With many thanks to Ray, who posted the entire setup manual in reply to a USENET message I posted some time ago, I'll pass along the URL for the location of the manual. I just used the CK3000 to check out another roundie chassis (Admiral 25UH-series) which had an intermittent issue with color sync. The CK3000 allows much more systematic probing, tapping, and prodding to pin down touchy intermittents than would be possible with the chassis inside the cabinet.
Here's the URL posted by Ray on USENET ...
