My new scope

Hello guys,
I received my Konuspro 6-24x44 scope this morning. Everything's fine, but the user manual/papers don't say much. I have no idea which power it's true at and what the distance between the dots would be at that power. I really feel like burning all my stuff. Do you have any suggestions? Going through a process of trial and error would be a waste of time I guess. Which power do you think it might be true at? You could have a look at that: http://konuspro.com/img/uploads/product/KonusPro_Instructions(26).pdf

MOD EDIT: moved to scope & optics section. Gene please start posting in the appropriate section.
