SteelSeries Engine settings?

[Fuggan]

I don't quite understand what the LED ON/LED OFF settings are here? Also, is CPI the same as DPI?

Basically coming from an old-ish DeathAdder (didn't use any software with it), how can I set my new Sensei Raw to be exactly the same sensitivity? I believe that was 1800 DPI when plugged in and no software installed/buttons pressed.

Thanks.

Ah great, I've just twigged that the LED refers to the LED on the mouse, lol. Cheers.
