A funny thing may occur between versions of the Genie fitting software. An Alta1-Pro programmed with Genie 2014.2 VA (Veterans Administration) software will gave a warning when the same Alta1-Pro is connected to a non-VA version of Genie 2014.2. The warning says that the hearing aids (HAs) were programmed with a later version of Genie software even though both versions of Genie are 2014.2.
The warning goes away when the Alta1-Pro is connected with Genie 2015.1.
Note that the Alta1-Pro has the tinnitus feature which was only available to the VA until release of the Alta2. I am guessing that the VA had a different/newer version of Genie 2014.2 for fitting the tinnitus feature and after release of the Alta2, the 2015.1 version of Genie will fit all.
