Welcome to our forum.
Just how BIG are those power lines you live under?? They're obviously jamming your signal
May have to reposition the items plugged into the ICOM HUB or replace the HUB( expander board on the IQ2020 board.). Have your dealer do it. It's under warranty
Hey did you try syncing it up? Take the remote with you to the main controls. Then hold light + and - at the same time. Do this until it says its syncing. Wait untill its done and see if that fixed your problem. This needs to be done with a new remote so that they communicate properly.
Are you holding them down with 1 finger or 2. I have heard people say the same thing, and it was the way they were pressing it. If it doesnt say Sync withing 10 seconds, you either aren't pressing both down right or somethings broken.
I hope you get your remote problem resolved soon. Remote isses aside, how does the Spaudio II sound? Are you satisfied with it?
