Evening all. Can somebody please help me out with a problem. I keep getting a tuning error as shown in the photo attached. I have checked all cables and everything is ok. The problem is not happening on my H7s downstairs. Another message also keeps popping up about a powertimer and I can't put it into standby. I've deleted all power timers so don't know what's going on.
I've attached as much info as I can which might assist.
Any help gratefully appreciated.
TIA
