tva.

    I contacted tvahearingproducts.com. They were very helpful, had what I needed and I've placed an order. The microphone screens with the program switch are $2 each. Thanks for referring their name in this regard.
