I was initially concerned that I needed the Costco Target software, however it appears I don’t. The problem seems to be the other way around in that the Costco software won’t program Phonak aids other than those sold at Costco !
Refer quotation from post here:
“Anyway, I have a Hi-Pro USB and the Target 3.3 software and have been making some tentative adjustments to the Brios. So, yes, the Brios are not locked and can be programmed with Target 3.3. I have not tried Target 4.0 which I also have, primarily because Costco also uses Target 3.3 and I want to be able to discuss the program with the Costco fitter. As I understand it, the Costco Target software is crippled so that it will only work on Costco supplied HAs.” (http://www.hearingaidforums.com/showthread.php?17786-Can-Costco-Phonak-Brio-HA-s-be-adjusted-with-a-Hi-Pro-USB-amp-Phonak-Target-4-0-software)
