I tried to screw to CE on the remote controller, its like they super glued it, so i turned it to CE i think, so i opened the RC to se what happend and its a plastic thing thats being turned from CE to FCC which is kind of stupid, so it been damaged and is very hard to screw now and as i pressed the screwdriver down to get a good grip to spin the two metal leggs it stand on, one of them have been bent down, so they could make that switch easier to screw not like its super glued. Anyway i managed to turn it CCW to turn on CE and when i did and start the controller it stll beeps 2 times for FCC, so i screwed it more CCW and it can screw how many times u want, like i made 2 whole turns, and still on FCC so i left it at that, since the FCC - CE on the RC does not work. So i plugged the RC to the computer and started software for RC to switch to CE from there, ofc it says its on FCC in the software so i switched it to CE closed the program turn the remote controller off and on again, and it still beeps 2 times. I turned the software on again and it says its on CE but it beeps 2 times.. so i can not switch to CE? I am doing somwthing wrong? Is this a common issue?
