Hey guys.

I am trying to get my Spector legend 5 in tune with itself by adjusting the intonation, but I don't know how to do it on this particular bass.
Looking on the website it has a "Spector Die Cast Locking Bridge". Does anyone have any experience with these bridges?

Basically it has 2 hex screws in each saddle, one is closer to the head of the bass than the other one, and I don't know which one is string height and which adjusts the length. It says something about it being a locking bridge on the spector website, but doesn't go into any detail of how to unlock/lock do anything with the bass.

Any help is greatly appreciated.

here is a link to a pic of a bass with a very similar looking bridge (mine is black, this one is gold).
