Waters 486 tunable UV detector

Hello, everyone. I have a problem with Waters 486 tunable UV detector. This detector was fine yesterday, but this morning it shows '7FF2' error code.
All knobs are disabled. This error code is not listed in the manual... Any suggestions? Thanks

I guess you've powered the detector down between "yesterday" and "today".
If so, I'd suspect the backup battery. Have you ever replaced it? You might need to replace it now.

Best Regards
