Place the software file (unzipped) in the root directory of your USB storage device (HDD, memory stick etc.) and connect the device to the USB port of the receiver. First a message box will appear that a USB device is found. Then go to the {System} menu and select the {USB Upgrade} option. At {Upgrade Mode} select {App All} and then select the correct file in the list. Select {Start} and press [OK] to start update. When ready, the unit will reboot automatically.

[Note]: Never interrupt a software upgrade. Do not unplug the USB device. Do not pull the power cord or switch the receiver off.
