Hello guys, Just bought a Q40 , when I turn it on it gives directly a 2 tone beep and I cannot stop it.? I can adjust settings etc but the tone stays continuously and cannot get ride of it. I reset the unit to factory defaults also but the problem stays. Tried several things. Checked the connection between cable and unit but no go.. The text 'raise coil ' is also something I don't understand,it stays visible all the time. Does any one now what this means.? Regards, Patrick
