Hello to all, im using to my coffe shop a PVR system AVC 760 (IDE DISK), we have change the default administrator password (0000) when we start use it (before 1 year) and now we dont remember this password, and we cant access the machine from the monitor. I have try the hardware reset with the JP2 Pins but dont reset my avc 760 administration password... is any other way to reset the machine to the system defaults? i dont care i im losing all of my configurations... thanks
