I have a problem with my high-frequency microphone input on my left ReSound Quattro 961 device.
I noticed that in the Smart Fit v1.7 software (the latest and the greatest) that there is a Test Device option in the dropdown menu on the right side of the fitting screen. The software advice is that when in testing mode, the user fitting will be overwritten by test settings but then restored at the end of the test.
So I try that and overall, that’s what happens. However, during the “test,” which seems to require both HA’s be involved, I just get a high-pitched feedback whine out of both tests - the receivers of each HA are outputting high-pitched noise which almost sounds like a feedback squeal (but not as high-pitched on average as actual feedback). When I get tired of listening to the sound and click “RESTORE,” my user settings are restored, a screen quickly flashes by, and I get NO test summary, etc.
And as usual for my defective left HA, when I reinsert my HA’s in each ear, the high-frequency input to the left HA works great for a minute or two before it fades away. The right HA, my original from 2018, continues to work great like a champ. I had hoped that the “Test Device” would actually run a diagnostic on both HA’s and give a full-detailed report as to the state of health of each. No such luck, apparently, unless as a DIY tester here I am missing something a HCP would know to do …
TIA for any advice on how Test Devices is supposed to work …
