Hello
I have a KX-NSX1000 that has version 2.030 and its maintenance license has expired. The system was activated last year and I need to know if there is a way to update the cabinet without a license or through a USB memory stick. Does anyone have any news if Panasonic will open the maintenance keys? .. greetings
