saber cam question

[Byrd]

I have a 2002 cybertec with a saber cam, it was suppose to be a excel cam. My question is the post in the cam to change letoff, I don't know which hole for what letoff. I have it in the one going toward the string not the one going toward the bow. There are only two holes.

I had a vortec with a sabre cam and I thought it had 4 holes (two on each side of the cam). any way the let off goes up as the draw gets longer.
