In my ham radio room stray RFI gets into my 00600 station with 5-1 weather monitor . It causes the touch light to malfunction and all the controls to malfunction. The settings button turns the light on and off. Once in this condition you have to remove power and reset the station thereby starting the self calibration all over again. Had to move it away from the equipment thereby rendering it impossible to connect it to the computer. I put ferrite cores on all the cables and that helped but eventually it still fell victim; as I was transmitting I looked over and the display light was going on and off as I talked sad but I suppose it was just not designed to work in this environment. Love this weather station beautiful little setup.
