I recently aquired a used STi Driver (manufactured the last week of 2005) and was wondering if it has had the firmware upgrade to address the Ramp-Up that so many complained about.
On a phone call to Beltronics, they confirmed that the unit was in for an internal speaker repair a few months ago, and that the 33.8Ka "fix" would have been done if it needed it, but they do not do the Ramp-Up fix unless specifically requested.
I have been told this by one representative, and that it "was probably done" from another rep
Is there a way that I can test the detector to see if the Ramp-Up has been done? perhaps test it near a set of automatic doors? If so, what exactly would I be looking for
