Now what have I done? I cleared my DAB memory and did another scan for stations. It stopped at 100 and put up BBC 3/Classic. I saved it on key 3 OK. I then tried to use the cursor arrows surrounding the OK button to find more stations but instead it indicates it is seeing them as balance controls of various kinds. I pressed the DAB input selection and held it - no subsequent difference. It was working fine when I first set up DAB but then a managed to screw up the stations assigned to some keys so I thought I'd start again. I don't recall this alternate function on the cursor keys last time. What have I overlooked?
