Supongo que dice algo, pero no logro entenderlo, intentaré traducirlo
"If you’re having trouble finding the right BPM, keep your eye on the blue square moving clockwise around the slightly bigger grey square (in the right of the BPM section). If your BPM is on the money, it should hit the top left corner on every first beat. When you find it’s drifting out of sync, and always arriving a little late, increase the BPM slightly by hitting the ‘plus’ button a few times, or hit the ‘minus’ when it’s arriving early. Now hit resync again and see if it drifts again. Repeat till you get it right. This is how DJs beat match records as well, and after a little practice, you’ll be able to dial in on the correct BPM very quickly."
