Re: Device SN C43838523082 won't pair. with either of my enhanced remotes.
The premiere came with IR remote, but could be paired to wifi remote. The premiere 3920x model number is in bright lettering on the same line as the sn. Same for the 3921x premiere+. I own both, and I also own the IR only 3700 and it looks like yours, model number you can hardly see on the line above the sn.
