Do I need a USB IR dongle in my Mini to get the RF mode to function? The remote flashes red with each button press. The settings menu says that means it isn't fully paired into RF mode. I follow the instructions to complete the pairing but it still doesn't flash yellow as it should when fully paired. The Mini is not a vox. Been searching the internet and can't find any definite word. Called tech support and spent literally over an hour doing remote resets with the tech. Then they said they would send me a new remote. I don't think there's anything wrong with the remote.
