White power shock help/user manual anyone?

[Yas1]

Hi All, I just bought an FZS1000 which has a white power shock fitted. I can see there are 3 adjusters which I'm guessing are low and high rate compression, at the top, and rebound at the bottom, but I was hoping someone might have a user manual to clarify things for me please? I can't see any markings on the shock to indicate what model it is or which adjuster is which.
Any help appreciated!
Thanks in advance,
Karl
