Let’s talk about Date and Timestamp;
Typically when something is written using “Electronic Writing” it includes a date×tamp. Your local database and your hearing aids/HAs have these date×tamps. Thus your Audi’s database retains his/her date×tamp that equates to your last Audi fitting session.
If you use fitting software to change the settings and you also save those settings, then your local database and your hearing aids will get a new date×tamp. If you don’t save your changed settings to the HAs then your Audi will not be aware that the hearing aids were connected to a computer and/or fitting software. But what’s the point of making changes without saving them?
Let’s look at a specific situation where your Audi adjusted your hearing aids on Christmas day, and then you changed and saved the settings on New Years day.
- Audi’s database = Christmas
- Your local database = New Years day
- HAs = New Years day
On Valentines Day you decide to return to your Audi so you restore the hearing aid settings to the Audi’s original settings (to HA only) before the Audi visit.
- Audi’s database = Christmas
- Your local database = New Years day
- Hearing Aids = Valentines Day
During the Audi visit, the Audi’s database and hearing aid date×tamps don’t match. Therefore, the fitting software will detect this mismatch and ask your Audi which settings should be used (the hearing aids or the database)? Busted!!
